The Hidden Valley Campground has 44 sites. There are pit toilets, picnic tables, and fire pits. There is no water so bring plenty of your own. To secure a campsite, 1. Locate an empty campsite. 2. Occupy the site (set up a tent or leave personal items to show site occupancy). 3. Proceed immediately to an entrance station to complete registration and pay. You must pay for the site within one hour of set up. If arriving after entrance stations close, payment may be delayed until the following morning.
