This dive site, Casa del Mundo, offers a unique freshwater diving experience within the stunning volcanic caldera of Lake Atitlan. Divers explore steep cliffs adorned with small fresh-water reefs, leading down to a sandy bottom. The most distinctive feature is the opportunity to feel the geothermal heat by placing a hand in the sand at the base of the volcano, a direct interaction with the region's active geology. Navigation is generally straightforward along the cliff face and lakebed.
While not a marine environment, divers can expect to encounter various freshwater fish species and invertebrates adapted to the lake's ecosystem. The "small fresh-water reefs" likely consist of unique aquatic plant life and formations supporting diverse macro-life, although specific species are not detailed in the provided information.
The best time to visit Casa del Mundo is generally during Guatemala's dry season (November to May) for optimal weather and lake conditions, though Lake Atitlan is diveable year-round. Highlights include the incredibly scenic boat ride surrounded by massive volcanoes and thick jungle, the crystal-clear water, and the unique thermal sand experience. Both scuba divers and freedivers will appreciate the manageable depths and beautiful underwater landscape.
