Traffic accidents cause more injuries to visitors than natural hazards.
Use pullouts to watch wildlife and allow faster traffic to pass. Be alert for pedestrians and bicyclists. Driving off roads is not permitted. Defacing park features, collecting natural or archeological objects, picking wildflowers, and littering are illegal. Lock your vehicle, store your valuables securely and report thefts or accidents promptly to a ranger.
