Sea caves (or littoral caves) are spectacular and more fascinating than other types of caves namely because they are part of Neptune’s watery and blue kingdom and hide unknown and unseen treasure. They’re formed as a result of erosion and the action of the sea waves. Quite often such caves “appear” along a present coastline near islands and are accessible by sea only.
Greek islands are dotted with several extremely beautiful sea caves, one of them being Papanikolis Cave. It is located in the sea of the island of Meganisi and is accessible from Nydri which is a small village on the white island of Lefkada. Although the cave is not a typical sea cave but a karst one, nowadays it’s inundated by the sea. There’re three interesting facts about the cave and here they are. During the Ottoman rule a priest called “papas” and his students and followers found a shelter namely in that cave and thus saved themselves from pirates. Later during the World War II the cave was used as a hideaway of the Papanikolis submarine after an attack over the Italian armada. In present times it is a preferred place and shelter for ships in bad weather because the cave is large enough and is about 30metres deep in order to accommodate big vessels.
Another sea cave is Grotta di Nettuno(or Neptune’s Grotto) and is situated on the island of Sardinia. It’s a stalactite cave found by a local fisherman about two centuries ago. Today it’s accessible by sea from the sea port of Alghero and the entrance is almost at the sea level (only a metre above it). On the other hand, there’s a stairway cut with more than 650 challenging, steep steps (known as goat’s steps) in the cliffs. These cliffs are called Capo Caccia and are 110 metres high. Grotto di Nettuno is impressive and offers a great number of cave formations as well as gorgeous views outside while “struggling” with the goat’s steps.
Italy has another famous cave, this time situated on Capri. Grotta Azzurra (or Blue Grotto) is 150 metres deep and is famous for its blue water all over the world. The blue and emerald effect is due to the lightening from the two sources. First, a brilliant white light comes from a smaller hole which is the entranceway of the cave. And second, a light penetrates from another bigger hole that is ten times bigger than the first one and is situated directly below the entranceway.
No matter whether you will choose the ancient Greek Kingdom of Poseidon or that of his ancient Roman counterpart – Neptune, the experience of being in a cave surrounded by water is a little bit dangerous but extremely challenging at the same time. So, never miss that chance and dive courageously into the water land of Neptunia (or Poseidonia, call it as you wish 😉 ).
