The volcanic field’s Western character makes horseback riding a fitting way to explore the landscape. Many trails and roads permit horses, allowing equestrians to cover more ground than hikers while enjoying traditional transportation methods.
Guest ranches near the volcanic field offer guided horseback rides for visitors without their own mounts. These rides range from one-hour introductory trips to full-day excursions into the backcountry, often incorporating volcanic features and geological points of interest.
Riders bringing their own horses should research trailer parking, water availability, and any special restrictions on the specific lands they plan to visit. Some areas require weed-free hay to prevent invasive plant spread.
Winter Activities
Winter transforms the Thirtynine Mile Volcanic Field into a snow-covered wilderness requiring specialized skills and equipment. Cross-country skiing and snowshoeing provide ways to explore the volcanic landscape during cold months.
Backcountry skiing on volcanic peaks attracts experienced skiers seeking untracked powder and quiet solitude. These pursuits demand avalanche awareness, winter camping skills, and proper safety equipment including beacons, probes, and shovels.
Snowmobiling occurs on designated routes and areas during winter. Check current regulations and snow conditions before heading out, as rules change seasonally and vary by land management agency.
Travel With Children
Families visiting the Thirtynine Mile Volcanic Field discover opportunities to engage children with geology, nature, and outdoor adventure. While the remote, undeveloped character presents challenges, careful planning creates memorable educational experiences for young travelers.

Age-Appropriate Activities
Younger children enjoy exploring volcanic rocks, collecting interesting stones (where permitted), and observing wildlife more than long hikes or peak climbs. Focus activities on discovery and sensory experiences rather than distance goals.
Short walks among volcanic outcrops let kids examine different rock textures, colors, and formations. Turn exploration into games by searching for specific rock types, spotting animal tracks, or identifying wildflowers. These activities build engagement while teaching observation skills.
Older children and teenagers often appreciate the physical challenge of hiking volcanic peaks. Choose objectives matching their fitness levels and experience, building gradually toward more ambitious goals. Summit success creates powerful confidence and memorable achievements.
Educational Opportunities
The Thirtynine Mile Volcanic Field serves as an outdoor classroom teaching geology, ecology, and natural processes. Children witnessing volcanic rocks firsthand gain understanding impossible to achieve through books alone.
Explain volcanic processes in age-appropriate terms. Describe how molten rock rose from deep underground, erupting at the surface to build the peaks surrounding you. Show how different cooling rates created various rock textures. Discuss why volcanic soils support certain plants.
Visiting the South Park City Museum in Fairplay complements volcanic field exploration by showing how humans adapted to this challenging landscape. Children enjoy historic buildings and artifacts that bring the past to life tangibly.
Safety Considerations for Family Travel
Children face increased altitude risks due to their smaller body size and developing physiology. Watch carefully for altitude sickness symptoms including unusual fussiness, persistent headaches, nausea, or lethargy. Descend immediately if symptoms develop.
Sun exposure threatens young skin even on cloudy days. Apply high-SPF sunscreen frequently, covering all exposed skin. Dress children in long sleeves, long pants, and wide-brimmed hats when possible. The intense high-altitude sun causes burns much faster than at lower elevations.
Hydration becomes critical for children who may not recognize their own thirst. Enforce regular water breaks every 30 minutes during activities. Bring more water than seems necessary, as children’s higher metabolism and activity levels increase fluid requirements.
The remote nature of the volcanic field means limited access to emergency services. Carry comprehensive first aid supplies including treatments for cuts, blisters, sprains, and insect stings. Know the location of the nearest medical facility before venturing into backcountry areas.
Practical Family Travel Tips
Pack extensive snacks for children exploring the volcanic field. Hunger strikes unpredictably, and the nearest store may be an hour away. Energy bars, trail mix, dried fruit, and crackers provide portable nutrition that doesn’t require refrigeration.
Bring entertainment for vehicle time between destinations. The distances between points of interest can test children’s patience. Audiobooks, music, and car games make long drives more pleasant for everyone.
Involve children in trip planning before leaving home. Show them maps of the volcanic field, explain what volcanic rocks look like, and discuss what animals you might see. Building anticipation increases engagement once you arrive.
Set realistic expectations about activities and distances. Children tire more quickly at high altitude, and the rough terrain challenges small legs. Plan shorter adventures than you might attempt without kids, building in extra time and flexibility.
