The peak can be climbed at any time of the year by a maintained stony trail ( each way) with a elevation gain. The trail is part of the network of
hiking trails in the surrounding national park. A stainless steel pyramid marks the summit. It was erected by
American Airlines in 1958 to commemorate the 100th anniversary of the
Butterfield Overland Mail, a
stagecoach route that passed south of the mountain. One side of the pyramid has the American Airlines logo. The second side displays a
U.S. Postal Service tribute to the
Pony Express Riders of the Butterfield Stage. The third side displays a compass with the logo of the
Boy Scouts of America. A hiker was found dead on New Year's Eve 2022, as there were wind gusts of more than per hour and wind chills were "well below freezing". "At nearly above sea level, Guadalupe Peak is a mountain environment with associated risks not found elsewhere in Texas," the park said, noting that the hike is a "very strenuous, round trip hike with a elevation gain" to the highest point in the state. ==Climate==
