Distance: 912 miles one-way.
Guadalupe Mountains park in far West Texas is a hiker's paradise, with more than 80 miles of mild trails through canyons and springs and more strenuous back-country hikes where steep mountain switchbacks lead into the wilderness. The park also has sandy dunes and dry salt lakes.
