This park is one of the best places in the United States to observe subtropical birds and wildlife that are more commonly found south in Mexico. The park is also one of the last natural refuges in Texas for cats such as the ocelot and jaguarundi. Popular fish include bass and catfish. The gate is open from 7 a.m. to 10 p.m daily. The warm climate and rare freezes make the park extremely attractive to visitors in the winter and early spring.
Current conditions including fire bans and water levels can vary from day to day.
