Bear Canisters & Food Storage: The Complete Backcountry Guide
By Peak Pine Gear Editorial Team · Published 2026-09-30
A fed bear is a dead bear — and proper food storage is how hikers keep bears wild and camps safe. Here's the complete system: what's required where, and how to actually do it.
The three approved methods
1. Hard-sided canister. The gold standard — and legally required in many of the best places to hike: much of the Sierra Nevada (including most of the JMT corridor), Olympic's backcountry, parts of the Adirondacks and Rockies. The BearVault BV500 (~$80) is the thru-hiker standard: transparent, 11.5 L, fits ~6 days of food for one. 2. Ursack. A bulletproof Spectra-fabric bag that bears can't open or tear. Lighter than a canister and approved in many (not all) canister-required areas — check the specific regulation, because 'bear-resistant container' definitions vary by agency. 3. The hang. Where containers aren't required, a proper hang works: 12 feet up, 4 feet from the trunk, 4 feet below the branch. Realistically, most hangs fail — which is why agencies keep moving toward containers.
Packing a canister efficiently
Food, trash, and all scented items (toothpaste, sunscreen, lip balm) go in — nothing else. Strip excess packaging before the trip, freeze-dried meals pack flat, and day-one lunch can ride outside the can. A BV500 holds roughly 6 person-days; plan 1.5–2 lbs of food per person per day.
Camp kitchen rules that matter more than the container
- Cook and eat 100+ feet from where you sleep, especially in grizzly country.
- Never — not once — bring food into the tent. Bears have long memories for sloppy camps.
- Store the canister on flat ground, away from cliffs and water it could roll into. Bears will play soccer with it; let them lose interest, not find a launch ramp.
Frequently asked questions
Do I need a bear canister for black bears?
Where regulations require it, yes regardless of species. Elsewhere it's still the most reliable method — habituated black bears in popular areas defeat amateur hangs routinely.
What about grizzly country?
All the same rules apply, plus: carry bear spray within reach (not in your pack), hike in groups, and make noise in low-visibility terrain. In most national parks in grizzly range, canisters or food-storage lockers are mandatory.
How do I check what's required where I'm going?
The land agency's website (NPS, USFS, state parks) for your specific zone — rules vary by trailhead, and rangers do check. When in doubt, bring the canister; it's never the wrong answer.
