Brantley Lake State Park sits on a 4,200-acre reservoir formed by the Brantley Dam on the Pecos River in southeastern New Mexico’s Chihuahuan Desert. Just 12 miles north of Carlsbad, the park serves as both a standalone recreation destination and an ideal base camp for visiting Carlsbad Caverns National Park (30 minutes south) and the Living Desert Zoo.
