A Brief History

The Sikia Cave is located on the southeastern coast of Milos, near the village of Zefiria. The cave was first discovered in the early 20th century by a local shepherd, but it wasn't until the 1980s that it was fully explored and mapped. Today, the cave is open to visitors who can explore its many wonders, including its beautiful stalactites and stalagmites.

Geology of the Cave

The Sikia Cave is made up of volcanic rock that has been eroded by wind and water over time. The cave is part of a larger network of underground tunnels and chambers that were formed by volcanic activity in the area. The cave is also home to a number of unique rock formations that have been created by the flow of water over time. These formations include stalactites, which hang from the ceiling of the cave, and stalagmites, which grow up from the cave floor.

Amazing cave with calm waters and rich bottom. Access is only possible by small boat or boat. It is worth bringing masks with you to enjoy the seabed and see the schools of fish that inhabit the rocks. It also has a small area of sand.
