While hiking on the dunes, be aware of your location as it is easy to become disoriented. Watch the weather, as sandstorms can reduce visibility and make it nearly impossible to find your way. Heat-related issues are also a concern; carry water with you, and drink at least a gallon of water per day on hot days. Sunscreen is a must.
When driving on the park roads follow speed limits, use turnouts, and lock your vehicle when not attended.
