The park provides a chance to study unique plants, animals and birds of the region. Many species of birds unique to the southern U.S. are found here. Enjoy camping, hiking, picnicking, bird watching, nature study, boating and fishing. Professional park naturalists conduct daily, on-site birdwatching and wildlife tours from December through March. A visitor birding information center is also available from December through March.
All tours begin at the group pavilion.
Tours last about 6 to 8 hours. Reservations and advance payment for these tours may be made by mailing payment to the park address. Income from tours supports the conservation efforts of Bentsen-Rio Grande Valley State Park. There is a late arrival area which is used for winter-late arrivals and an overflow area the rest of the year. Visitors may rent bikes, the volleyball court, the shuffleboard court, and bird observation blinds.
