Welcome to the San Marcos Discovery Center, a resource for the city's trails, parks, and river. We offer information on native flora and fauna found here in San Marcos, as well as conservation efforts that are in effect to enhance the San Marcos River and surrounding habitat. Stroll through Crook Park and enjoy our themed gardens, check out our workshop series offered each spring and fall, and don't miss our native plant sales to find native blooming trees, shrubs, vines, and perennials that can handle the Texas heat. Check out our programs and special events linked on the left. Admission is free.
