Profile and sections
An active hydrothermal (hypogenic) cave: the surface layer is 19–21 °C, below ~6 m the water is 29–31 °C. You dive through a maze of parallel passages with colourful walls and fragile mud stalactites. The silt is very fine (locally >2 m thick) and visibility can drop to zero fast. The water is sulphate-rich and corrosive. The cave is diveable all year.
The cave has been explored since 1974; the Cueva del Agua LIMITE10000 group is working towards 10 km of survey.
- Depth and profile
- Max -34 m. 7,169 m surveyed (Dec 2024), ~95% underwater. Cavern zone ~60 m from the entrance (signs). Air chambers at ~500 m and ~800 m.
- Configuration
- Sidemount is most used for freedom of movement in the maze. Backmount and CCR possible in the larger passages (estimate). Water ~30 °C: thin wetsuit.
- DPV: Not DPV-suitable (estimate)
- Maze with fine silt and fragile formations: no scooter.