Lodging and Dining With Children
Some lodging options near the volcanic field suit families better than others. Vacation rentals with kitchens allow preparing familiar meals rather than relying on restaurants. Extra space prevents cabin fever during rest times and inclement weather.
Camping appeals to many families, creating adventure and keeping costs down. However, high-altitude camping in primitive sites challenges families unaccustomed to outdoor living. Consider starting with developed campgrounds offering bathrooms and other amenities before attempting dispersed camping.
Restaurant options remain limited and may not accommodate picky eaters. Bringing favorite snacks and supplemental food ensures children have options when restaurant selections don’t appeal. The small-town restaurants near the volcanic field serve basic American fare rather than diverse menus.
Making Memories
Family time in the Thirtynine Mile Volcanic Field creates lasting memories through shared discovery and adventure. Children remember examining volcanic rocks with parents, spotting wildlife together, and achieving hikes as a family team.
Encourage children to keep journals documenting their experiences. Drawing favorite volcanic features, pressing wildflowers, and writing about daily adventures creates tangible records of your journey. These mementos become treasured as years pass.
Take plenty of photographs but also put the camera down to be fully present. Some of the best family moments happen when you’re simply exploring together without worrying about documenting everything.
Money Saving Tips
Visiting the Thirtynine Mile Volcanic Field costs less than many Colorado destinations due to the area’s undeveloped nature and abundance of free public land access. Smart planning maximizes your budget while fully enjoying this geological wonderland.

Free and Low-Cost Activities
The volcanic field itself charges no entrance fees. Unlike national parks requiring admission, the public lands composing most of the volcanic field welcome visitors without cost. Hiking, sightseeing, wildlife watching, and geological exploration all happen freely.
Many excellent viewpoints and volcanic features sit immediately adjacent to roads, requiring no hiking fees or guide services. Simply driving through the area and stopping at pullouts costs only fuel, making scenic drives highly economical activities.
Dispersed camping on Bureau of Land Management and Forest Service lands remains free, though requiring more self-sufficiency than developed campgrounds. If equipped for primitive camping, you can avoid nightly campground fees while experiencing maximum solitude.
Timing and Seasonal Savings
Visiting during shoulder seasons in May, June, and September often yields lodging discounts compared to peak July and August rates. The weather remains generally good during these months, with the added benefits of fewer crowds and lower accommodation costs.
Weekday travel typically costs less than weekends for lodging in nearby towns. If your schedule permits flexibility, arriving Sunday through Thursday can reduce nightly room rates significantly.
Accommodation Strategies
Camping dramatically reduces lodging costs compared to hotels and motels. Developed campgrounds near the volcanic field charge modest fees, typically around $15-25 per night, accommodating multiple people in one site. This beats even budget motel rates when traveling as a family or group.
Vacation rentals sometimes offer better value than hotels for groups or families staying multiple nights. Dividing the total cost among several travelers reduces per-person expenses while providing kitchen facilities that enable preparing meals instead of eating all restaurant fare.
Some dispersed camping areas near the volcanic field offer completely free overnight stays. Research specific locations and regulations before arriving, ensuring you understand rules and can practice Leave No Trace principles.
Food and Dining Savings
Preparing your own meals saves considerably compared to restaurant dining for every meal. Bringing coolers stocked with groceries from larger cities provides ingredients at lower prices than small mountain town stores.
Picnicking during midday exploration eliminates lunch restaurant expenses while letting you dine surrounded by volcanic scenery. Sandwiches, fruit, and trail snacks cost pennies compared to restaurant meals and taste better when enjoyed with million-dollar views.
Evening meals cooked at your campsite or vacation rental reduce dining costs while creating enjoyable group cooking experiences. Simple one-pot meals, grilled meats and vegetables, or pasta dishes provide satisfying dinners without restaurant prices.
When eating at restaurants, breakfast offers the best value. Mountain town cafes serve generous portions at reasonable prices, providing fuel for active days ahead. Lunch and dinner tend to cost more for similar portion sizes.
Transportation Savings
Fuel costs constitute a major expense when exploring the volcanic field’s dispersed features. Consolidate your driving by planning logical routes that minimize backtracking. Study maps before departing each day to create efficient itineraries.
