Transparent waters thanks to Posidonia

Formentera is the ideal island to relax with snorkeling excursions, thanks also to the very few jellyfish present. Even if you happen to meet some of them, you will not find it difficult to avoid them since they can still be seen from long distances, thanks to the transparency of water.

This is the result of the perfect oxygenation accomplished by one miraculous plant, responsible for absolute transparency, or the Posidonia Oceanica.

In fact, it is located in the stretch that separates it from nearby Ibiza one of the Posi meadowsdonia longest-lived and largest in the world (about 8 km). This also explains why the characteristic leaves of this plant are present in many representations of the island (you can also admire a sculpture dedicated to Posidonia in one of the roundabouts of the capital Sant Francesc).

It seems only right to open an important parenthesis on this plant: throwing anchor above the Posidonia meadows means destroying a living being, vital for the balance of maritime life in these waters. The authorities try to sanction those who do not respect the marine ecosystem, but it is not easy, especially during the summer.

Where to snorkel in Formentera

There are several areas and beaches ideal for snorkeling in Formentera. We recommend some of them.

Sa Pedrera

If you like the rocky bottoms, the most recommended trait is the one that gives Sa Pedrera it extends up to the Gavina Tower, on the western side. Reaching it is not easy due to lack of indications, but in Formentera it is impossible to get lost, thanks to its small size.

Will find natural pools e enchanting depths not too deep, where you can admire many fish. On the other hand, if you try to throw a small piece of bread into the water in some places, you will see them rushing in.

It's Calo

With the mask and the rock shoes, you are ready to dive into the turquoise sea of It's Caló. Here the feeling will be that of flying in a blue sky, given how clear and clean the sea is. The farther you go from the urban center, the more the depth will increase (even close to the coast).

Ses Illetes

Ses Illetes, the most famous beach in Formentera is perfect for doing snorkeling even with the little ones, given the shallow depths. Sports enthusiasts can reach the islets ("illetes", in fact) that can be seen in front of the various beaches in this stretch, considered one of the most beautiful seas in the world!


Another argument should be made for the long beach of Migjorn, the splendid expanse of over five kilometers of beach, characterized by a turquoise sea with a thousand shades of blue.

In this infinite pool, snorkeling will give you moments of extraordinary beauty, however close encounters with many schools of fish (the same ones that, if you stay still, will nibble on your ankles).

We point out an interesting gem: in the initial part of Migjorn, at km 7 of the main road, the coast is characterized by small caves. This phenomenon is called in Catalan “codól foradat”, in reference to these curious ones perforated rocks.

Saône Cove

From what is believed the most suitable beach for families of Formentera (together with Es Pujols), you can easily explore the rock walls on the sides of the cove with the mask. Even here, despite being often very crowded, you can find and observe the inhabitants of the marine environment.
