International Trek Packs: Complete Guide

Most Camino walkers carry 20 to 30 liters, because you sleep in albergues and hostels rather than a tent, and villages resupply food and water daily. That removes the shelter, sleep system, and multi-day food that force a bigger pack elsewhere. A loaded Camino pack should stay near 10% of body weight, so a light 30-liter pack with a real hipbelt, worn correctly, is the standard. Walkers who send a bag ahead each day use an even smaller daypack. See how to size a pack to your torso before you choose a Camino pack.

Hut-to-hut routes like the Tour du Mont Blanc reward a 30 to 40 liter pack, because the mountain refuges provide beds, blankets, and meals, so you leave the tent, sleeping bag, and stove at home. What you do carry is layered mountain clothing, rain protection, water, snacks, and a light sleeping-bag liner huts often require. A ventilated 35-liter pack with a stable hipbelt and good rain cover suits most TMB and alpine hut circuits. The hut-to-hut activity guide covers what to leave behind on serviced routes.

Kilimanjaro and the Everest Base Camp trek are portered treks, so you carry only a daypack while a porter or yak moves your main kit in a duffel. On Kilimanjaro, operators cap the porter duffel weight (commonly around 15 kg / 33 lb including the bag), and you carry a 25 to 35 liter daypack with water, layers, sun protection, snacks, and camera. Everest Base Camp works the same way: a 30 to 40 liter daypack for the day, a soft duffel for the porter. Rigid-frame packs are the wrong tool for the duffel; a soft, lockable duffel is what these treks want.

Getting to a trek matters as much as the trek itself, so many international hikers choose a travel-friendly pack that meets carry-on limits and hides its straps for flights. A panel-loading 35 to 45 liter pack with a stowable harness travels as a carry-on and still carries like a hiking pack on trail. The travel-hiking activity guide covers convertible packs and carry-on compliance in depth.

Trek pack sizes at a glance

Across every route the rule is the same: size the pack to what you carry on your back, not to the whole trip, and confirm your operator's porter or duffel rules before you buy.
