In the southeastern section of Ikaria near the village of Katafygi nad just below the Rock of Paroufa, you’ll find the Cave of Semni. This cave runs from northwest to southeast, and is difficult to access due to the dense vegetation surrounding it. It’s a small cave, with a length of only 4.1 metres and a width of 1.5 metre. There are no stalagtites and there has yet to be an archaeological or speleological investigation done at the cave.
