Freshwater lake dive in Coatepeque's volcanic basin
Local lake operators and boat support are the practical way to reach the site.
Freshwater lake dive in Coatepeque's volcanic basin, where the appeal is the submerged crater-lake landscape rather than reef structure. The route feels slow and scenic, with a measured loop around submerged domes and unusual underwater relief that rewards calm-water days, good trim, and time spent looking at the rock-and-wood formations rather than covering distance.