Carpooling with other travelers reduces per-person fuel costs if you meet compatible groups. Online forums and social media groups for Colorado outdoor enthusiasts sometimes facilitate connections between travelers heading to similar destinations.
Renting a fuel-efficient vehicle instead of a large SUV saves on gas, though weigh this against the accessibility benefits of higher clearance vehicles for rougher roads. Sometimes the fuel savings from a compact car get offset by inability to reach certain volcanic features.
Activity and Equipment Costs
Borrowing or renting camping and outdoor equipment costs less than purchasing new gear for a single trip. Many outdoor retailers rent tents, sleeping bags, backpacks, and other equipment. Friends and family members often happily loan gear for your adventure.
Free geological information from land management agencies replaces expensive guidebooks. Stop at Forest Service or BLM offices to collect maps and information sheets describing volcanic features and access routes at no charge.
Photography from your phone eliminates camera equipment expenses while still capturing memories. Modern smartphones produce excellent photos sufficient for most travelers’ needs without investing in dedicated camera gear.
Avoiding Hidden Costs
Vehicle damage from rough roads can create unexpected expenses. Drive cautiously on unpaved routes, respecting your vehicle’s limitations. A flat tire or broken suspension from overly ambitious backcountry driving costs far more than the time saved pushing your vehicle’s capabilities.
Medical emergencies become expensive quickly, especially in remote areas requiring helicopter evacuation. Purchase travel insurance covering emergency medical care and evacuation if your regular health insurance lacks adequate coverage for rural Colorado adventures.
Parking tickets and camping citations add unwanted costs. Follow all posted regulations, camp only in designated areas, and display required passes or permits to avoid fines.
Safety & Local Customs
Understanding safety considerations and respecting local customs ensures positive experiences in the Thirtynine Mile Volcanic Field area. The remote setting and frontier character of this central Colorado region require awareness and preparedness beyond typical tourist destinations.

Wilderness Safety Essentials
The Thirtynine Mile Volcanic Field’s remoteness means you must rely on self-sufficiency when problems arise. Cell phone coverage remains spotty to nonexistent throughout much of the area, preventing quick calls for help during emergencies.
Always inform someone of your plans before heading into the volcanic field. Provide specific details about your intended route, destinations, and expected return time. This information becomes critical if search and rescue teams need to locate you.
Carry the ten essentials on every outing: navigation, sun protection, insulation, illumination, first aid, fire, repair kit, nutrition, hydration, and emergency shelter. Even short hikes warrant these basics given the area’s remoteness and unpredictable mountain weather.
Know how to signal for help without cell service. Whistle blasts in patterns of three indicate distress to other hikers or campers who might be within earshot. Bright colored clothing or emergency blankets can signal aircraft during search operations.
Weather-Related Hazards
Lightning presents serious danger during summer afternoon thunderstorms. Avoid being the tallest object on ridges or peaks when storms approach. Descend to lower elevations and shelter away from isolated trees, metal objects, or water.
If caught in lightning, crouch low on the balls of your feet, minimizing ground contact while avoiding lying flat. Keep at least 15 m (50 feet) from companions to prevent group injuries from ground current.
Hypothermia threatens year-round at high altitude where temperatures can drop below freezing even during summer. Wet clothing accelerates heat loss, making quick changes into dry layers essential if you get soaked by rain or creek crossings.
Recognize hypothermia symptoms including shivering, confusion, fumbling hands, and slurred speech. Treatment requires warming the person through dry clothing, warm beverages, and body heat sharing if necessary. Severe cases demand immediate evacuation to medical care.
Altitude Illness Prevention
Acute mountain sickness affects many visitors to the Thirtynine Mile Volcanic Field. The entire area sits above 2,400 m (8,000 feet), with many peaks exceeding 3,600 m (12,000 feet). This elevation causes various physiological stresses.
Acclimatize gradually by spending a night or two at moderate elevation before attempting strenuous activities or high peaks. If driving directly from low elevation, take the first day easy with minimal exertion.
Hydration helps prevent altitude sickness. Drink substantially more water than normal, aiming for clear to pale yellow urine color. Avoid alcohol during your first days at altitude, as it worsens dehydration and altitude effects.
Recognize serious altitude illness symptoms requiring immediate descent: severe headache unrelieved by pain medication, vomiting, confusion, difficulty walking, or shortness of breath while resting. These indicate life-threatening conditions demanding evacuation to lower elevation and medical care.
