For Your Safety
There are no reliable water sources in the backcountry. To insure you have enough water for drinking and cooking, please carry one gallon per person per day (water weighs approximately 8 lbs. per gallon). Water faucets are located at every visitor center. Carry additional water for your vehicle.
Too much sun can be dangerous; take heat safety seriously. more...
Be Alert for Poisonous Snakes and Insects
Watch where you place your hands and feet, carry a flashlight at night, and shake out your shoes and clothes before putting them on. Remember, snakes and insects are protected in the park. Please do not harm or harass them.
Mountain lions and black bears are a natural part of the environment; be prepared for the possibility of an encounter. Keep small children close at all times. Don't let them run ahead on trails. If you feel threatened by a lion or bear, do not run. Instead, look large and yell, scream, wave your arms, and throw rocks or sticks if necessary. Pick up small children. Report lion and bear sightings in detail to a ranger.
Secure Your Food
Do not feed any wildlife. Keep your food in a hard-sided vehicle or food storage locker. Ice chests are not animal-proof. more...
