Van Damme State Campground- $45 nightly fee.
Worth every penny. Campground is pristine, the bathrooms are probably the nicest I've ever used while camping. Showers are $1= 5 minutes and are steaming hot. A box of firewood is $10 but you get a decent amount, if you don't like the price there's Fort Bragg maybe 18 min away.
Most spots have many trees, but take note campsites 66-69 are in a clearing with none. The campsites near the entrance of the park are very small and mushed together.
Check-in 2pm checkout 12pm. 3 car max per the website.
