Lost Creek Campground has 16 sites for tents (no RVs). All sites are first-come, first-served. For more information about these campgrounds, follow the links above.
Overnight parking elsewhere in the park is prohibited, except for guests at the park's motels and for backpackers who obtain a backcountry permit.
