Build-a-Bear Workshop - The Oaks Mall

Build-a-Bear Workshop, located on the 2nd floor of The Oaks mall in Thousand Oaks, offers your little ones the ability to customize their own stuffed critters in a very experiential setting.

We've been to several birthday parties at Build-a-Bear (including our own son's 5th birthday party) and the process they take the kids through is enjoyed by all.

Birthday party way back when.

Kids get to choose the bear or other furry creature, add a "sound" or "voice," stuff it, choose a heart, stitch, fluff, name it, receive a birth certificate, dress it and transport the newborn home in a cute cardboard condo. And of course accessorizing the new family member requires follow-up visits. 

This Build-a-Bear Workshop was completely remodeled in 2013.

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.

The 1,200 foot long lazy river at Casitas Water Adventure is my kids' favorite.

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.

Weekend morning sessions 10:30 am to 2 pm and afternoon sessions 3 to 6:30 pm. Weekday hours are 11am to 6pm. The cost for the 2026 season is $23 per person on weekdays and $28 on weekends. Online reservations also include a $15 reservation fee.
