There are no campgrounds in the park. Backpackers with backcountry permits can stay in the park after it closes for the evening, but they must hike at least 1 mile into the wilderness before setting up camp. For drive-in camping, head to Holbrook, 25 miles west of the park on I-40, where several commercial campgrounds offer all the usual amenities.
