Sunken City of Olous

The ruins bay lies just south of the Poros causeway and opens directly onto the Gulf of Mirabello through a southeast-to-south window, the only sector carrying meaningful swell. The Kolokytha (Spinalonga) peninsula wraps around to block everything from the north through east — including the dominant northerly Aegean Meltemi — while the Elounda shoreline shuts down the west and southwest. Only southeasterly to southerly weather pushes wave energy up the gulf into these shallows, and even then the site stays calm and snorkel-friendly for most of the year.
