Cruise south along the Athenian Riviera to Cape Sounio, disembark beneath the Temple of Poseidon, and swim at secluded islets only reachable by boat. This private five-hour outing pairs history, snorkeling, and a classic Greek sunset.
More ways to explore the area's outdoor wonders
The boat slips away from the Athenian shoreline and the city concedes to open water — wind skimming the deck, the sea daring you to look further. Over the next five hours the coastline unfurls: rocky promontories, narrow bays, and white-sand coves that only a boat can reach. A short tender brings passengers to shore at Cape Sounio, where a 5–10 minute, 30–60 meter climb places you at the ancient Temple of Poseidon, perched on volcanic rock and looking out over the Aegean.
