Casitas Water Adventure is a water park at the Lake Casitas Recreation Area that is open throughout the summer, generally from Memorial Day weekend through Labor Day weekend.
There are two distinct areas. For younger children, there is a multi-level jungle gym with waterfalls, bridges and slides in a lagoon with water up to 18" deep.
The 1,200 foot long Lazy River offers a cool water ride on inner tubes along a scenic waterway featuring waterfalls, fog filled bridges and jet sprays. The inner tubes are available on a first-come, first-served basis, but usually there are plenty of them on hand.
For the very youngest tots, a zero-depth pool sprays water from all angles, providing a safe, fun play area.
Shaded decks, lounge chairs, showers, restrooms and a snack bar are available, but food is not allowed inside the park (though you can bring bottled water). Certified lifeguards are on hand at all times and life jackets are available at no extra charge while supplies last. Locker rentals are available for a nominal fee.
Do take note that they don't heat the water here. It is a bit on the cold side for many, though on hot days this can be a good thing.
Lake Casitas Recreation Area is located at 11311 Santa Ana Road, Ventura. Take Highway 33 from Ventura towards Ojai, make a left turn on Santa Ana Blvd, then a right on Santa Ana Road 3 or 4 miles to the park entrance.

My kids particularly enjoy the Lazy River. There are some shady areas but do bring plenty of sunscreen as the sun beats down pretty hard out there. The water playground is definitely geared towards younger kids, with a large assortment of slides, water spouts and fun. My boys seemed to quickly get bored in the water playground starting around age 7-8, but they continue to enjoy the lagoon, which propels you round and round in a gentle current.
