Camping Glossary

Plain-English definitions for the camping terms beginners hear most.

B

Baseplate compass
A flat, see-through compass with a rectangular plate, used for taking bearings off a paper map. The orienteering standard for beginners. Compass basics.
Bear box
A metal locker provided at many campsites for storing food and scented items overnight. Use it where it exists — your cooler is not bear-proof.
Bearing
A direction expressed in degrees (0–360) from north. You take a bearing with a compass to head toward a known landmark. Compass basics.
Bivy
Short for "bivouac sack" — a single-person waterproof shell that goes over a sleeping bag. Lighter than a tent, but cramped.
BLM
Bureau of Land Management. Federal agency that manages 245 million acres of public land, much of which allows free dispersed camping. Dispersed camping guide.
Bowline
A fixed loop knot that holds under load and unties easily after. The classic "rabbit comes out of the hole" knot. Learn the knot.

C

Cathole
A 6–8 inch hole dug at least 200 feet from water for human waste in the backcountry. Pack out toilet paper. Part of Leave No Trace.
Clove hitch
A fast hitch used to tie a rope to a pole, post, or tree. Great for hanging lanterns or stringing a clothesline; not for heavy loads. Learn the knot.
Condensation
Moisture that forms inside your tent overnight from your breath. Crack a vent or door even in the cold to keep your sleeping bag dry.

D

Daypack
A small backpack (15–25 liters) for carrying water, snacks, and a layer on a day hike from camp. Not a full backpacking pack.
Dead reckoning
Navigating by tracking your direction, speed, and time elapsed instead of using landmarks. Useful when fog or trees obscure the view.
Declination
The angle between true north and magnetic north at your location. Adjust your compass for it before plotting bearings on a map.
Dehydrated meal
A pre-cooked meal with the moisture removed; you add boiling water in the bag. Light, fast, and clean — ideal for backpacking and easy car camping.
Dew point
The temperature at which air gets so saturated that water condenses out of it. When the overnight low approaches the dew point, expect heavy condensation.
Dispersed camping
Free camping outside developed campgrounds, typically on BLM or National Forest land. No facilities, no reservations, but real rules. Dispersed camping guide.
Dome tent
A tent with two crossing poles that arch over the top, forming a dome. The most common beginner tent — easy to pitch, sheds wind well.
Douse
To fully extinguish a campfire with water — soak, stir, soak again until the ashes are cold to the touch. The only acceptable way to leave a fire. How to extinguish a fire.
Dry bag
A waterproof roll-top bag for keeping clothes, electronics, or food dry in canoes, rain, or stream crossings.
Dutch oven
A heavy cast-iron pot with a tight lid, used over coals to bake, braise, or roast at camp. Comes in a flat-bottom kitchen version and a footed camp version. Cast-iron cooking.

E

Elevation gain
The total vertical climb on a hike, measured in feet (or meters), summed across every uphill section. A flat-distance number alone undersells effort.
Ember
A glowing chunk of charcoal left from a fire. Embers stay hot for hours and are how dutch ovens cook — and how forest fires start.

F

FCFS
First-come, first-served. A campsite that can't be reserved — you show up and claim what's open. Arrive early on summer Fridays or expect to be turned away. Reservation strategy.
Fire ban
A regional restriction on open flames during high fire danger. Stage 1 typically bans campfires; Stage 2 also bans stoves with flames; Stage 3 closes the area entirely. Always check the day-of status. Fire safety rules.
Fire ring
The metal or stone circle at a developed campsite where fires are allowed. Build inside the ring; never anywhere else, even if it looks fine.
Foil pack
A meal of meat, vegetables, and seasoning wrapped in heavy-duty foil and cooked over coals. Great kid food — almost no cleanup. Foil pack meals.
Footprint
A custom-shaped ground sheet sized to your tent floor. Protects the tent from abrasion and adds a moisture barrier on damp ground.

G

Ground cloth
A generic tarp or sheet under your tent — same role as a footprint, but cut from any material. Tuck it inside the tent's perimeter or rain runs under you.
Guy line
A cord that runs from a tent or tarp to a stake to add tension and stability in wind. Adjust with a taut-line hitch. Taut-line hitch.

H

Headlamp lumens
The brightness rating of a headlamp. 100 lumens is enough for camp tasks; 300+ for trail walking. Higher isn't always better — it kills your night vision.
Heat exhaustion
Early heat illness: heavy sweating, headache, nausea, weakness. Move to shade, drink water, cool the skin. Untreated, it progresses to heat stroke.
Hydration bladder
A flexible water reservoir (1.5–3 L) that lives inside your daypack with a hose to your shoulder strap. Easier to drink while moving than reaching for a bottle.
Hypothermia
When your core body temperature drops below 95°F. Watch for shivering, slurred speech, and fumbling. Get the person dry, insulated, and into warm shelter immediately.

