National Park Week: Guadalupe Mountains National Park © Clint Farlinger/Alamy
Cactus flowers and historic landmarks await visitors at this national park east of El Paso, Texas. Here you’ll find the four largest peaks in Texas, as well as towering El Capitan, a dramatic looking peak that was used as a landmark by stagecoach drivers delivering passengers and mail. Visitors here can view the ruins of the stage line and visit Frijole Ranch–once a center of ranching in this mountain range. Ancient rock art and pottery indicate people lived here as early as 10,000 years ago.
