El Hierro is not characterized by big extensions of beach; its coast is very abrupt, this is why they have created a series of natural pools for swimming, such as the ones in La Caleta or in La Maceta.
The pools of La Maceta are a few kilometers away from the airport and the capital, Valverde. It is a natural area for swimming, where the water from the sea has “dammed up” in a sort of conditioned pool. Next to the pools there is an area for lying in the sun, and you can also swim in the sea if you go down the stairs (although the waves are quite big).
The entire “construction” is perfectly integrated with the natural surroundings.
