The first cavern you reach at Jameos del Agua resembles the nave of a vast marine basilica. Molten lava seethed through here en route to the sea, but in this case the ocean leaked in a bit, forming the startling azure lake at the heart of the Jameos. Manrique’s idea of installing bars and a restaurant around the lake, adding a pool and a concert hall seating 600 (with wonderful acoustics) was a pure brainwave.
Have a closer look into the lake’s waters. The tiny white flecks at the bottom are crabs. Small ones, yes, and the only known examples of Munidopsis polymorpha (blind crabs) away from the deepest oceans. Do heed the signs and resist the temptation to throw coins into the water – their corrosion could kill off this unique species. Access for the mobility impaired is not really possible as there are a lot of steps.
From July through September concerts are held on Tuesday and Saturday evenings.
