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.

Agua Caliente is a freshwater reef and drop-off site in Guatemala, offering beginners an introduction to wall-style diving. The site reaches depths of 15 to 18 metres, with an average depth of 17 metres. Divers experience mild currents and visibility ranging from 3 to 15 metres. A notable feature is the presence of geothermal vents that create distinct thermoclines and pockets of high-temperature water. Due to cooler temperatures at depth, a 7mm wetsuit is recommended. Access is strictly by boat to avoid dangerous surf conditions at the shore. Guided tours are available to assist with navigating the variable visibility and local conditions.
