Hidden among southern Utah’s red rock country lies a secret that even many locals overlook. While nearby Zion National Park draws millions of visitors each year, Gunlock Reservoir remains surprisingly peaceful. This 266-hectare (658-acre) oasis receives just a fraction of the crowds. Yet it offers the same stunning desert scenery, crystal-clear waters, and year-round sunshine.
The reservoir sits just 24 kilometers (15 miles) northwest of St. George. It creates a perfect basecamp for exploring southwestern Utah’s natural wonders. Whether you seek adventure on the water, trails through red rock canyary canyons, or simply a quiet place to watch desert sunsets, Gunlock delivers.
This guide reveals everything you need to plan an unforgettable visit to one of Utah’s most underrated outdoor destinations.
Getting There & Planning Your Journey
Reaching Gunlock Reservoir is straightforward from several major airports. St. George Regional Airport sits closest, just 32 kilometers (20 miles) away. This small airport offers limited flights but provides the quickest access. Las Vegas McCarran International Airport lies 193 kilometers (120 miles) southwest. It serves as the primary gateway for most visitors with frequent flights and rental car options.
Salt Lake City International Airport sits 483 kilometers (300 miles) north. The drive takes about five hours but showcases stunning Utah scenery along Interstate 15.
From St. George, take Old Highway 91 north toward the small community of Gunlock. The road winds through typical southwestern desert terrain. Red rock formations rise on both sides. After passing through Gunlock town, follow signs to Gunlock State Park. The final approach offers your first glimpses of the blue water contrasting against rust-colored cliffs.
The reservoir area has no public transportation. A personal vehicle is essential for visiting. The access roads are paved and suitable for all vehicles. However, some recreation areas require short drives on maintained dirt roads.
Travel Tip
Download offline maps before your trip. Cell phone coverage around Gunlock Reservoir can be spotty. Having navigation available offline prevents getting lost in the remote desert landscape.
Best Time to Visit & Weather Tips
Gunlock Reservoir welcomes visitors year-round thanks to southern Utah’s mild climate. However, each season offers distinct advantages and challenges.
Spring (March through May)
Spring ranks as the ideal time to visit. Temperatures range from 18°C to 27°C (65°F to 80°F). Wildflowers bloom across the desert landscape. Water levels typically peak after winter runoff. The weather stays comfortable for hiking and water activities alike.
Summer (June through August)
Summer brings intense heat with temperatures often exceeding 38°C (100°F). Early morning and evening hours offer the best conditions for outdoor activities. The reservoir provides welcome relief from the desert heat. Water sports become the primary attraction during these months.
Fall (September through November)
Fall delivers another excellent visiting window. Temperatures drop to comfortable ranges between 21°C and 29°C (70°F and 85°F). Crowds thin out after Labor Day. The intense summer heat fades while days remain warm and pleasant.
Winter (December through February)
Winter sees the fewest visitors but offers unique advantages. Daytime temperatures average 13°C to 16°C (55°F to 60°F). Fishing improves as bass move to shallower waters. The area rarely sees snow, and sunny days predominate. Winter camping provides solitude and stunning star-filled skies.
Best Months: April, May, September, and October offer the perfect combination of pleasant weather, good water levels, and smaller crowds.
Avoid If Possible: July and August bring extreme heat that limits daytime outdoor activities. Late summer may also see lower water levels.
Notable Annual Festivals
The Gunlock area itself hosts no major festivals. However, nearby St. George offers several annual events worth timing your visit around:

Getting Around Locally
Getting around Gunlock Reservoir requires a personal vehicle. No shuttle services or public transportation operate in this remote area. The main access road circles the reservoir, providing entry points to various recreation sites.
Most visitors base themselves in nearby St. George, which offers full services and accommodations. The drive from St. George to Gunlock takes about 25 minutes. Parking areas at the reservoir include the main boat ramp, day use areas, and camping sites.
Some trailheads require brief drives on maintained dirt roads. These routes remain accessible to standard passenger vehicles in dry conditions. After rain, roads may become muddy and challenging. Four-wheel drive helps but is rarely necessary.
Bicycles work well for exploring the area, though be prepared for hills and limited shade. The quiet roads around the reservoir attract cyclists seeking scenic routes away from traffic.
