A favorite spot of schoolchildren and their parents, The Witte Museum is newly graced by a huge, four-level permanent space called the H-E-B Body Adventure Powered by the University Health System, a center of interactive exhibits focused on exercise and other aspects of health. The $5 million center will allow visitors to test their strength, cycle through a virtual San Antonio River landscape, and learn to cook healthful Mexican food. The museum's backyard is also a big draw. It's a place where kids can see how early Texans lived in log cabins and other historic-style structures recreated on the grounds. The rest of this busy, mid-sized museum has a lot more to offer, too, including exhibits for both kids and adults that focus on South Texas history, culture, and natural science. Of course all the usual players are here—dinosaur skeletons, cave drawings, wildlife dioramas, and even some live animals and insects. The Witte is also the new home of an interesting collection of circus memorabilia, recently acquired from what was formerly the Hertzberg Circus Museum, a downtown building that has been re-purposed to house the Briscoe Museum of Western Art. My kids' favorite things to do at the Witte? They love to visit the hummingbird and butterfly garden out back, resting on the banks of the San Antonio River at Brackenridge Park. Free parking is available in the lot near the front entrance and in the Brackenridge Park Parking Garage on Avenue B. Self-guided visits and student educational programs are all part of the everyday fun. Plan on spending at least two hrs. if you bring the kids.
