Begin spraying when the charging bear is 30-60 feet (10-20 yards) away. Spray at the charging bear so that the bear must pass through a cloud of spray. Keep spraying until the bear changes direction. If the bear continues to charge, spray into its face. Leave the area promptly. Bear spray is sold at gift shops, outdoor stores, service stations, and bookstores inside the park, as well as in local communities. Always select an EPA-approved product that is specifically designed to stop bears. Personal defense, jogger defense, law enforcement or military defense sprays may not contain the correct ingredients, or have the proper delivery system, to stop a charging bear.
