Stay cool, hydrated, and informed to beat the heat while visiting the park! If you plan to visit the park on a hot day or be out in the sun all day, follow these safety tips:
Check the weather forecast and park alerts. Check the weather conditions for extreme heat alerts and stop by the visitor center before visiting the park.
Take time to acclimate to high altitudes. Your body loses more fluids at high altitudes, increasing your risk of dehydration and heat-related illness. Allow several days to acclimate before starting any strenuous exercise.
Pick the right activity for your abilities. Use the “Plan Your Visit” section to pick an activity.
Pace yourself. Start your hike slowly and pick up the pace gradually.
Take plenty of breaks. Rest in the shade or cool down in air conditioning.
Drink plenty of water. Stay hydrated and drink before you feel thirsty. Plan to bring extra water, just in case you need it. Sports beverages can help replace salt and minerals lost from sweat.
Wear sun protection. UVA/UVB sunscreen, a hat, lightweight and light-colored clothing, and sunglasses are recommended.
Do not leave children or pets in a parked vehicle. The temperature in a car can rise very quickly!
