All campsites are on the reservation system, recreation.gov. We recommend making reservations a few weeks in advance and as much as three months in advance during holidays and from January to April. Larger campsites often fill up early so tent campers may find last minute availability more frequently. The park does not offer any walk-in or first come first serve camping. If you arrive without a reservation you may be able to make a reservation using wi-fi at the visitor center. Dispersed camping without a reservation is available on Pinery Canyon Road (Forest Road 42) 6 miles outside the park.
