Quick answer: in many parks (including parts of Yosemite, the Sierra Nevada and the Adirondacks), approved hard-sided bear canisters are required. Where they are not, a bear-resistant bag such as the Ursack Major or a proper bear hang is an option. Choose a canister by trip length and volume: a 7–8 day trip for one person usually needs around 10–12 litres. Always check the rules for your area first.

Canisters vs bags vs hanging
| Method | Pros | Cons |
|---|---|---|
| Hard canister | Approved almost everywhere, crush-proof, doubles as a seat | Heavy, bulky |
| Bear-resistant bag (Ursack) | Lighter, flexible | Not approved in some parks; food can get crushed |
| Bear hang | Light (just a sack and rope) | Hard to do well; many areas lack suitable trees |
What to look for
- Approval: look for IGBC or SIBBG approval and check the specific park list.
- Volume: roughly 1–1.5 L per person per day of food and scented items.
- Weight: 0.8–1.3 kg is typical.
- Opening: some lids need a coin or screwdriver; tool-free lids are easier with cold hands.
- Clear or opaque: transparent canisters make it easy to find food.
Bear safety basics
- Store all food, trash, toiletries and scented items in the canister.
- Place it at least 60 m (200 ft) from your tent, away from cliffs and water.
- Cook and eat away from your sleeping area.
- Carry bear spray where grizzly bears live and know how to use it.
