Long-Distance Hiking vs Thru-Hiking vs Trekking: What’s the Difference?

Long-distance hiking is the umbrella term: any multi-day walk on a long, established route. A thru-hike is more specific: walking one named trail from end to end in one continuous trip, ideally within a single season. Trekking usually means multi-day walking in mountainous, remote or international terrain, often hut-to-hut or otherwise supported.

That is the clean version. The honest version is that these words overlap heavily, shift by country, and are used inconsistently by walkers, guidebooks and outfitters.

I’ve walked routes that could fairly wear all three labels, and I’ve stopped worrying too much about which badge they deserve. The useful question is not “what is this called?” but “what kind of trip am I actually planning?”

Quick definitions: read this and you’re 90% there

• Long-distance hiking: Any walk that takes more than a single day on a long, established route, whether you do it all at once or in separate stages.
• Thru-hike: Walking an entire established long-distance trail from one end to the other continuously, ideally within a single season.
• Trekking: A multi-day, long-distance walk, usually in remote or mountainous terrain, often more strenuous and frequently supported.

Long-distance hiking: the umbrella term

Long-distance hiking is the broadest and safest phrase of the three. If you are walking for more than a day on a long, established route, you are in long-distance hiking territory — whether you carry everything from camp to camp, stay in villages and huts, or do the route in one go or over years.

There is no single official, universal definition of how long a hike must be before it “counts” as long-distance. One common yardstick comes from the UK’s Long Distance Walkers Association, which defines a long-distance path as a route of about 20 miles (32 km) or more and mainly off-road. Treat that as a helpful rule of thumb, not a law handed down on stone tablets.

In Britain and Europe, the phrase often lives alongside “long-distance path”. In England and Wales, the flagship long-distance paths are the National Trails, waymarked with a distinctive acorn symbol and managed to quality standards. Scotland has Scotland’s Great Trails: long-distance routes intended to be tackled over several days, either as a string of day trips or as an end-to-end expedition.

If you want the deeper version, we have a full guide to what is a long-distance hike. For this article, the key point is simple: long-distance hiking describes the broad activity, not one exact style. You can do it continuously or in sections, carrying your own kit or using huts, accommodation, baggage transfer, guides or porters where that style exists.

So when in doubt, “long-distance hike” is the least fussy term. Nobody sensible will correct you for using it.

Thru-hiking: end to end, in one go

A thru-hike — also spelled “through-hike” — means walking an entire established long-distance trail from one end to the other, continuously, ideally within a single season. The person doing it is a thru-hiker.

This is where the language gets more specific. Thru-hiking is not mainly about mountains, remoteness or camping. It is about how you tackle a route: in one continuous push rather than in pieces.

Thru-hike vs section hike

This distinction comes up constantly in long-distance walking circles, so it is worth learning. Same route, different method:

• Thru-hike: One named trail, end to end, in one continuous trip.
• Section hike: The same whole trail, completed in separate sections over multiple trips, across months or years.

Neither is morally superior. A thru-hike asks for a block of time and a certain tolerance for momentum, weather and logistics. A section hike can be more realistic for people with jobs, families, limited leave or a perfectly healthy dislike of rushing.

The word “thru-hike” has a strong North American origin and flavour. It is bound up with the long American trails, especially the Appalachian Trail and the Pacific Crest Trail. Earl Shaffer is credited with the first claimed thru-hike of the Appalachian Trail in 1948 — and tellingly, the trail was not originally designed to be walked end to end; that idea came later.

But while the word is American, the act is not. You can thru-hike a British National Trail or a European route just as much as an American one. The Pennine Way, for example, is a 431 km point-to-point National Trail in England, taking about 16–19 days and rated Strenuous — a classic British trail to thru-hike end to end: long, tough and largely upland or moorland in character.

If the end-to-end idea appeals, browsing epic thru-hikes shows how the term is used in practice. Just remember: thru-hiking describes the commitment to a continuous finish, not a particular landscape.

Trekking: multi-day walking in big or remote country

Trekking is a multi-day, long-distance walk, usually in remote and/or mountainous terrain. It often feels more expeditionary than an ordinary hike, and it is frequently supported: hut-to-hut in the Alps, teahouse-to-teahouse in Nepal, or camping with a guide and porters.

The word carries a sense of effort. A trek is rarely sold as a quick stroll after lunch; it suggests several days, serious terrain, fewer roads, and at least a whiff of self-reliance or organised support. That support is part of the texture of many treks. On hut-to-hut treks, the walking may be hard, but you are moving between places built into the rhythm of the route; in other regions, support might mean teahouses, guides, porters or camps.

The textbook HikeList example is the Tour du Mont Blanc. It is a 170 km alpine loop around the Mont Blanc massif through France, Italy and Switzerland. The classic itinerary is about 11 days, it is rated Hard, has roughly 10,000 m of total ascent, and is a well-waymarked hut-to-hut trek. It was also the first international GR, or grande randonnée, route.

