Sleeping in a redwood forest was really lovely! The trees here are just breathtaking. This spot is not quite level but workable. 2-3' steep step up to get in so I'd suggest a high clearance vehicle. I was fine in an FJ. Bathroom area is clean. There are signs that water is only run at certain times but I didn't run into any issues. Spot 9 is fairly private and shaded with a picnic table, one bench, and two chairs.
Campground has a number of long-term/permanent residents at sites on the road down to the loop of rentable campsites which are all labeled although they are NOT in sequential order so finding your site can be tricky! 9 is right across from 3.
