Kefalonia Sights & Monuments - Katavothres in Kefalonia, Greece is a must-visit geological attraction located just 2 km from Argostoli, on the cape of Agios Theodoros. These remarkable sinks are natural openings in the ground next to the sea, which allows water to enter and follow a wide underground path across almost the entire island of Kefalonia. In a groundbreaking experiment, geologists Viktor Maurin and Josef Zötl from the Technical University of Graz dropped 160 pounds of paint into the sinks, and traces of the paint were found 14 kilometers away on the other side of the island, as well as in the Lake Cavern of Melissani. Don't miss the chance to witness the wonder of Katavothres, a geological marvel unique to Kefalonia, Greece.