Where to Stay
Gunlock State Park provides the only accommodations directly at the reservoir. The park offers primitive camping sites perfect for those seeking an authentic desert experience.
Camping at Gunlock State Park
The state park maintains several camping sites along the reservoir’s edge. Each site includes a picnic table and fire ring. No hookups or shower facilities exist. Vault toilets serve the camping area. The primitive nature keeps the experience affordable and peaceful.
Camping fees run $15 per site per night. Day use costs $10 per vehicle. An annual Utah State Parks pass ($75) provides unlimited access to all state parks including Gunlock. Reservations are not accepted. Sites operate on a first-come, first-served basis.
Water is not available at campsites. Bring plenty of drinking water for your entire stay. The nearest services lie in the small community of Gunlock, about 8 kilometers (5 miles) away.

Dining & Local Cuisine
Gunlock Reservoir itself offers no dining facilities or restaurants. Visitors should plan accordingly by packing food and plenty of water for their day trips or camping stays.
Self-Catering Options
The small community of Gunlock has limited services. A small convenience store sells basic supplies and snacks. For full grocery shopping, St. George provides numerous supermarkets and specialty food stores.
Pack a cooler with drinks and perishables for day visits. The desert heat quickly spoils food left in vehicles. Bring more water than you think you will need. The dry climate causes rapid dehydration.

- Casual dining chains line the main commercial strips
- Local restaurants feature steaks, burgers, and regional specialties

Attractions, Sightseeing & Activities
Gunlock Reservoir shines as a destination for outdoor recreation. The variety of activities appeals to adventurers and relaxation-seekers alike.
Boating and Water Activities
Boating ranks among the most popular activities at Gunlock Reservoir. A concrete boat ramp provides easy water access. The reservoir welcomes all motorized and non-motorized watercraft. No size restrictions or horsepower limits apply, though most boats stay under 6 meters (20 feet) due to the access limitations.
Kayaking and stand-up paddleboarding offer excellent ways to explore the reservoir’s coves and shoreline. The calm waters suit beginners and experienced paddlers. Rental services do not exist at the reservoir. Bring your own equipment or rent from St. George outfitters before arriving.
Personal watercraft and water skiing are permitted. The reservoir’s size allows for these activities while maintaining peaceful areas for fishing and wildlife watching.
Watercraft Launch Information
Watercraft launches cost $10 per day at the boat ramp. The ramp operates year-round but conditions vary with water levels. Check current levels before trailering large boats. Spring typically offers the highest water levels and best launching conditions.
Fishing
Gunlock Reservoir provides excellent fishing opportunities year-round. Largemouth bass represent the primary sport fish. The reservoir also holds bluegill, channel catfish, and occasional rainbow trout.
Bass fishing peaks in spring and fall when water temperatures remain moderate. Winter fishing can be productive as bass concentrate in shallower areas. Summer sees fish moving to deeper, cooler water during midday heat.
Shore fishing works well along much of the reservoir’s edge. Boat fishing allows access to deeper water and submerged structures where larger fish hide. A valid Utah fishing license is required for anyone 12 years and older.
Gunlock Falls Trail
The trail to Gunlock Falls stands out as the area’s signature hike. This moderate trail stretches approximately 7 kilometers (4.5 miles) round trip. The path follows the Santa Clara River through a scenic red rock canyon.
Water flows over the falls seasonally, with peak flow occurring in spring. Even when reduced to a trickle in summer, the canyon scenery justifies the hike. The trail involves some rock scrambling and water crossings. Wear sturdy footwear with good grip.
The trailhead sits near the reservoir’s western edge. Parking is limited. Arrive early on weekends during peak season. The hike takes 2-3 hours for most visitors at a comfortable pace.
Museums, Cultural Spots & Festivals
Gunlock Reservoir offers limited cultural attractions on-site. The area’s appeal centers on natural beauty rather than museums or historical sites. However, the surrounding region contains significant cultural resources worth exploring.
Native American Heritage
The Gunlock area lies within the ancestral territory of Southern Paiute peoples. Evidence of their presence remains scattered across the landscape. Rock art sites exist in the nearby canyons, though specific locations are protected and not publicized to prevent vandalism.
Visitors should treat any archaeological resources with respect. Federal and state laws strictly prohibit disturbing, removing, or damaging artifacts or rock art.
