The Bahia Grande is a wetlands area that lies on both sides of Hwy 48 between Port Isabel and Brownsville, Texas. Once home to many species of marine life, the 11,000-acre area dried up as a result of the dredging of the Brownsville Ship Channel in the 1930s. When tidal waters could no longer flow into the area, the abundant fish and wildlife disappeared. In their place, the combination of wind and sand flats created health problems for surrounding communities.
Abundant birds of prey, songbirds, shorebirds and waterfowl give visitors great viewing and photographing opportunities. You can sign up for the tour through the Laguna Atascosa Wildlife Refuge. It’s a tour that we highly recommend.
