Though much of the coast of La Palma in Spain’s Canary Islands is steep and rocky, you’ll still find gems such as black beaches, underwater caves, and natural pools. The latter is best exemplified at La Fajana, a set of three depressions in the volcanic rock that flood at high tide and retain the water.

People have been soaking in these pools for centuries. The natural formations have even been modified to suit visitors, with additions such as a flat walking surface and handrails completed. These modifications are important, especially during high tide, when the waves smash the rocks with quite a tremendous force. 

The watery wonders offer a unique insight into the local flora and fauna. The pool beds are covered with algae, making it quite slippery. Various species of fish either get trapped in the pools or stay there of their own free will to avoid predators. One species in particular is loved among tourists, as they nibble at the dead skin on your feet.
