Tenerife

The north coast of Tenerife is rugged and lined with cliffs formed by ancient lava flows. In places this coast offers some unusual spots for swimming, for instance the Charco de la Laja, in the seaside district of San Juan de la Rambla. A track by the sea takes you to a natural pool created by the remains of a lava flow that reached the sea. The Charco de la Laja is suitable for swimming but sometimes you need to take care due to the big waves.
