Big Bend National Park
“Big Bend National Park is a geological marvel evidenced in sea fossils and dinosaur bones to volcanic dikes that mar the desert landscape. It’s a world of species diversity from the meandering river corridor that sidles across the desert floor to the sky island ridge tops that reach for the stars.” In addition to the accessible trails, there are about six day hikes described as “easy”. Check with the Park to be sure.
