North of Simi Valley, a few miles from Magic Mountain Amusement Park, Lake Piru used to be a great get away for folks in LA. But a severe drought the past few years has lowered the levels of the lake drastically. There is no longer a fresh water swimming hole, and the boat launch seems to be longer than the drive into the park. Still it is a nice park with mainly just electric hookups. You can get FHU for quite a bit more money. There are several dump stations and fresh water stations.
