Basalt campground is part of the San Luis Reservoir State Recreation Area http://www.parks.ca.gov/?page_id=558 however it is not located on the reservoir. It is about a mile away, up the hills above the reservoir. It can be hot, dusty, and windy, especially in the afternoons. There are plenty of boat ramps and parking areas nearby along the lake for people to use to boat, swim, fish, etc. We stayed in May and it was very dry, hot, and a windy at night. The bathrooms were not very clean and there were no showers, but the website says they have upgraded the facilities recently, and added showers, so they should be a lot better. Santa Nella is close by to stock up on supplies. Each campsite has a picnic table and a firepit/grill combo. The grill at our site had seen better days. The campsites themselves are very large, but there isn't many trees or bushes to offer privacy from your neighbors. You can reserve online, but it doesn't let you pick a specific campsite. Once you get there, the ranger assigns you a spot, which is a little disappointing. I would prefer to choose my spot if I am reserving online.
