You are responsible for your safety.
Natural areas present hazards. Cold temperatures, icy or uneven ground, wild animals, biting insects, and changing weather all pose dangers. Rocks roll, trees topple, and limbs drop without warning. People create other hazards with campfires, traffic, snowplay, and poor decisions.
The National Park Service works to reduce risks, but your safety is in your own hands. Keep alert, read warnings, and ask a ranger for advice.
