Always follow park rules, ranger directions, posted closures, and local laws. Never approach, feed, call, touch, or crowd wildlife. Stay inside your vehicle when required or whenever animals are near the road; never stop or stand in a travel lane, and pull completely off the roadway only where legal and safe. Keep the required distance and leave immediately if an animal changes its behavior because of you.
