Sandwiched between Mexico and New Mexico, Big Bend Texas integrates Hispanic culture into the American mix. The Pecos and the Rio Grande rivers are just two of the natural attractions that abound in this part of the state, the latter forming a natural border between Texas and Mexico. In Big Bend National Park, one of the largest national parks in the United States, guests are able to hike, float on commercial float trips on the Rio Grande, camp and birdwatch. The largest center in the region is El Paso, a city that provides easy access to its sister city of Juarez, Mexico. While in El Paso visit Fort Bliss, the Ysleta, Socorro and San Elizario missions, and the El Paso Museum of Art. Other areas of interest in Big Bend Texas include the Amistad National Recreation Area, Guadalupe Mountains National Park and the city of Del Rio.
