Guadalupe Mountains National Park is an American national park in the Guadalupe Mountains, east of El Paso, Texas. The mountain range includes Guadalupe Peak, the highest point in Texas at 8,751 feet (2,667 m), and El Capitan used as a landmark by travelers on the route later followed by the Butterfield Overland Mail stagecoach line. The ruins of a stagecoach station stand near the Pine Springs visitor center. The restored Frijole Ranch contains a small museum of local history and is the trailhead for Smith Spring. The park covers 86,367 acres in the same mountain range as Carlsbad Caverns National Park, about 25 miles (40 km) to the north in New Mexico. The Guadalupe Peak Trail winds through pinyon pine and Douglas-fir forests as it ascends over 3,000 feet (910 m) to the summit of Guadalupe Peak, with views of El Capitan and the Chihuahuan Desert.
