Casa del Mundo offers a unique freshwater diving experience featuring a combination of shallow reef, wall, and artificial reef structures. Divers can explore depths ranging from 5 to 18 metres, with an average depth of 12 metres. The site is accessible only by boat and is suitable for beginners, though the presence of an overhead environment and variable visibility between 3 and 10 metres requires careful navigation. Geothermal activity from volcanic vents creates localized hot spots on the lake bed, contrasting with colder water temperatures and thermoclines. Guided tours are recommended to manage these conditions effectively. Air fills, gear storage, and guided services are available on-site.

Hot Spring is a freshwater artificial reef site in Guatemala, defined by underwater geothermal vents that create a shimmering, layered effect as warm and cold water mix. Divers can explore the structure at depths ranging from 5 to 20 metres, with an average depth of 18 metres. Visibility typically fluctuates between 5 and 10 metres, often shifting unpredictably due to the thermocline. Access is by boat only, and a dive shop is available on-site for equipment and briefings. The site is suited for intermediate divers who should be prepared for cold water and variable visibility. The habitat supports general freshwater fish and invertebrates typical of the region.
