Balcones Canyonlands National Wildlife Refuge is home to many native Texas wildlife and plants and was specifically established to protect the nesting grounds of the black-capped vireo and the endangered golden-cheeked warbler. This refuge also helps to protect water quality in central Texas and lies just north of Lake Travis, the drinking water reservoir for the Austin metro area. You can experience this rugged landscape by visiting one of our observation decks or hiking one of our 10 miles of foot trails.
