How much should my pack weigh for Andes hiking?

Keep pack weight to 15-20% of your body weight maximum. At altitude, even experienced hikers struggle with heavy packs. A 150-pound person should carry no more than 22-30 pounds including water.

What's the most important item for Andes travel?

Quality sunglasses rated for glacier conditions. UV exposure at altitude causes snow blindness and permanent eye damage. Bring a backup pair—losing sunglasses in the mountains is dangerous.

Should I pack for summer or winter in the Andes?

Pack for both. Mountain weather changes rapidly and temperatures vary 60°F+ from day to night even in summer. Always bring insulation and rain gear regardless of season.

Can I buy gear locally in Andean cities?

Major cities like Cusco, La Paz, and Quito have outdoor gear shops, but quality varies and prices are often higher than home. Rent technical items locally but bring personal items like base layers and boots.

How to Pack for Andes Mountain Travel

Pack in layers for extreme temperature swings, prioritize lightweight gear rated for altitude, and bring backup items for electronics and clothing since mountain weather changes fast. Your pack weight matters more at altitude—aim for 15-20% of your body weight maximum.

Choose your base layers. Pack 2-3 merino wool or synthetic base layers. Avoid cotton completely. Bring lightweight long underwear even for summer trips—temperatures drop 35°F for every 5,000 feet of elevation.
Add insulation layers. Pack a down or synthetic insulation jacket rated to at least 20°F below expected low temperatures. Fleece or wool mid-layers work for active warmth. Bring a lightweight backup insulation layer.
Select your shell layers. Pack a waterproof, breathable rain jacket and pants rated for mountain conditions. Look for pit zips and full-zip pants for ventilation. Weather changes in minutes in the Andes.
Pack altitude-specific items. Bring lip balm with SPF 30+, sunglasses rated for glacier conditions, and a wide-brimmed hat. UV exposure increases 10% for every 1,000 feet. Pack altitude sickness medication if going above 8,000 feet.
Prepare electronics for conditions. Bring extra batteries—cold drains them 50% faster. Pack a portable charger and keep electronics in inside pockets. Bring a headlamp with red light mode for camp use.
Add mountain-specific gear. Pack trekking poles for steep terrain, a buff or neck gaiter for wind protection, and gaiters to keep rocks and snow out of boots. Bring duct tape for quick gear repairs.
