Just a forest service road. The area close to the road is closed to camping entirely. I showed up at 1am and missed that part since I'm so used to seeing no campFIRES and was hassled by a local for making their scenic walk less pretty. But if you look at the map posted you just need to be further in from the road - you'll see new signs for 14-day limits. Lots of mountain bikers riding past since there are a ton of trails out here. They also seem to be grumpy about seeing a vehicle parked out here, but oh well. 

I don't know who is marking this area for services and water and toilets and RV hookups…. it's just a dirt road. However I do get 2-3 bars LTE on AT&T and Verizon even further in where you can camp.
