Four Days. Three Nights. Beyond Big Bend.
Journey beyond Boquillas into the remote wilderness of Maderas del Carmen.


Begin in Marathon and journey through Big Bend National Park to Boquillas, MX. Cross the Rio Grande into Mexico, then travel deep into the Sierra del Carmen as the desert gives way to the mountain forests of Maderas del Carmen.

Explore a protected wilderness known for black bears, mountain lions, deer and remarkable birdlife. With limited visitation, Maderas offers a wildlife experience few travelers ever encounter.

Spend three nights surrounded by wilderness at Campo Dos or Campo Uno, with comfortable accommodations, traditional meals and evenings far removed from everyday life.

Spend your days exploring on foot or by vehicle with experienced local guides. Discover wildlife, mountain overlooks, caves, and the ecology of Maderas—all personally hosted by Marathon Mountain Adventures.
