Santa Elena Canyon in Big Bend National Park is a favorite hike and river trip for visitors to Far West Texas. Here's what the park's website says about the hike:
"1.7 miles roundtripThis trail begins at the end of the Ross Maxwell Scenic Drive. Although a short trail, it is one of the grandest spectacles in the park. After crossing Terlingua Creek, the trail climbs several short switchbacks and then gradually descends along the banks of the Rio Grande. Hikers are surrounded by lush riparian vegetation and 1,500-foot towering vertical cliffs of solid limestone. The trail ends where canyon walls meet the river. Take a lunch and enjoy the scene.
Note: Following rains, flash floods, or periods of high water, Terlingua creek can be impassable, effectively closing the trail."