Wildlife Safety
Black bears inhabit forested areas of the volcanic field. While rarely aggressive toward humans, bears defend food sources and cubs vigorously. Store all food and scented items in bear-resistant containers or proper bear hangs when camping.
If encountering a bear, make yourself appear large, speak in calm firm tones, and back away slowly while facing the animal. Never run, which triggers chase instincts. Fight back aggressively if a black bear attacks, targeting the face and snout.
Rattlesnakes occasionally appear in lower elevation areas, particularly among rocks and brush. Watch where you place hands and feet when scrambling over rocks. Give snakes space to retreat if encountered, as they prefer avoiding confrontation.
Tick-borne illnesses including Colorado tick fever occur in the region. Check for ticks after outdoor activities, removing any found with fine-tipped tweezers. Save removed ticks in case symptoms develop later, helping doctors identify appropriate treatment.
Local Customs and Etiquette
Rural central Colorado maintains Western ranching culture with values emphasizing self-reliance, neighborliness, and respect for property. These customs differ from urban or coastal attitudes, and understanding them helps build positive relationships with locals.
Respect private property absolutely. Much land near the volcanic field remains privately owned, often by ranching families with deep roots in the area. Always ask permission before crossing private land, and respect “No Trespassing” signs without exception.
Gates found closed should remain closed, and those found open should stay open. This simple rule prevents livestock from wandering where they shouldn’t while allowing intended access. Ranch gates control crucial aspects of grazing management.
Small-town Colorado moves at a different pace than cities. Expect slower service, limited hours, and more casual approaches to business. Rushing or demanding special treatment violates local norms. Patience and friendliness open more doors than urban assertiveness.
Environmental Ethics
Leave No Trace principles protect the Thirtynine Mile Volcanic Field for future visitors. Pack out all trash, including small items like energy bar wrappers and orange peels. If you packed it in, pack it out.
Stay on established trails and routes when they exist. Creating new paths erodes soil, damages vegetation, and scars the landscape. The fragile high-altitude environment recovers slowly from damage.
Leave rocks, plants, and cultural artifacts undisturbed. While collecting a few small stones for personal use may be permitted on some public lands, wholesale rock removal damages sites for others. Never disturb historic structures or archaeological sites.
Campfires require careful consideration. Use existing fire rings when available, or better yet, use camp stoves instead. Never build fires during dry conditions or in areas where regulations prohibit them. Extinguish fires completely before leaving, ensuring ashes are cold to the touch.
Emergency Resources
Know the location of the nearest hospital before venturing into the volcanic field. Facilities in Fairplay provide basic emergency care, while more serious injuries require transport to larger hospitals in Colorado Springs or Denver.
Park County Sheriff’s Office coordinates search and rescue operations. If you need emergency assistance and have cell service, dial 911. Provide as much location detail as possible, using GPS coordinates if available.
The nearest ranger stations can provide weather updates, road condition reports, and emergency assistance during business hours. Stop by these offices when planning your activities to gather current information and let staff know your plans.

Route Planning for Multi-Destination Trips
Combining the Thirtynine Mile Volcanic Field with nearby destinations requires strategic planning. The distances between attractions mean you’ll spend significant time driving scenic but slow mountain roads.
Consider basing yourself in one location for several days rather than moving lodging frequently. This reduces packing and unpacking while allowing deeper exploration of each area. The volcanic field warrants at least two to three days for thorough exploration.
Study maps to create logical routes connecting destinations efficiently. Some combinations work better than others based on geography. For example, combining the volcanic field with Pikes Peak and Great Sand Dunes creates a sensible southern Colorado loop.
Practical Travel Tips
Successfully navigating the Thirtynine Mile Volcanic Field and surrounding central Colorado region requires practical knowledge beyond standard travel advice. These field-tested tips help you avoid common problems and maximize your volcanic field experience.
What to Pack
Layered clothing proves essential for central Colorado’s variable temperatures and rapidly changing weather. Start with moisture-wicking base layers, add insulating mid-layers, and top with waterproof outer shells. This system allows adjustment throughout the day as conditions change.
Sun protection requires multiple strategies. High-SPF sunscreen, UV-blocking sunglasses, wide-brimmed hats, and long-sleeved lightweight shirts all contribute to preventing painful burns from intense high-altitude sun. Reapply sunscreen every two hours during outdoor activities.
