We love Lake Hosmer, it is always beautiful in the summer.  The spaces are nice, although sometimes hard to get into you will need to book way in advance (they will release sites about 6 months early).  You can Kayak on the lake and there is also a boat ramp, store, and marina not too far down the road.

This facility has vault toilets and each site is equipped with a picnic table and fire pit with grill. This is a dry camping facility so bring it in and out.
