We traded off the stop at Burro Mesa Pouroff that arrived after Sotol Vista Overlook with Mule Ears View Point which came up next. The landscape at Big Bend National is fascinating. Beautiful panorama is enormous. Each mile we made was rewarded with different spectacular scenery. If I were have a chance to visit without the time constraint, I would love to visit and walk through every single trail in Big Bend National Park. Mule Ears Peaks View Point sits along Ross Maxwell Scenic Drive at 15.5th-mile from Castolon-Santa Elena Junction. Before turning into this viewpoint, the brown hills and spires greeted us on either side of the road. They are 'rhyolite' which was formed when igneous rock seeped to the surface through older layers of sediment. The unique formation of Mule Ears Peaks which resembles a pair of mule's ears (that's how the name came about) has long been an important landmark to travelers along Rio Grande River. These twin peaks are dikes, were once enclosed in tuff or volcanic ash. Over time, erosion took place and striped away all the softer surrounding rocks, eventually exposed the black igneous rock to appear like a twin pillars. Located about 8 miles north of Castolon, there is a hiking trail from this spot leading to a small spring that gave the trail its name: Mule Ears Spring Trail. A round trip would take 3.8 miles and it is graded as moderately steep but you may get to enjoy the spectacular geology and mountain-desert view.If you are looking to stay at this place you can try to do a Hotel Search
