Lake Casitas Campground has more than 400 RV, trailer and tent campsites along the lake’s north shore. The 2,500-acre lake is only 10 miles inland from Ventura and offers a wonderful spot for families to relax by the water. Fishing for largemouth bass is popular here. Although there is no body contract allowed with the lake’s water, Lake Casitas’ Water Adventure Park with water slides, inner tube rides, and a swim lagoon, has something for everyone. Many of the RV sites have electric and water hook ups available.
