Where are Bear Canisters Required?
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. Bear canisters are the best way to protect Sierra black bears in the backcountry (when camping away from bear lockers) - this map shows where canisters are legally required. Use the external links in the sidebar to find bear locker locations in various parts of the Sierra.
