Big Bend National Park
Mountain Trail Region
The Big Bend region of Texas, named for a horseshoe curve where the Rio Grande carves canyons into the mountains along the border of the far southwestern portion of the state, is home to the first and largest national park in Texas. Encompassing over 1,250 square miles, including over 100 miles of the Rio Grande corridor, Big Bend National Park represents part of the northern reaches of the great Chihuahuan Desert, the second largest desert in the Western Hemisphere.