Sturdy hiking boots with ankle support and aggressive tread handle the rocky volcanic terrain better than running shoes or casual footwear. Break in boots before your trip to prevent blisters during hikes.
Bring more water capacity than you expect to need. The dry air and high altitude increase fluid requirements significantly. Collapsible water bottles or hydration bladders provide flexible carrying capacity without weight when empty.
Technology and Communication
Download offline maps before losing cell coverage. Google Maps, Gaia GPS, and other applications allow downloading map data for offline use. This capability proves invaluable when exploring areas without cell service.
Portable battery packs keep phones and GPS devices charged during multi-day adventures. Solar chargers work well in Colorado’s sunny climate but require sunny weather and time to generate meaningful power.
Consider satellite communication devices for serious backcountry travel. InReach, SPOT, and similar devices provide emergency communication capabilities even without cell coverage, adding critical safety margins for remote exploration.
Health and Wellness
Prescription medications should be packed in quantities exceeding your planned trip length. Delays due to weather, vehicle problems, or simple desire to extend your stay become easier to accommodate with medication reserves.
Basic first aid supplies should include treatments for common outdoor injuries: adhesive bandages, antibiotic ointment, pain relievers, anti-inflammatory medications, blister treatments, athletic tape, and elastic bandages for sprains.
Personal medications for altitude headaches can make visits more comfortable. Ibuprofen or acetaminophen addresses mild altitude headaches. Prescription altitude medications like acetazolamide help some people, though discuss with your doctor before the trip.
Photography Tips
Early morning and late afternoon provide the best light for photographing volcanic landscapes. The low-angle sun emphasizes terrain textures and creates dramatic shadows that reveal geological features.
Cloudy days create excellent conditions for photographing volcanic rocks close-up. The even lighting prevents harsh shadows while bringing out subtle color variations in the stone.
Include people in some landscape shots to provide scale. Volcanic features appear more impressive when viewers can judge their size relative to human figures.
Protect camera equipment from dust on unpaved roads. Keep gear in sealed bags when driving rough routes, as fine volcanic dust penetrates camera mechanisms if exposed.
Vehicle Maintenance
Check tire pressure before heading into the volcanic field. The elevation change from departure points to the high-altitude field affects pressure. Properly inflated tires handle rough roads better and reduce puncture risks.
Carry a full-size spare tire, not just temporary emergency spares. The distance from services means you might drive many miles on a spare, requiring full capability rather than limited-use temporary tires.
Bring basic tools including tire pressure gauge, flashlight, jumper cables, and basic hand tools. Simple roadside repairs become possible with minimal equipment, while lacking tools leaves you helpless with preventable problems.
Environmental Responsibility
Human waste disposal in the roadless volcanic field requires planning. Carry waste bags for packing out toilet paper and hygiene products. Bury solid waste in cat holes at least 15 cm (6 inches) deep and 61 m (200 feet) from water, trails, and camps.
Minimize noise to preserve the area’s wild character. Loud music, shouting, and other noise pollution disturbs wildlife and degrades experiences for other visitors seeking solitude in nature.
Respect wildlife by observing from distance. Never feed animals, which habituates them to humans and creates dangerous situations. Use telephoto lenses for close-up photographs rather than approaching animals.
Time Management
Everything takes longer than expected at high altitude. Hikes require more time due to reduced pace from thinner air. Driving rough roads proceeds slowly. Account for these factors when planning daily schedules.
Build buffer time into plans for weather delays, unexpected discoveries, and simply enjoying the scenery. Rushing through the volcanic field misses much of what makes it special.
Start activities early to avoid afternoon thunderstorms and maximize productive daylight hours. Summer days offer long daylight, but starting hikes by 7:00 or 8:00 AM provides substantial advantages.
Local Knowledge Sources
Stop at ranger stations and visitor centers before exploring. Staff provide current conditions, suggest routes matching your interests and abilities, and share insights impossible to gain from online research.
Talk with locals in small towns near the volcanic field. Shop owners, gas station attendants, and restaurant servers often know hidden gems and can warn of current issues like road closures or problem bear activity.
Online forums and social media groups focused on Colorado outdoor recreation contain recent trip reports and updates. These resources complement official information with real-world recent experiences.
