Where are Bear Canisters Required?
While camping in the Sierra, proper bear-proof food storage is highly recommended, and in some places required by law. Sierra land managers are unified in their desire to protect black bears from the ill effects of obtaining human food, but specific regulations vary between different parks and forests.
At many campgrounds and trailheads in the Sierra there are large, stationary bear-proof food storage lockers available for your use. There are external links in the sidebar to help you find bear-proof locker locations.
Portable bear canisters are the best way to protect Sierra black bears in the wilderness when camping away from bear lockers. This map shows where canisters are legally required.
