Guadalupe Peak — Highest Point in Texas
A day hike to Guadalupe Peak (8,749 feet) — the highest point in Texas and the highest summit in the Guadalupe Mountains National Park, 110 miles east of El Paso. The Guadalupe Peak Trail is a strenuous 8.4-mile round trip with 3,000 feet of elevation gain on a well-maintained NPS trail; the summit cairn holds a stainless steel pyramid placed by American Airlines in 1958 to commemorate the centennial of the Butterfield Overland Mail route that passed through Guadalupe Pass below. The view from the top spans four states on clear days: Texas, New Mexico, Chihuahua, and Sonora. The Guadalupe Mountains are a block-faulted limestone range — the largest exposed Permian reef in the world (the Capitan Reef, formed 265 million years ago when a tropical sea covered West Texas). The massive El Capitan cliff face (8,085ft) visible from the highway is the southeastern anchor of the reef; the Guadalupe Peak summit is the highest point on the reef mass.
