Pozo de las Calcosas
Pozo de las Calcosas is a good place to swim and features pools similar to those of Charco Manso, and a number of black stone huts on the ocean shore, all reached by steep steps.

This is perhaps the closest El Hierro has by way of a seaside resort. It has a small bay and you can travel out in boats as part of the fun-filled activities available.
