This lake and the one up the road, San Antonio Lake , are very popular motor boating locations in north San Luis Obispo County. Camping in the summer months are very hot and crowded and not cheap. On the positive side, the lake is huge with narrow passages where you can get off the main lake and fish or just have fun. Jet skis, kayaks etc are permitted. There is a beach for kids near the marina area campground. The campground is part of the private Lake Nacimiento Resort located near the marina and extends along the shore toward the dam with various types of sites. Some sites have direct access to your temporarily moored boat. It gets a bit noisy in the evening as college students party after a long fun day on the lake. All services are available even a store. Three stars for noise and crowds and prices ( tents 35$ hookups 50$, plus pet fee, vehicle fee,etc.)
