Many Texas Wildlife Management Areas are open for activities such as biking, primitive camping, birding, fishing, hiking, equestrian activities, driving tours, and wildlife viewing.

Many times you need minimally a Texas Limited Public Use Permit (LPU - #175). You can purchase a Limited Public Use Permit or Annual Public Hunting Permit at any location that sells hunting licenses or at the Texas License Connection. If purchased online a representation of receipt is acceptable until official printer version has been mailed to you. In some cases it's not obvious when you need a permit for a Texas Wildlife Management Area so it might be better to be safe, because Texas game wardens do check for such permits.

In the late 70's the Guadalupe delta area was identified by the US Fish and Wildlife Service and Texas Parks and Wildlife as a wetlands area that needed to be preserved to protect the wildlife habitat. Guadalupe Delta Wildlife Management Area consists of four units, Mission Lake Unit (4,447.62 acres), Hynes Bay Unit (1007.72 acres), Guadalupe River Unit (1138 acres) and the San Antonio Unit (818 acres). The Guadalupe Delta WMA units are located in Calhoun, Victoria and Refugio Counties within the delta of the Guadalupe River along the Texas coast between Houston and Corpus Christi. The units of the Guadalupe Delta are freshwater marshes subject to flooding from the Guadalupe River and its adjacent bayous. Riparian areas along the numerous small bayous form "corridor forests" of pecan, black willow, cedar, American elm, hackberry and green ash, and provide excellent forage area for neotropical songbirds.
