Along the banks of the Laguna Madre, Laguna Atascosa National Wildlife Refuge is one of the largest remaining protected wild areas in the Lower Rio Grande Valley. Located 20 miles northeast of Brownsville, Texas, this refuge features tour roads, including Lakeside Drive and the 15-mile Bayside Drive loop, hiking trails, bicycle trails, and a visitor center open to the public year round.
Considered one of the most biologically diverse refuges in the nation, the Lower Rio Grande Valley National Wildlife Refuge spans over 100 tracts. This refuge provides habitat for thousands of plant and animal species, including birds and butterflies found nowhere else in the United States.
With over 400 bird species documented on just 2,088 acres of prime habitat, Santa Ana National Wildlife Refuge is the “jewel” of the National Wildlife Refuge System. Located where the subtropical climate, gulf coast, great plains, and Chihuahuan desert meet, millions of birds and over half of all U.S. butterfly species funnel through this area on their way to and from Central and South America.
