On the southern tip of La Palma, the snorkeling at Faro de Fuencaliente is popular with local snorkelers. While most snorkelers will be off the main beach, if the waves are calm enough, you may be able to snorkel the rocks to the south of the lighthouse.
During La Palma snorkeling, you may encounter jellyfish, barracuda, stingrays, damselfish, trumpetfish, parrotfish, starfish and octopus. While the snorkeling off La Palma is good year-round, the water temperature is a little cooler in the winter and you may need a thin neoprene shirt.
Since the Canary Islands are actually part of Spain, the best way to fly to the islands is through an airport in Spain. There are flights to all of the main Canary Islands directly from one Spanish airport or another. Of course, Madrid offers the best connections. Presently, there are not direct flights from the USA to the Canary Islands. Once in the Canary Islands, the best way to go between islands is still by inter-island flights. There are some boat services that do go between the islands as well. TIP: For your safety, most of the Canary Island snorkeling dive sites require snorkelers to have a diver-down flag marker. The waters around the islands are very popular with windsurfers and boaters, which has resulted in some snorkeler deaths over the past few years.
Overall, Fuencaliente is the 23rd most popular snorkel dive spot of all 39 snorkeling dives in Canary Islands.
