Davis Mountains State Park....great for hiking too! The park's website describes the trail this way: "Skyline Drive Mountain Bike Trail , Use: mountain biking and hiking. This 3.25-mile loop trail was designed with mountain bikers in mind, but hikers are welcome as well. Starting in the park’s campground, the trail joins with the original route of Skyline Drive, hand-built by the Civilian Conservation Corps in 1933. Elevations range from 4932’ to 5300’ on this undulating trail, which offers prime views of the Limpia Canyon riparian corridor.
