Some walks take an afternoon. These ones take a season, and they change how you think about walking.
A long-distance trail is not simply a longer day hike. It is a project with a season, a budget, a resupply strategy and a real chance of failure — most thru-hike attempts on the big American trails end before the finish, usually for reasons that have nothing to do with fitness. This guide covers the trails worth considering in 2026, what each one demands and how to plan one without romanticising the logistics.
If you are only asking which is the longest, the answer is the Great Trail in Canada, formerly the Trans Canada Trail, a connected network stretching over 28,000 km across the country. It is a multi-use network rather than a continuous wilderness footpath, which makes it a different proposition from a classic thru-hike, but it is the longest recreational trail system on the planet by a wide margin.
The trails worth building a season around
In the United States, the Triple Crown still defines the category. The Appalachian Trail runs about 3,540 km through eastern forest with a relentless profile and a strong social culture. The Pacific Crest Trail covers roughly 4,265 km of desert, Sierra and Cascade terrain with a demanding snow-timing problem in the middle. The Continental Divide Trail is the wildest of the three at about 4,990 km, with route choices, navigation demands and long carries.
Elsewhere, the Te Araroa crosses New Zealand end to end for around 3,000 km with river crossings that define its difficulty. Europe offers the GR20 in Corsica for a brutal fortnight, the Via Alpina and the E-paths for hut-supported months, and the Camino de Santiago for a walk that is as much cultural as physical. In Japan, the Michinoku Coastal Trail runs about 1,000 km along the Tohoku coast and remains extraordinarily under-walked.
Seasons and timing: the constraint that outranks everything
Every long trail has a weather window, and missing it is the most common reason attempts fail. Northbound Appalachian Trail hikers typically start in March or April; Pacific Crest Trail hikers start in April and race snowmelt into the Sierra; Continental Divide Trail hikers usually start in April going north or in June going south. In the southern hemisphere, Te Araroa runs from October to March. Build the schedule around the mountains, not around your holiday allowance.
Budget, resupply and the boring parts that decide the outcome
Plan for roughly $1,000 to $1,500 per month on a long American trail once you include town food, accommodation, transport and gear replacement, plus the gear you buy before starting. Resupply happens in three ways — buying as you go in trail towns, mailing yourself boxes to post offices and hostels, or a hybrid, which is what most experienced hikers end up doing. Bounce boxes, permit paperwork and a plan for foot problems are unglamorous and decisive.
Why people quit, and how to not be one of them
The common causes are injury, money, homesickness and the simple realisation that walking all day for months is not what someone expected. Overuse injuries dominate, and nearly all of them come from doing too many miles too early. Start slowly for the first two weeks — 15 to 20 km days rather than 40 — take zero days before you think you need them, and treat feet as maintenance equipment. The hikers who finish are rarely the fastest ones in week one.

Preparing your body and your gear for months of walking
Physical preparation should start about four months out with progressive loaded walking rather than gym work. Build to back-to-back long days at weekends with your intended pack weight, because the specific adaptation you need is tolerance of consecutive days, not peak fitness on any one of them. Strength work for hips, calves and feet reduces the overuse injuries that end most attempts.
Gear philosophy on long trails converges on the same conclusions. Base weight below 9 kg makes a large difference to injury risk. Trail shoes replace boots for most hikers, worn out and replaced every 600 to 800 km. Sleep systems matter more than tents, since sleep quality determines recovery. And every item you carry should be used at least once a day, or it is a passenger.
Consider a section hike before committing a whole season. Two weeks on a long trail teaches you more about your systems, pace and appetite for the lifestyle than six months of planning. Many people discover that what they actually wanted was three weeks of hut-to-hut walking in the Alps rather than five months of resupply logistics in the American West, and that is a legitimate and excellent outcome.
Solo hiking on long trails
Long trails are among the safer places to hike alone because you are rarely truly alone for long, but solo travel still demands discipline: a satellite communicator, a shared itinerary, conservative decisions on river crossings and snow, and a willingness to turn around. The best solo hikers are not the boldest; they are the ones who consistently choose the boring option when conditions are marginal.
Geo guide: long trails by continent
A quick orientation to where the world’s best long-distance walking sits.
- North America — The Triple Crown trails plus regional gems such as the Long Trail, Colorado Trail and Great Divide Trail in Canada.
- Europe — Hut-supported alpine routes, the GR network in France, the Camino in Spain and the long E-paths across the continent.
- Oceania — Te Araroa in New Zealand and the Bibbulmun Track in Western Australia, both with excellent hut and shelter systems.
- Asia — The Michinoku Coastal Trail and Shikoku pilgrimage in Japan, plus the Great Himalaya Trail for high-altitude expeditions.
- South America — Long linear routes are scarce; most classic hiking is multi-day circuits such as Torres del Paine and Huayhuash.
Conditions change fast in the mountains: always check the local land-manager forecast before you leave the trailhead.
Frequently Asked Questions
What is the longest hiking trail in the world?
The Great Trail in Canada, formerly the Trans Canada Trail, is the longest recreational trail network at over 28,000 km, though it is multi-use and not a continuous wilderness footpath like a classic thru-hike.
How much does it cost to thru-hike a long trail?
Budget roughly $1,000 to $1,500 per month on a major American trail, plus initial gear. Town stops, not trail days, are what consume a thru-hiking budget.
Which long-distance trail is best for beginners?
The Camino de Santiago, the Bibbulmun Track or a two-week section of the Appalachian Trail all offer a genuine long-distance experience with regular resupply and low navigational demands.
How long does it take to hike a long-distance trail?
Roughly five to six months for the Pacific Crest or Appalachian trails at typical paces, four to five months for Te Araroa, and around two weeks for shorter classics such as the GR20.
Do I need to be very fit to start a thru-hike?
You need enough fitness to walk 15 to 20 km a day comfortably at the start. The trail builds the rest, provided you resist the urge to hike big miles in the first fortnight, which is when most injuries begin.
