San Bernard is a very diverse national wildlife refuge, stretching inland from the Gulf coast across saline and freshwater marshes and up the Brazos and San Bernard river watersheds, protecting varied habitats ranging from coastal marshes and freshwater wetlands, to upland prairies and bottomland hardwood forests. Whether gazing out across saline marshes, or under a dense canopy of oak, pecan, and green ash trees, the refuge is reminiscent of what the American settlers to Texas experienced 200 years ago. With three recreation areas and 10 trails, San Bernard has a lot to explore.
