This dive site, Lago Ilopango, offers a unique diving experience within an active volcanic crater lake located just 16 kilometers from San Salvador, El Salvador. Formed by a massive volcanic eruption in 240 AD, the lake measures 8 x 11 km and has a maximum depth of 230m, though diving is typically conducted up to 22m. Divers explore extraordinary volcanic rock formations, dramatic underwater cliffs, and unique hot water springs, navigating along the contours of the volcanic structures.
The provided information does not specify marine animals or plants unique to Lago Ilopango. As a freshwater volcanic lake, the ecosystem would differ significantly from marine environments. Divers might encounter freshwater fish species adapted to the lake's unique conditions, but specific details are not available, suggesting the primary draw is the geological landscape.
The best time to visit Lago Ilopango is not explicitly stated, but year-round diving is often possible in such lakes, with local operators providing conditions updates. Divers should be prepared for varying water temperatures, especially around the hot springs, and potentially variable visibility. It's an excellent destination for those seeking a unique geological dive experience, and freedivers can explore the shallower areas and dramatic underwater topography.
