Agua Caliente is one of those dives that sticks with you not for big pelagics, but for its sheer oddity. It’s essentially an underwater hot spring vent, pumping out warm water from the lakebed. We typically descend to about 10-12 metres and feel the temperature shift dramatically. You’ll spot the ubiquitous Mozambique mouth-breeder, often hovering right in the warmer currents. Visibility hovers around 4 metres on a good day, so it’s a close-up encounter, a place for divers who appreciate the quirky side of underwater exploration rather than wide-open vistas.