Why “trek” feels bigger than “hike”

A short word-history detour, because it actually helps. “Trek” comes from Afrikaans, the South African language descended from Dutch, and ultimately from Dutch “trekken”, meaning to march or journey, originally “to draw” or “to pull”. In 19th-century South Africa, a trek meant one day’s stage of an overland journey by ox-cart, associated with the Groot Trek migration from 1835. By around 1941 the word had entered general English as a noun meaning a long or toilsome journey or expedition.

That history explains why “trek” still sounds like more of an undertaking than “walk”. You go for a walk to clear your head; a trek implies you may need to clear your diary.

British, American and international usage

This is where some of the confusion comes from.

British and European walkers use “trekking” freely for multi-day mountain trips in places such as the Alps, the Pyrenees, the Dolomites and the Himalaya. Americans more often say “backpacking” for the carry-your-own-gear version, and “thru-hike” for the end-to-end version. They may use “trek” too, but often more loosely or casually.

Likewise, “long-distance path” and “National Trail” are very British and European phrases. Americans more often say “long trail” or simply name the trail.

So if someone asks “is trekking the same as hiking?”, the answer is: sometimes, but not exactly. Trekking is a kind of hiking in broad terms, but it usually points to a bigger, more remote, more mountainous or more supported multi-day journey.

So how do they overlap?

This is the part that makes the whole debate less tidy and more useful. Long-distance hiking, thru-hiking and trekking are not rival boxes on a form. They describe different aspects of a trip: long-distance hiking is the broad category, thru-hiking is about doing a whole named route continuously, and trekking is about the feel and setting. So a single route can wear more than one label at once.

The Tour du Mont Blanc is a trek and a long-distance hike. If you walk its 170 km loop continuously, it is also loosely a thru-hike, although many people would still simply call it a trek because of its alpine, hut-to-hut character.

The Appalachian Trail is a long-distance hike that people thru-hike. Much of its terrain is mostly forested, so few people would call it classic “trekking” country, even though an end-to-end walk is obviously a major undertaking.

A Camino de Santiago route is a long-distance hike and a pilgrimage. The Camino is a network of pilgrimage routes across Spain, and into France and Portugal, ending at Santiago de Compostela. It is generally gentle, low-lying and cultural rather than mountainous, so people rarely call it a trek; “thru-hike” is increasingly used for walking a route end to end.

If that kind of journey appeals, our collection of pilgrimage trails is the better mental shelf than “treks”. And if you keep meeting other terms while planning — section hiker, supported, self-guided, hut-to-hut — our long-distance hiking glossary will save you a few rabbit holes.

A side-by-side comparison

Here is the clean comparison. Keep it handy, but do not treat it as a court ruling; real trips often blur the edges.

Term	What it means	Typical length	Typical terrain & support	Example
Long-distance hiking	The umbrella term for a walk of more than one day on a long, established route	More than a single day; no universal minimum, though the LDWA uses about 20 miles (32 km) or more as one rule of thumb	Can be done all at once or in stages; terrain and support vary	National Trails in England and Wales; Scotland’s Great Trails
Thru-hike	Walking an entire established long-distance trail from one end to the other continuously	The full named trail, ideally within a single season	Any terrain; the key point is end-to-end continuity, not landscape	The Pennine Way as a 431 km point-to-point National Trail walked end to end
Trekking	A multi-day long-distance walk, usually in remote and/or mountainous terrain	Multi-day	Often strenuous; frequently supported, such as hut-to-hut, teahouse-to-teahouse, or with a guide and porters	The Tour du Mont Blanc, a 170 km alpine hut-to-hut loop

Which word should a beginner use?

Use the word that helps you find the right information. That sounds obvious, but it cuts through a lot of unnecessary trail-forum fog.

If you just want a multi-day walk on a long trail, say long-distance hike. It is the safe umbrella term, and nobody will blink.

Say thru-hike when you specifically mean doing a named route end to end in one continuous trip. If you are doing it in separate blocks over time, say section hike instead.

Say trekking when you mean a mountainous, remote or far-flung multi-day walk, especially one that is supported, guided, hut-to-hut or abroad. If you are talking to Americans, do not be surprised when they say “backpacking” where a British or European walker might say “trekking”. And if more than one of these fits your trip? Good — that is completely normal.

The labels are loose. Guidebooks disagree, outfitters disagree, and walkers from different countries use different words with total confidence. In my experience, the people having the best time are usually the ones who picked the right route, packed sensibly, and stopped worrying about the taxonomy.

If you are at the “which trip is right for me?” stage, read how to choose your first long-distance hike next. Pick the route, not the word; the walking is the same either way.
