You should always be aware of your surroundings when hiking remotely. Bring bear spray and follow the National Park Service’s wildlife safety guidelines.
Note also that such destinations are very vulnerable to wildfire in the summertime. Always follow fire restrictions to the letter, never light campfires when there are burn bans in effect, and don’t smoke cigarettes or light fireworks in the wilderness.
In addition to harming natural areas and endangering human settlements, you can lose your life.
