Bekiri's Cave on the west of the island, a stone's throw from Agioi Anargyri beach, is one of the major attractions on Spetses.
You can reach it by road or sea. However, you should know that neither way is easy. If you come by road, follow the path which starts with cement steps from the new pier on the north side of the beach, pass through the pine forest until you come to the new concrete steps that descend to the entrance. A recent landslide has made access to the cave difficult without blocking the entrance, though. If you come by sea, you have to enter the cave by swimming because of its low ceiling. You can easily see the entrance as there is a red indicator.
Once in the cave, the sight is rewarding! There are stalagmites, a small sandy beach and clear blue waters. There are several folk stories which over time relating to the name of the cave. One of the most relevant suggests that Bekiris, who was chased by the Turks and and hid there until he was found and killed, lived there. Another says many women and children saved from the Kasteli massacre during the 1770s sought refuge there. However, one Spetses resident called Bekris gave them up to the TurkoAlbanians. According to tradition, the Greeks stopped coming out of the cave when the sea was stained crimson from the blood of slain siblings.
