The number of whooping cranes has gradually risen. A total of 132 whooping cranes spent the past winter at the refuge, arriving in October from nesting grounds in Canada. Most whoopers leave the area in April. Most have returned by November, but the refuge, located off Texas Highway 35, is open the year round. In addition to whoopers, the refuge is home to deer, javelinas, feral hogs, armadillos, raccoons, cougars, bobcats, and alligators.
Visitors can hike, take in a film, picnic, or just drive through the park.
The interpretive center features stuffed birds and animals that can be found at the refuge. The center's bookstore stocks literature on wildlife. A 16-mile trail loops through the refuge. Overnight facilities are available for organized youth and educational groups by prior arrangements. Camping for the general public is prohibited.
