Dive-site story
Lake Ilopango fills a massive volcanic caldera just east of San Salvador. Diving here offers an unusual freshwater volcanic environment characterized by submerged cliffs, steep drop-offs into deep abyss, and active geothermal vents where hot mineral water bubbles straight out of the lakebed. Volcanic ash, submerged rock pinnacles, and several deliberately sunken sculptures create distinct navigational landmarks along the perimeter.
Underwater geothermal fumaroles venting heated water and volcanic gases
Dramatic underwater cliffs and volcanic topography dropping into deep water
Submerged religious statues and artificial structures on the lakebed
Freshwater cichlids and crabs adapted to volcanic lake conditions
