Guadalupe Mountains National Park! Here's what the park's website says about this trail:
"Hike the streambed of Pine Springs Canyon, then climb the natural rock of the Hiker's Staircase, to the finale - the Devil's Hall. This rocky trail has very little elevation gain, and leads you through maples, ponderosa pine, and many plant varieties of the Chihuahuan desert. The trail is rated moderate; though it is only 4.2 miles round trip, allow 3-5 hours to enjoy this hike."
