A short walk or quick drive east of the village brings you to a steep limestone headland with the layered remains of one of the oldest settlements in the Argolid. Mycenaean walls at the base, classical Greek courses above, and on top a Venetian fortress that incorporated the older stone.
It is not a manicured archaeological park — paths are rough, signage minimal, and you can essentially wander where you like. The views over the gulf and back to Tolo's beach are among the best in the area. Open during daylight, free entry.
