I stayed here in late July for three nights with my 6 year old daughter and our 3 friends.  Site 13 was easily large enough for four tent set-ups in separate areas of the site, though none of them were completely level.  There are three kinds of sites in the campground - those backed against the woods or the fence separating the campground from the ranger houses, those in the middle, and those next to the Ave of the Giants.  The ones with the most room and privacy were backed up against the woods/fence, and we were in one of those sites. Each sites has a metal fire barrel (with half grate), a picnic table, and enough room to park two vehicles. Each site also has redwoods growing in them and often large stumps (many with steps cuts into them for climbing).  Water spigots are available about every other site. 

This was a very family friendly campground. My daughter and her friend loved playing among the trees and stumps, and riding her scooter around the loop.  Rangers frequently walked/drove around the campground and a camp host went around every morning to check sites and car tags.  Of the three nights we were here, only one was kinda loud with music and voices, but they went subdued around 11 pm. The only other bother were the three dogs in the adjacent camp that were....  well, dogs (they barked a lot). Road noise was present but not distracting. 

The location was great. You could stroll over to the visitor center (rangers set up on the outside over the weekend) or across the street to the nature trails.  A short drive takes you into Myers Flat or Founders Grove, and you are smack in the middle of the Ave of the Giants. I would have given this campground 5 stars, if it wasn't for the comfort stations (bathrooms).  They had a sewage backup/clog the day we arrived, so we didn;t have showers for the time of our stay. They brought in port-a-potties within hours of the restrooms being closed, but not sinks or soap.  With CV-19, I was not happy about not having a clean restroom facility.  

Despite this, however, I was glad I went.  The area was beautiful and peaceful. We went strolling around the redwoods and swimming in the Eel River (south fork). Would recommend.
