Save the Day Passes
Visitors are asked to stop by the headquarters office to purchase their day passes and camping permits. Visitors will be provided directions how to access camping areas and the boat ramp area through the Highway 59 gates (Henry Cuellar Road).
Also, the same areas are experiencing low water pressure due to a ruptured city water line that is being repaired in the city. Restrooms and showers within the park will be closed at boat ramp, 100 camping loop , pier and bathhouse until water pressure is restored by the city. All other restrooms in the park are operational. We will update as more information is provided.

Many parks fill to capacity on weekends and holidays. Pre-purchase a day pass and guarantee your entry and parking. Day passes are:
  • Valid until 10 p.m., unless the park closes earlier.
  • Available up to 1 month in advance.
  • Not transferrable to another person or park.
  • Also sold at the park, if available.
