Bajo Del Diablo

Bajo del Diablo (Devil's Pinnacle) is a volcanic pinnacle dive site within the Caño Island Biological Reserve off Costa Rica's Pacific coast, rising from depth with surrounding canyons between 15 and 40 metres (45–130 feet).

The terrain consists of volcanic pinnacles and rocky canyon formations, with a bottom of rock reaching a maximum depth of 40 metres (130 feet) and a shallowest point at 15 metres (45 feet). The site carries the strongest currents in the reserve, and the depth and nitrogen narcosis risk place it at advanced-to-intermediate-plus level, with strong current listed as the primary hazard alongside narcosis at greater depths.

The waters around the pinnacle and its canyons hold jacks, snappers, barracudas, puffers, parrotfish, moray eels, and sharks, including bull sharks that appear occasionally at the deeper ranges. Giant schools of these species regularly sweep through the site. Whitetip reef sharks rest on the bottom and are seen on the great majority of dive trips here. Spotted eagle rays cruise mid-column in pairs or small groups, and the site is noted for its high concentrations of large pelagic species generally.
