Near Devil’s Den

from the Big Bend National Park Desert Hikes brochure:
Devil’s Den is a dramatic limestone slot canyon in the park’s northern backcountry. Follow the trail towards Dog Canyon. After 1.5 miles take a side trail off to the right into a wash. In another 0.5 mile, take the large wash that intersects from the left which leads directly into Devil’s Den. You may hike into the den, or hike up along the southern edge of the deep crevice for great views into the canyon. You can then enter the den and hike back through it. Small tinajas hold water during the rainy season.
