National Park
Big Bend National Park occupies a large part of Brewster County
Big Bend National Park covers 801,163 acres entirely within Brewster County and protects the largest stretch of Chihuahuan Desert in the United States.
Big Bend National Park sits entirely within Brewster County along the Rio Grande. At 801,163 acres it is the eighth-largest national park in the lower 48 states. The park holds the Chisos Mountains — the southernmost mountain range in the continental United States, completely enclosed within the park — with peaks reaching nearly 8,000 feet. Elevations drop to under 1,800 feet at the river, creating sharp climate zones within a short drive.
Congress authorized the park in 1935, and it opened to the public in 1944. Today it records 450 species of birds, over 1,200 plant species, and 56 reptile species. The Rio Grande forms three major canyons — Santa Elena, Mariscal, and Boquillas — accessible by river or trail. The park is also a UNESCO Man and the Biosphere international reserve.
Peak visitation runs November through April. Summer temperatures on the desert floor regularly exceed 100°F by midmorning. Entrance fees apply; check the NPS fees page before you go because fees can change. Backcountry camping requires a permit obtained at the Panther Junction Visitor Center.
