Beautiful location. The Saturday I visited a number of youthful and knowledgeable volunteers were doing an excellent showing the animals to visitors and letting children see the animals up close. There are exhibits on mammals, reptiles, amphibian, fish, buttterflies,shells insects, etc. both native to Texas and from other parts of the world. Very fascinating. I thought the animals all seemed healthy and well cared for and cages were very clean. Larger mammals and a one mile interpretive trail (not wheelchair or stroller accessible as it is narrow) are outside. A brochure telling about the 20 interpretative sites on the trail is available at the front desk. Closed Sunday and Mondays.
