Pounta Port sits on the southwestern coast of Paros, a narrow concrete quay where fishing boats and passenger ferries share mooring space with the wooden kaikis that carry day-trippers to Antiparos and the Blue Lagoon. The lagoon itself is not a named geographical feature on nautical charts but a stretch of shallow, sand-bottomed water between the southeastern tip of Antiparos and the uninhabited islet of Despotiko, where the seabed drops away so gradually that you can wade thirty metres from shore and still stand chest-deep in water the colour of backlit aquamarine. The pounta blue lagoon boat tour paros became a fixture of the island's summer calendar in the early 2000s, when local operators began offering half-day excursions to compete with the crowded beaches of Naoussa and Golden Beach. Unlike the larger cruise vessels that depart from Parikia, the traditional wooden kaikis that leave from Pounta Port carry smaller groups—typically twenty to thirty passengers—and follow a route that hugs the western coast of Antiparos before rounding the southern cape and anchoring in the lagoon's shallows. Most itineraries include a second swimming stop at Panteronisia, a cluster of three rocky islets where the water deepens abruptly and schools of bream gather beneath the hulls. Despotiko, visible from every point in the lagoon, remains archaeologically significant. Excavations since 1997 have uncovered the sanctuary of Apollo, a sixth-century BCE temple complex that served as a pilgrimage site for sailors crossing the central Cyclades. The ruins are not accessible to boat passengers—visitors require advance permission from the Ephorate of Antiquities—but the stone foundations are visible from the water, particularly the rectangular outline of the main temple on the island's low eastern ridge. The Blue Lagoon's appeal is strictly natural rather than infrastructural. There are no facilities on Despotiko, no permanent moorings in the lagoon, and no shade beyond the occasional umbrella staked into the sand by early arrivals. Water temperature in summer holds steady between twenty-three and twenty-six degrees Celsius, warm enough that most swimmers spend an hour or longer in the water. Visibility averages fifteen metres on calm days, and the seabed is a mix of fine white sand and scattered beds of Posidonia seagrass, the latter a protected marine species that contributes to the water's exceptional clarity. Operators anchor their kaikis in four to five metres of depth and lower swim ladders; passengers either wade to shore or swim directly from the boat.
