Breathtaking Mediterranean sea caves you can explore during a yacht rental

As its name suggests, this sea cave is celebrated for its bright blue waters. The light comes from a large underwater opening located under the entrance of the cave. First discovered in Roman times, the Blue Grotto is said to have been decorated with many ancient statues and served as a swim basin for the Emperor Tiberius. Later on, legends suggested that the cave was inhabited by evil spirits. Rediscovered in 1826 and now the emblem of the island of Capri, the Grotta Azzura is one of the top things to do in Capri during your Amalfi Coast yacht charter.

The Neptune Caves are a required stopover during a Sardinia yacht charter. These rock formations are located in the Capo Caccia area and are one of the most precious geological wonders of the Mediterranean. The cave is complex with many galleries, rooms and lakes with clear waters. It is possible to admire stalactites and stalagmites that can reach up to 20 meters in height. Don't miss the Organo room which takes its name from an organ-like stalagmite. It can be reached by boat or by a picturesque 654-step staircase.

The Blue Caves of Zakynthos Island consist of a series of geological formations spread along white cliffs just below Cape Skinari. The natural arches created by erosion are of striking beauty and the reflection of light on the sea results in an unreal blue colour. We recommend that you visit the caves early in the morning or at sunset. The crystal-clear water and marine life make this place a great snorkelling spot if you want to enjoy some extra activities during your Greece yacht charter in the Ionian islands.

Discovered in 1951, this sea cave is located on the island of Kefalonia in Greece and takes its name from Greek mythology: the nymph cave. The cave boasts a brackish water lake. Surrounded on one side by a mountain slope and on the other by a forest, the place is simply magical and you must absolutely stop there during your yacht charter in Greece. Part of the cave is open-air, and the other is lit by electricity. The color of the water is changing depending on the sun's rays. Noon is the ideal time to visit the cave because the sun is directly overlooking the waters.

The Modra Spilja cave is one of the natural wonders of the Adriatic. Located in a small cove on the island of Bisevo, the cave draws its bright blue shades from an underwater passage through which the magical play of light becomes possible. Formed by the waves, the sea cave originally had only an underwater access. An artificial entrance was subsequently created to facilitate access by boat. A visit not to be missed during your Croatia yacht charter.
