Among the numerous natural pools that can be enjoyed in El Hierro is the Pozo de las Calcosas. This swimming area is located in the northern part of the island, next to the village of El Mocanal, about 5 kilometers from the capital Valverde, in a small natural bay which is closed by a cliff. The pools have dimensions of 20 meters long by six wide. Around the wells there are some constructions that are part of a coastal town that maintains the type of ancestral construction: high roofs, plant material, etc. These houses were built by local fishermen to spend the summer months.

In the area of the Pozo de las Calcosas can be seen perfectly as a language of solidified lava and its whimsical shape give rise to the formation natural pools. They perfectly distinguish the folds of volcanic material that slid through the rugged area, a spectacular way to discover how this natural space was formed.

Access to the wells must be done on foot along a path that runs along the cliff and down several flights of stairs from the nearby parking area. The path that descends to the natural pools is an easy and short trail, also allows you to enjoy spectacular views of the ocean and the rugged coasts of the island of El Hierro.

It is also curious the sculpture in honor of the god Neptune, that was made in 2007 with recycled materials and brings much more symbolism to this curious place.

The situation of the swimming pools, the small nearby village of El Mocanal, the peace and serenity that is breathed, the sound of the waves or the clean and transparent waters of the coast They make this corner a practically magical place and a must visit.
