From the turquoise marble caves of General Carrera Lake to the hanging glaciers of Queulat National Park, Aysen invites you to explore Earth’s last true frontier.

Best Time to Visit Aysen
Aysen’s weather can be unpredictable, with the local saying: “You can experience four seasons in a single day.” However, certain periods offer more reliable conditions for exploring this magnificent region.
| Season | Months | Weather | Recommendation |
| Summer (Peak) | December – February | 10-20°C (50-68°F), longer daylight hours | Ideal for hiking, kayaking, and all outdoor activities |
| Fall | March – May | 5-15°C (41-59°F), changing colors | Beautiful foliage, fewer tourists |
| Winter | June – August | 0-8°C (32-46°F), snow at higher elevations | Limited access to some areas, avoid unless seeking solitude |

Practical Travel Tips
Connectivity
Internet and cell service are limited throughout Aysen. Major towns like Coyhaique have reliable coverage, but expect to be offline in more remote areas. Download maps and essential information before departing, and consider renting a satellite phone for emergency communication if venturing into backcountry areas.
Money Matters
ATMs are available in larger towns like Coyhaique and Chile Chico, but can be unreliable or run out of cash. Bring sufficient Chilean pesos for your journey, especially when traveling to remote areas. Credit cards are accepted at larger establishments but not universally, so cash is essential.
Packing Essentials
Pack for all weather conditions, even in summer. Essential items include waterproof jacket and pants, layers for warmth, sturdy hiking boots, sun protection, and insect repellent. A good first aid kit is recommended, as medical facilities are limited outside major towns.