Cultural Attractions in St. George
St. George offers several museums and cultural venues for those interested in regional history:
- St. George Dinosaur Discovery Site at Johnson Farm showcases thousands of dinosaur tracks
- Daughters of Utah Pioneers Museum displays pioneer-era artifacts and history
- St. George Art Museum features rotating exhibitions in a restored historic building
- Historic downtown St. George includes pioneer-era buildings and the striking St. George Temple
These attractions provide context for understanding the human history of the region. They make excellent alternatives during the hottest parts of summer days.
Nature & Outdoor Experiences
The natural environment around Gunlock Reservoir creates endless opportunities for outdoor exploration and wildlife observation.
Wildlife Watching
The reservoir and surrounding desert support diverse wildlife. Water birds frequent the shoreline year-round. Herons, egrets, and cormorants hunt in shallow areas. Ducks and geese appear during migration seasons.
Desert bighorn sheep occasionally visit the reservoir to drink. Early morning and late evening offer the best chances for spotting these impressive animals. Mule deer are common throughout the area.
Lizards scurry across rocks during warm hours. Watch for colorful collared lizards and the larger desert spiny lizards. Snakes including rattlesnakes inhabit the area. Give them space and watch where you step.
Photography Opportunities
The dramatic landscape provides exceptional photography subjects. The contrast between red rocks and blue water creates striking compositions. Dawn and dusk offer the best lighting for landscape photography.
The reservoir’s western shore provides excellent sunset viewing positions. Reflections of surrounding cliffs shimmer on calm water. Spring wildflowers add splashes of yellow and purple to the rust-colored landscape.
Desert Hiking
Beyond the Gunlock Falls trail, informal paths wind through the surrounding landscape. Exploration opportunities abound for those comfortable with off-trail desert hiking. Always carry plenty of water, a map, and let someone know your plans.
The terrain includes slickrock areas perfect for scrambling, hidden canyons waiting to be discovered, and ridge lines offering panoramic views. The remote nature means you might not see another person for hours.
Stargazing
Distance from city lights makes Gunlock Reservoir an excellent stargazing location. The clear desert air and dark skies reveal thousands of stars invisible from urban areas. The Milky Way stretches brilliantly overhead on moonless nights.
Winter offers the longest nights for stargazing. The cool temperatures remain comfortable with proper layering. Summer nights stay warm but provide shorter darkness windows.
Travel With Children
Gunlock Reservoir works well for family adventures with some planning and precautions. The mild climate and variety of activities appeal to children of different ages.
Child-Friendly Activities
The reservoir’s swimming areas provide safe water play for children. Shallow coves along the shoreline let kids splash and explore without deep water dangers. Always supervise children closely near water.
Fishing from shore teaches patience and provides excitement when kids catch their first bluegill. Simple pole-and-bobber setups work perfectly. Bring snacks and be prepared for short attention spans.
Easy walks along the shoreline let younger children experience the outdoors without challenging hikes. Rock hopping and exploring tide pools keep kids engaged. The Gunlock Falls trail suits older children and teenagers comfortable with moderate hiking.
Safety Considerations
The desert environment requires extra precautions when traveling with children. Heat poses the primary concern. Plan outdoor activities for early morning or late afternoon. Take frequent breaks in shade.
Children dehydrate faster than adults. Bring more water than seems necessary. Offer drinks regularly even if kids do not request them. Electrolyte drinks help maintain hydration during hot weather.
Sun protection is critical. Apply high-SPF sunscreen frequently. Dress children in light-colored, long-sleeved clothing. Wide-brimmed hats protect faces and necks. Sunglasses shield eyes from intense desert glare.
Essential for Kids: Water, sunscreen, hats, snacks, first aid supplies, life jackets for water activities, and a backup plan if children tire or heat becomes excessive.
Camping With Children
The primitive campsites at Gunlock State Park suit families seeking adventure. The lack of facilities makes it feel like real camping. However, be prepared for rustic conditions.
Bring entertainment for downtime. Cards, simple games, and stargazing activities work well. The campfire provides natural entertainment once the sun sets. Teaching kids about camping skills creates lasting memories.
Money Saving Tips
Gunlock Reservoir ranks as one of Utah’s most affordable outdoor destinations. Smart planning stretches your budget even further.
