Do I need a walking pole?

Yes. The Andes are steep and the ground is often loose scree. Trekking poles save your knees on long descents and provide essential balance.

How do I keep my electronics from dying in the cold?

The cold drains batteries fast. Keep your phone and camera batteries in an inside pocket close to your body heat, and sleep with them in your sleeping bag at night.

Is bottled water available on the trail?

No. Bring a reliable water filtration system, like a Sawyer Squeeze or chlorine dioxide tablets, to treat stream water.

How to Pack for High-Altitude Hiking in the Andes

Prioritize a strict layering system to handle temperature swings that range from -5°C at night to 20°C in the sun. Pack specialized gear to manage the intense UV exposure and rapid weather shifts common above 3,500 meters.

Master the three-layer rule. Wear a moisture-wicking base layer (merino wool), a mid-layer for insulation (down or synthetic puffy jacket), and a waterproof, windproof shell. Do not bring cotton, as it stays wet and causes hypothermia.
Select footwear for stability. Wear broken-in, waterproof mid-cut hiking boots. Ensure they have ankle support for uneven, rocky Andean trails and enough room to wear two pairs of socks—one thin liner, one thick wool layer—to prevent blisters.
Pack for high-altitude sun. The sun is significantly stronger at high altitude. Pack high-SPF sunscreen (50+), polarized sunglasses with side protection, and a wide-brimmed hat. Your skin will burn in minutes without these.
Optimize your daypack. Use a 20-30 liter pack with a rain cover. Keep your water bladder (minimum 2 liters) and high-calorie snacks (nuts, dried fruit) accessible so you don't have to stop and take your pack off constantly.