J

Jetboil
A brand of integrated canister stove popular for backpacking. Boils water in 90 seconds. Brand name has become shorthand for the whole product category.

K

Kindling
Small dry sticks (pencil-thick to thumb-thick) that catch flame from tinder and build heat for larger logs. Gather a pile bigger than you think you need. How to start a fire.

L

Leave No Trace
A widely-adopted seven-principle outdoor ethic: plan ahead, camp on durable surfaces, dispose of waste properly, leave what you find, minimize fire impact, respect wildlife, and be considerate of others.
Lightning safety
If you can hear thunder, you're in strike range. Get off ridges and out from under tall lone trees. Crouch in a low spot until 30 minutes after the last thunder.

M

Mummy bag
A sleeping bag tapered toward the feet to reduce dead air space and warm faster. Less roomy than a rectangular bag, but warmer for the same insulation.

N

National Forest
Land managed by the U.S. Forest Service (USFS). Most allows dispersed camping for free; developed campgrounds inside forests have fees and reservations.
NPS / National Park
Land managed by the National Park Service. Stricter rules than National Forest — campfires only in fire rings, no dispersed camping, food storage strictly enforced.

O

Orienteering
The skill of navigating with map and compass alone. Foundational backcountry knowledge even if you usually rely on GPS — batteries die. Compass basics.

P

Paracord
A lightweight nylon kernmantle rope (550 lb test) originally used for parachute suspension lines. The general-purpose camp rope — every kit should have 25–50 feet.
Primitive site
A campsite with no hookups and minimal amenities — usually just a fire ring and a flat tent pad. Sometimes no toilet. Cheaper, quieter, more work.

Q

Quilt
An open-back sleeping bag that wraps over you instead of zipping around. Lighter than a bag because there's no insulation under you (your pad does that job).

R

Rainfly
The waterproof outer layer of a tent that goes over the mesh body. Pitch it taut — sagging fabric leaks where it touches the inner wall.
Recreation.gov
The federal reservation system for campgrounds, permits, and tours across NPS, USFS, BLM, and other agencies. Popular sites release on a 6-month rolling window at 10 a.m. ET. Reservation strategy.
Ridgeline
A horizontal line strung between two anchors to support a tarp shelter or hang gear. A taut-line hitch on each end keeps it tight. Taut-line hitch.
R-value
The insulation rating of a sleeping pad. R-2 is fine for summer; R-4 for shoulder seasons; R-5+ for cold ground or snow. The pad matters as much as the bag.

S

Sleeping bag temp rating
The lowest temperature at which the bag is rated to keep an average sleeper safe (not necessarily comfortable). Add 10°F of headroom for kids and cold sleepers.
Sleeping pad
The cushion between you and the ground — air, foam, or self-inflating. Without one, the cold ground will steal your warmth no matter how good your sleeping bag is.
Square knot
A flat, symmetrical knot that joins two ropes of equal thickness. Easy to tie ("right over left, left over right"), easy to untie. Not for heavy loads. Learn the knot.
State park
Land managed by the state, not the federal government. Reservation systems, fee structures, and rules vary by state — check the state's parks website, not Recreation.gov.

T

Tarp
A flat sheet of waterproof fabric strung up as a sun shade, rain cover over a picnic table, or minimalist shelter. The single most useful piece of camp gear after a tent.
Taut-line hitch
An adjustable knot that grips when loaded and slides when relaxed. The right knot for tent guy lines and tarp ridgelines. Learn the knot.
Teepee fire
A fire structure built with kindling leaning into a central peak over tinder. Lights fast, burns hot, collapses early — best for getting things started. Fire structures.
Tinder
Highly flammable, fluffy material that catches a spark — dry grass, birch bark, dryer lint, fatwood shavings. Distinct from kindling, which is one step bigger. How to start a fire.
Two-burner stove
A propane-fueled car-camping stove with two side-by-side burners. The standard family-camping cook setup — coffee on one side, breakfast on the other. Two-burner stove basics.

V

Vestibule
The covered area outside the inner tent door, under the rainfly. Park muddy boots and wet packs here so they don't come into the sleeping space.

W

Widowmaker
A dead branch or top hung up in a tree, ready to fall in wind. Look up before pitching your tent — never camp under one.
