Amistad National Recreation Area

Along the Mexican border in south Texas, at the confluence of the Rio Grande, Devils and Pecos rivers, the Amistad Reservoir offers dive opportunities inside the Amistad National Recreation Area, so designated in 1990. Considered the most popular dive site is Diablo East Dive Cove, with a dive platform at 40 feet (12 m), two boat wrecks, and a maximum depth of 100 feet at the outer point of the cove. Castle Canyon has a few protected coves to beach a boat and dive; and the Highway 90 Bridge offers good visibility on its leeward side. A dive flag is required during all dives except in Scuba Cove. The nearest multichamber recompression facility is 150 miles (240 km) away in San Antonio. A single chamber may be available at Val Verde Medical Center in Del Rio. Besides aquatic life, divers can find sunken boats, railroad tracks and even buildings.
