Trail terms

Section hiking

Also called section hike

What is section hiking?

Section hiking is completing a long trail in pieces, one stretch at a time over separate trips, rather than in one continuous push. The Appalachian Trail Conservancy counts anyone who finishes the whole trail in more than 12 months as a section hiker, and recognizes them as 2,000-milers alongside thru-hikers.

How is section hiking different from thru-hiking?

It is the same trail on a different clock. The Appalachian Trail Conservancy defines a thru-hike as the entire trail in 12 months or less, whether northbound, southbound or as a flip-flop, and a section hike as the entire trail in more than 12 months. Both finish as 2,000-milers.

The Conservancy notes that some section hikers finish in two or three summers and others over a decade or more. For 2025 it reported 116 section-hike completions of the whole trail.

Does a section hike need a different permit?

Sometimes, and the Pacific Crest Trail is the example to know. Its long-distance permit is for people traveling more than 500 continuous miles in a single trip. North Cascades National Park counts anyone doing less than that, or more than one PCT trip in a year, as a section hiker who needs a park-issued backcountry permit to camp inside the park.

So a section hiker usually builds a trip from the local permits for whichever parks and forests that stretch crosses, the same way any backpacker planning that route would. Check each land manager's rules for the specific section and year.

Why do people section hike?

Time, mostly. A thru-hike of a long trail takes months, and few people can step away from work and family for that long. Section hiking turns the same goal into a series of weekends, weeks or summers.

It changes the planning more than the gear. Each trip starts and ends at a trailhead you have to reach and leave, so transport and permits take up much of the planning, and the length of each section, rather than a resupply schedule, sets how much food the pack carries.

What this means when you're choosing

  • Transport to and from each trailhead, planned before the permits
  • Permits for every park and forest the section crosses, since a long-distance permit may not apply
  • Section length matched to the food you can carry between trailheads
  • A record of the miles you complete, if you intend to report the whole trail at the end

Which to pick: Same trail and the same finish: a section hike trades one long journey for trips that fit around the rest of your life.

The common mistake

Assuming a thru-hiker's permit rules apply to your section

Long-distance permits are built for long, continuous trips. On the PCT, a section under 500 miles means arranging the permits each park and forest along it requires, and North Cascades National Park, for one, asks section hikers for a park backcountry permit obtained in advance.

Common questions

Does a section hike count as completing the Appalachian Trail?

Yes. The Appalachian Trail Conservancy recognizes section hikers who complete the entire trail as 2,000-milers, the same as thru-hikers. The two are told apart only by whether the whole trail took more or less than 12 months.

How long does it take to section hike a long trail?

As long as you like. The Conservancy notes that some section hikers finish the A.T. in two or three summers and others take a decade or more.

Base weight

Base weight is everything in your pack except food, water and fuel: the gear that doesn't get used up. It's the number backpackers compare, because consumables vary with trip length while base weight is a property of your kit.

Ultralight

Ultralight is a style of backpacking built around a base weight under 10 lb. It gets there by making the big three lighter and by carrying fewer things, which trades comfort in camp and margin in bad conditions for comfort while walking.

Fastpacking

Fastpacking is covering a multi-day route with a pack light enough to run in, somewhere between trail running and ultralight backpacking. Typical loads run 8 to 20 liters, and the trip is usually run downhill and on the flat and hiked uphill.

Thru-hiking

Thru-hiking is walking a long trail end to end in one continuous trip, usually within a single season. The Appalachian Trail, Pacific Crest Trail and Continental Divide Trail are the best-known examples in the US, each taking several months.

Shoulder season

The shoulder seasons are spring and autumn, the months either side of settled summer conditions. Days can be warm and nights near freezing, weather changes faster, and gear that works in July is often not enough in late September.

Three-season

Three-season gear is built for spring, summer and autumn but not sustained winter conditions. It's the default rating for most backpacking equipment, and in practice it means handling rain, wind and light frost but not deep snow.

Layering system

A layering system is the practice of combining a moisture-moving base layer, an insulating mid layer and a protective shell, so you can regulate temperature by adding and removing pieces rather than relying on one heavy garment.

Zero day

A zero day is a day on a long trail where you walk no trail miles at all, usually taken in a town to rest, resupply and deal with logistics. A nero is a near-zero: a handful of miles into or out of town with the rest of the day off.

Cowboy camping

Cowboy camping is sleeping outside with no shelter over you: a pad, a bag or quilt, and the sky. It saves the weight and the time of pitching a tent, and it trades away protection from rain, wind, dew, insects and anything that walks past in the night.

Postholing

Postholing is breaking through soft snow with each step and sinking to your shin, knee or thigh, leaving a line of holes behind you. It is exhausting, it can drop your pace to under a mile an hour, and it damages the trail for everyone following.

Slickrock

Slickrock is bare, exposed sandstone with no soil on it and no tread cut into it. You walk on the rock itself and follow cairns rather than a path. Dry sandstone gives excellent grip; wet or dusty sandstone gives very little, which is where the name misleads people.

Trailhead

A trailhead is the designated access point where a trail begins, and usually where you park and start walking. Many have a map board, signs or a toilet. The US Forest Service draws a firm line: a plain junction of two trails, or of a trail and a road, is not a trailhead.

Treeline

Treeline is the elevation, or latitude, above which trees can no longer grow. It is less a line than a zone where trees shrink into stunted, wind-shaped growth, and it sits at very different heights: between 5,000 and 6,000 feet in Washington's Olympics, and above 10,000 in the Sierra.

Backcountry

Backcountry is undeveloped land away from roads and drive-in campgrounds, reached on foot or by water. In US parks it is the opposite of frontcountry, where you drive to a campground, and camping there often needs a permit. It is not the same as legally designated Wilderness.

Big three

The big three are a backpacker's shelter, sleep system and pack: the three items where most of a kit's weight sits and, as REI puts it, where you can cut the most. The usual advice is to lighten the shelter and sleep system first and choose the pack last.
