The Chisos Mountains are the heart of Big Bend National Park. They extend twenty miles from Punta de la Sierra in the southwest to Panther Junction in the northeast. It is the only mountain range totally contained within a single national park.
Boquillas Canyon is the longest and deepest canyon in Big Bend National Park. The vertical relief from nearby Pico del Carmen, to river level is over 7,000 feet, somewhat deeper than the Grand Canyon of the Colorado.
The Big Bend National Park area is accessible by two small towns; Marathon and Lajitas. Located about 100 miles from the entrance of the park, Marathon is a small town with a selection of dining options, as well as the beautiful Gage Hotel. Should you wish to stay closer to the park, the Lajitas Resort in Lajitas, is located right at the entrance to the park and offers activities such as horse riding and ATV riding within the park.
