Casa del Mundo
Why dive here
Casa del Mundo is a cave dive where divers can encounter humpback whales and sea turtles. Water sits around 28°C.
Diving Casa del Mundo in Lake Atitlan is definitely a unique experience, more about the novelty than a riot of marine life. We usually boat out to this spot, dropping into the cool, freshwater. The main draw here is the volcanic activity; push your hand into the sandy bottom around 10-12 meters and you’ll feel the warmth from the earth itself. Visibility averages around 4 meters, so it’s an intimate dive, perfect for divers looking for something a bit different, rather than a coral spectacle. You might spot a few Mozambique mouth-breeders darting amongst the submerged rock formations, but really, it’s all about feeling that geothermal heat.
