The rock of Kalogiros (meaning “Monk”) is one of the peculiar and impressive geological sights of Milos. On the northern coast, near the village of Pollonia you will see a cone-shaped lava rock, created less than 1 million years before present. The rock consists of standing pentagonal and hexagonal columns of rapidly-frozen lava formed. Similar rocks can be found a few hundred meters from Kalogiros on Glaronisia islets (meaning “Seagull islands”). Both are frequented by sailboats and are photographed closely by visitors in the summer. Kalogiros is also an interesting spot for divers, as the near-vertical slopes of Kalogiros dive into the beautiful Aegean Sea, forming tens of caves and interesting reefs.
