Vast and remote, Big Bend's unspoiled ecosystems and phenomenal topography call out to adventurers. Walk into the stark wilds of the Chihuahuan Desert, wind your way through narrow limestone ravines and box canyons, hike between towering cliffs along the mighty Rio Grande, then cross the river in a rowboat. Climb into the rich alpine forests and rugged ridges of the Chisos Mountains, a "sky island" rising from a sea of sand, and spend evenings under inky skies spangled with stars. Your expert MT Sobek guides will identify enchanting flora and fauna, geologic marvels, and ancient petroglyphs. Together you will explore the fascinating culture and history of the Texas Mountain Trail.