Park Fees and Passes
Daily entry costs $10 per vehicle. Frequent visitors should consider the $75 annual Utah State Parks pass. The pass provides unlimited access to all state parks. It pays for itself after eight visits.
Camping fees of $15 per night remain significantly cheaper than hotel accommodations. Multi-day camping trips offer excellent value. Water activities have no additional fees beyond the initial park entry or camping fee.
Food and Supplies
Pack food from home rather than buying supplies at convenience stores along the way. St. George grocery stores offer competitive prices. Stock up before heading to the reservoir.
Bring reusable water containers and fill them before leaving town. Buying bottled water at the small Gunlock store costs more than larger retailers. A large cooler keeps food and drinks cold throughout the day.
Equipment
Renting outdoor equipment in St. George before your visit costs less than specialized outfitters at major parks. Call ahead to compare prices. Better yet, borrow equipment from friends if possible.
Off-season visits reduce costs further. Spring and fall offer excellent weather with fewer crowds. Winter camping provides ultimate solitude at regular rates when most campgrounds elsewhere have closed or raised prices.
Free Activities
Many activities at Gunlock Reservoir cost nothing beyond park entry. Hiking, wildlife watching, photography, swimming, and exploring are all free. Shore fishing only requires a license, which is cheaper than guided fishing trips.
Safety, Etiquette & Local Customs
Understanding safety protocols and local etiquette ensures an enjoyable visit while protecting the environment.
Desert Safety
Heat exhaustion and dehydration pose the greatest risks at Gunlock. Drink water constantly, even when not thirsty. Signs of dehydration include headache, dizziness, and dark urine. Seek shade immediately if you feel unwell.
Flash floods can occur during thunderstorms, even miles away. Avoid camping or parking in dry washes. If thunder rumbles, leave canyon bottoms and seek higher ground.
Rattlesnakes inhabit the area. Watch where you place hands and feet when scrambling on rocks. Most snakes flee when they detect vibrations. Make noise while hiking to avoid surprising them.
Water Safety
Wear life jackets when boating, especially children and weak swimmers. Desert water feels refreshing but remains unforgiving. Swim only in designated areas where conditions allow safe entry and exit.
Water levels fluctuate throughout the year. Submerged rocks and hazards may lurk beneath the surface. Boat slowly in unfamiliar areas.
Leave No Trace Principles
Pack out everything you pack in. No trash facilities exist at most recreation areas. Bring garbage bags and leave sites cleaner than you found them.
Campfires are permitted in provided fire rings. Use dead and downed wood only. Never cut live vegetation. Extinguish fires completely before leaving or sleeping.
Human waste disposal requires care. Use vault toilets where provided. In undeveloped areas, dig catholes 15-20 centimeters (6-8 inches) deep and at least 60 meters (200 feet) from water sources.
Local Customs
The surrounding region has conservative values reflecting its Mormon heritage. Modest dress and respectful behavior are appreciated, though not required at outdoor recreation sites.
Sunday sees reduced business hours in St. George. Some restaurants and shops close. Plan accordingly if visiting on weekends.
The area remains relatively quiet and peaceful. Respect others seeking natural experiences. Keep noise levels reasonable, especially in camping areas after dark.
Visitor Comments About Gunlock Reservoir
“Gunlock Reservoir exceeded every expectation. The water was incredibly clear and the red rock scenery took my breath away. We spent three days camping and barely saw another soul. It felt like having a private desert oasis. The fishing was fantastic too – caught several largemouth bass right from shore. This place deserves far more recognition than it gets.”
“My family discovered Gunlock while staying in St. George. What a hidden gem! The kids loved swimming in the calm coves and we all enjoyed the hike to Gunlock Falls. The trail was moderately challenging but manageable for our teenagers. Seeing the waterfall flowing through that red rock canyon was magical. We will definitely return next year and plan to try kayaking.”
“As a photographer, Gunlock Reservoir provided endless inspiration. The way the morning light hits those red cliffs reflecting in the blue water creates incredible compositions. I visited in April when wildflowers were blooming and the weather was perfect. Spent four days exploring different vantage points and trails. The solitude and natural beauty here rival much more famous locations in Utah. Highly recommended for anyone seeking authentic desert landscapes without the crowds.”
