If you're in Fort Davis with a few hours set aside for a great hike, consider the Modesta Canyon Trail at the Chihuahuan Desert Nature Center and Botanical Gardens. In the middle of the hike, there's a small spring-fed pool in a shady spot...a great place to rest!
It is a 1.75 mile loop but is rated moderately strenous due to its rocky, uneven footing. Plan to set aside 1.5 to 2 hours for the hike, plus more time to check out the other trails and the great gift shop at the visitor center.
