El Golfo is a natural amphitheatre open to the sea which was formed from the volcanic eruptions of 1730. The lagoon, which fills the base of this semicircular crater, is a result of flooding, and its green colour is from the algae that inhabit its waters.
The volcano made of porous lava ash has through the action of time given rise to spectacular formations.
The sea connected underground, passes through the crater forming a beautiful black beach, which contrasts with the green lagoon.
This lake has been declared a Natural Reserve which prohibits bathing.
It is located in the south of the island in the Municipality of Yaiza.
The village of El Golfo can be found a few metres away, where you can enjoy various restaurants facing the sea.
