Adventures · On foot for a week, with everything you need on your back or a horse
Multi-day trek
A trek is a walk that lasts longer than your legs expected, through country that a road does not reach. It is the cheapest way to see the most, and it is the adventure where training and packing weight decide the outcome.
Trekking is travel at three kilometres an hour, which is the speed at which a landscape has time to change you. The places on this site that ask for it are chosen for their trails as much as their views: the W and O circuits in Torres del Paine, the Laugavegur across Iceland’s interior, the Jomolhari route in Bhutan and the Markha valley in Ladakh, the Kalsoy and Slættaratindur walks in the Faroes, the via ferrata across the Tsingy.
What it asks of the body
Six hours of walking a day with a pack, on consecutive days, on ground that goes up and down more than the map suggests. The Stage Simulator turns distance, ascent and terrain into hours and calories, and the answer is usually longer than the guidebook. The legs adapt within days; the feet and the knees are where treks fail, and the Training Simulator’s twelve weeks are aimed at them.
What it asks of the calendar
Trails have seasons that are set by snow, monsoon and daylight, and the windows are short: ten weeks in the Icelandic highlands, four months in Patagonia, two windows either side of the monsoon in Bhutan. Huts and permits sell out months ahead in the good windows. The plan that works books the beds first and the flights second.
What it costs
The walking is free and the country is usually cheap; the refugios, the permits and the crews are the cost. Torres del Paine on refugios sits in the mid band, the Laugavegur on huts in the low band with a tent, Bhutan in the high band by law. The Budget Simulator has the numbers per place.
Essentials
- Boots broken in over fifty kilometres before the trip
- Poles, which save the knees on every descent
- A shell that is actually waterproof and a warm layer that packs small
- A sleeping bag rated for the coldest night on the itinerary, not the average
- A pack under twelve kilos with water, or you will hate day three
Risks
- ▲▲WeatherWind and rain at altitude cause hypothermia in summer; the shell and the turn-around decision are the protection.
- ▲▲Knees and feetBlisters and descents end more treks than fitness does; tape the hot spots early and use the poles.
- ▲▲AltitudeAbove 3,000 m the Altitude Simulator rules apply; treks that gain height too fast are the ones the clinics see.
- ▲▲NavigationMarked trails are marked until the fog; a map, a phone with the offline route and a turn-back rule.
Questions people ask
How fit do I need to be?
Able to walk six hours with a pack on consecutive days and recover overnight. That is a training goal for most people, reachable in twelve weeks from an ordinary base.
Guided or independent?
Torres del Paine and the Laugavegur have marked trails and staffed huts. Bhutan and Ladakh’s longer treks run with crews by law or by sense. The guide buys logistics, safety and pace.
How heavy should the pack be?
Under twelve kilos with a litre of water for hut-to-hut, under sixteen when carrying a tent and food. The Pack Simulator adds it up and tells you where the weight went.
