Tips for Camping in Black Bear Country

Bears do visit our campgrounds. Here are a few simple reminders to help keep you and the bears safe and ensure that you have an enjoyable stay.

  • Never keep food in your tent.
  • Store food and garbage out of a bear's reach by storing food securely in the trunk of your vehicle.
  • Remove your trash from your site daily and place in the campground dumpsters.
  • Remember to secure your pet’s food also
  • If a bear comes into camp, don't feed it! Scare it away by making noise.
  • See a park employee to get more detailed information on how to camp in black bear country or visit: Living With Black Bears.
