Located 110 miles east of El Paso, Guadalupe Mountains National Park has been described as one of America’s best kept secrets. Created on September 30, 1972, Guadalupe Mountains National Park preserves one of the best examples of Permian-era (260 to 270 million years ago) geology in the world. Formed from a reef in the ancient Delaware Sea, long since dry, the Guadalupe Mountains are one of the exposed sections of the 400 mile long, horseshoe-shaped Capitán Reef, the world’s largest exposed fossil reef. The park boasts 46,850 acres of designated-wilderness, the largest wilderness area in Texas, with another 35,484 acres of backcountry that are eligible for wilderness study, and more than 80 miles of trails, about 60% of which are designated for horseback riding. Trails range from easy to strenuous, and wind through desert, riparian, wooded and forested areas. Climb to the “Top of Texas,” 8,749 foot Guadalupe Peak, the highest point in Texas or explore the Salt Basin Dunes (the park’s lowest point at 3,689’), which contains the second largest gypsum dune field in the US, on the west side of the park, near Dell City. The park has 7 of the 10 highest peaks in Texas. Trails can be steep, rocky and rugged, so wear sturdy, closed-toe shoes or hiking boots.
