Visitors can experience the thrill of a hidden and beautiful upside down world, made of breath-taking scenery, rich in extraordinary concretions, where the silence is broken only by the dripping of the drops of water that bring the constantly changing complex to life.

There are two adventure trails – the blue trail (for those over the age of 12) and the red trail – which allow small guided groups to pass through underground passages, narrow pathways and shafts and admire splendid rooms concealed from the gaze of “normal” tourists.

The basic admission is 15,50Eur / person.

Inside Blue Grotto, Capri, Italy by Jun

Located at the waterline inside the cave, a hole in the wall of the cave that is only one and a half meters in diameter allows the sunlight into the Blue Grotto. This is also just large enough to allow a small rowboat into the cave. Below this small hole is an even larger hole which allows the light to reflect on the base of the cave beneath the water line. As a result, the water in the Blue Grotto emits this eerie blue glow.

Inside of the Blue Grotto, many marble statues were found back in the early part of the 1800s. There was also a landing spot inside of the cave which means that they Blue Grotto was well known even back in the days of the Roman Empire. Today, this cave is the symbol of the Island of Capri and is the number one reason why people make their way to the island every single year.

Entrance to Blue Grotto, Capri, Italy by Arnaud Gaillard

To enter the cave, one must transfer to a wooden boat that is oared into the Blue Grotto. Since the size of the hole is so small, when entering the cave, you will have to lay flat on your back so as to prevent hitting your head. However, the inside of the Blue Grotto is very spacious. Furthermore, if there are any trough seas, access to the caves are limited because the rowboat can barely fit through the small opening in a calm sea.

During the peak season, when the conditions are just right, it is not uncommon for traffic jams to occur as the boats take turns entering and exiting the cave. However, for those who are brave enough, in the evenings after the rowboats have gone for the day, it is possible to swim into the Blue Grotto. Special precautions must be taken so as not to get slammed into the edges of the opening by the waves.
