The Lower Rio Grande Valley National Wildlife Refuge was established in 1979
with a management priority to protect biodiversity. As a wildlife corridor,
the refuge follows the Rio Grande along the last 275 river miles. It connects
isolated tracts of land managed by private landowners, non-profit
organizations, the State of Texas, and two other National Wildlife Refuges:
Laguna Atascosa and Santa Ana.

Established in 1943 for the protection of migratory birds, Santa Ana National
Wildlife Refuge is positioned along an east-west and north-south juncture of
two major migratory routes for many species of birds. It is also at the
northern-most point for many species whose range extends south into Central
and South America. The refuge is right in the middle of all this biological
diversity, which is what makes this 2,088-acre parcel the ‘jewel of the
National Wildlife Refuge System.’ Though small in size, Santa Ana offers
visitors an opportunity to see birds, butterflies and many other species not
found anywhere else in the United States beyond deep South Texas.

Most out-of-town visitors will see or hear a new bird species before even
making it into the refuge’s Visitor Center! Sit in the refuge’s breezeway and
watch the birds or hike more than 14 miles of trails. Take an open-air tram
ride, go for either a 3 or 7-mile bike ride, or join a guided nature walk.
