Whether you're hiking the W or O circuits in Torres del Paine, trekking the legendary Inca Trail in Peru, or exploring remote gems like the Horquetas trail in Cerro Castillo, how you pack your backpack can make or break your experience.
On South American treks you'll meet rain, wind, heat, snow and long distances — sometimes in a single day. The ABCDE method is a simple way to pack smart: keeping your load balanced, organized and ready for anything.
Anything you need frequently during the day should be easy to reach without unpacking everything: water or a hydration bladder, snacks, a rain jacket or windbreaker, sun protection (hat, sunglasses, sunscreen) and your map, GPS or printed itinerary.
Distribute weight evenly so the pack feels stable. Heavy items like food, stove and tent go centered and close to your back; softer, lighter gear like clothing goes toward the outside. Avoid loading one side more than the other — on long treks like the O Circuit, balance prevents injuries and fatigue.
Pack everything tight to avoid bulk and shifting. Use compression sacks for your sleeping bag and clothing, roll gear into packing cubes or stuff sacks, and keep loose items off the outside (poles and a sleeping mat are the usual exceptions). On steep trails like the Inca Trail, a compact load means better mobility.
Rain, humidity and river crossings will find your gear. Line your pack with a waterproof liner, store clothes, sleeping bag and electronics in dry bags, and carry a rain cover even in summer. This matters most in wet, windy environments like Patagonia and the Horquetas trail.
Try to fit all your gear inside the pack rather than dangling it off the outside where it can snag, fall or throw off your balance. Clean packing improves performance and safety on remote, windy treks.
Packing isn't just *what* you bring — it's *how* you bring it. The ABCDE method keeps you safe, comfortable and efficient so you can focus on the trail. *Planning a trek? Explore our South America hiking trips.*
ABCDE stands for Accessible, Balanced, Compact, Dry and Everything Inside — a simple framework for packing a trekking backpack so it's organized, stable and weatherproof.
Keep heavy items (food, stove, tent) centered and close to your back, and lighter items like clothing toward the outside. Even weight distribution prevents back pain and keeps you balanced on uneven terrain.
Line your backpack with a waterproof liner, store your sleeping bag, clothes and electronics in dry bags, and use a rain cover — even in summer, since Patagonian weather changes fast.
Water, snacks, a rain or wind layer, sun protection and your map or itinerary should all be reachable without unpacking your whole bag.
