Bats, bees, and crystal caverns are among the subjects of the Discovery Lab at this museum in the 80-acre Nature Center, which features lots of interactive exhibits. Tortoises, lizards, and vultures in the Animal Exhibits—including orphaned or injured creatures brought here from the wild—also hold kids’ attention. An Eco-Detective trail highlights pond-life awareness. The Dino Pit, with its replicas of Texas fossils and dinosaur tracks, lures budding paleontologists. A variety of specialty camps, focusing on everything from caving to astronomy, are offered from late May through August.
