Trail terms

Backcountry

Also called back country

What does backcountry mean?

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.

What is the difference between backcountry and frontcountry?

Whether you can drive to it. The National Park Service describes most camping in parks as frontcountry camping, where visitors drive to an established campground, and calls it car camping. Backcountry is everything past that: trails, remote campsites and water routes you reach under your own power.

The difference shows up in what you are responsible for. Nothing is waiting for you out there, so shelter, water treatment and a plan for waste all travel with you, and the Park Service asks backcountry visitors to follow Leave No Trace principles to protect the plants and animals that live there.

Do you need a permit for the backcountry?

For overnight trips in many national parks, yes. Grand Canyon National Park is a clear example: it requires a backcountry permit for overnight camping outside its developed campgrounds, and states that day hikes, including hikes at night, do not need one.

Rules are set park by park and forest by forest, so check the land manager's own page before a trip. The Park Service's general advice for backcountry camping is to find out ahead of time about any permits and park regulations that apply.

Is backcountry the same as Wilderness?

No. Backcountry is a description; Wilderness, with a capital W, is a legal designation. The Wilderness Act of 1964 defines it as an area where the earth and its community of life are untrammeled by man, of at least 5,000 acres or large enough to protect, and bars motor vehicles, motorized equipment and other mechanical transport inside it, with limited exceptions.

Plenty of backcountry is not designated Wilderness, and the difference matters mostly for what you can bring. A mountain bike that is allowed on one backcountry trail can be prohibited once the same trail enters a Wilderness area.

What this means when you're choosing

  • Whether your trip needs a permit, and how far ahead the land manager releases them
  • A way to call for help where there is no cell coverage, such as a satellite messenger
  • Water treatment, since backcountry sources are untreated
  • The food storage rule for that area, which can require a specific bear canister

The common mistake

Assuming a GPS watch or phone can call for help

A watch or phone that shows your position cannot send an SOS where there is no cell signal. If you want to be able to summon help from the backcountry, that takes a satellite messenger, a personal locator beacon or a phone with built-in satellite SOS.

Common questions

What counts as backcountry camping?

Camping away from developed, drive-in campgrounds, at a site you reach on foot or by water. The National Park Service's examples include backpacking, water trips on rafts, canoes or boats, and climbing.

Do you need a permit to day hike in the backcountry?

It depends on the park. Grand Canyon, for example, requires a backcountry permit for overnight camping outside its developed campgrounds but not for day hikes. Check the specific park or forest before you go.

Where this is defined

More in trail terms

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.

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.

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.
