- National Park
The Rio Grande flows from its headwaters in the San Juan Mountains of southern Colorado for 1,865 miles to the Gulf of Mexico near Brownsville, Texas. For 1,250 miles, the Rio Grande is the boundary between the United States and Mexico. In a remote stretch in west Texas, the river makes a curve to the northeast to form the "big bend." It is here that the wild character of the river lives on.
