Welcome to Guadalupe Mountains National Park
Despite its low profile, it's a Texas high spot, both literally and figuratively. At 8749ft, Guadalupe Peak is the highest point in the Lone Star State. The fall foliage in McKittrick Canyon is the best in west Texas, and more than half the park is a federally designated wilderness area.
The NPS has deliberately curbed development to keep the park wild. There are no restaurants or indoor accommodations and only a smattering of services and programs (so plan ahead to keep your gas tank full and your cooler stocked). There are also no paved roads within the park, so whatever you want to see, you're going to have to get there on foot. But the hiking and high-country splendor are top-notch.
