Should I bring a tent?

Only if you plan on camping off-grid. Many popular routes, like the W Trek in Torres del Paine, have 'refugios' where you can sleep indoors, saving you the weight of a tent and stove.

Is it safe to leave my gear in hostels?

Yes, but always bring a sturdy steel-cable lock to secure your pack to the bed frame or a locker if you are leaving it behind for a day trip.

How do I handle fuel for my stove?

Do not pack fuel cans. They are prohibited on flights. Buy your fuel canisters at outdoor shops in major gateway cities like Santiago, Cusco, or Bariloche.

How to Pack Trekking Gear for South America

Prioritize a modular layering system and ensure all gear fits in a 50-60 liter internal frame pack to avoid airline baggage issues. Protect all electronics and sleeping gear in waterproof dry bags, as weather conditions in the Andes and Patagonia can shift from sunshine to driving rain in minutes.

Select the right pack size. Use a 50-60 liter pack. Anything larger will be too heavy for regional airline weight limits and cumbersome on crowded local buses.
Implement the layering system. Pack a moisture-wicking base layer, a merino wool mid-layer, a lightweight down jacket, and a high-quality hardshell rain jacket. Skip heavy cotton entirely.
Waterproof everything. Do not rely on a pack cover alone. Use individual dry bags for your sleeping bag, extra clothes, and electronics to ensure they stay dry during river crossings or heavy downpours.
Optimize footwear. Wear your heavy hiking boots on the plane to save weight and space. Pack lightweight camp shoes or sandals for evenings to give your feet a break.
Distribute weight. Place your sleeping bag at the bottom, heavy items (food, water, fuel) close to your back in the middle, and light items at the top and in side pockets.
