Only a jameo reveals the presence of volcanic passages and allows their routes to be traced. The Jameos del Agua was artistically developed for viewing by César Manrique in 1968.

Through a winding staircase visitors enter into the Jameo Grande, a roofless volcanic bubble 100 m. long and 30 m. wide, and from there into a magnificent garden with a large swimming pool.

At the foot of this cave is a large stage that extends into the next volcanic bubble called Jameo de la Cazuela, the latest to be made accessible to the public.

A few native and non-native species of animals live here some permanently, others temporarily. The most emblematic is the blind albino crab, a rare and delicate marine crustacean.
