Above Katavolos on an anonymous rock two Graves caves are located. In the past the
upper Graves cave was used as a corral.
In 2018 two attempts were made to find access to the Graves caves. Further exploration was required. In
April 2019 it became clear that there is no possibility to enter the cave. The vegetation is dense and impenetrable. Close to the cave are some ruins are located. Probably the residents kept
their sheep or goats in the cave and when they left the area, the cave became inaccessible.
