Dive-site story
Off the Huatulco coast, La Montosa Island holds volcanic reef built from tumbled granite boulders, shallow coral patches, and coarse sand channels. Divers navigate rock formations encrusted with barnacles, sea fans, and hard Pocillopora coral heads. The leeward side stays sheltered, whereas outer reef walls meet Pacific swells where pelagic species pass.
Granite boulder formations with swim-through crevices and invertebrate life
Pocillopora coral patches with reef fishes and cleaning stations
Sea turtles and resting stingrays along sandy margins
