A brisk 20-minute speedboat run peels away from Marathon Beach and the pines of Schinias, the sea opening like a cool, breathing presence that dares you to dive in. In small groups of seven, the boat slips into glassy coves and over rocky shoals where seagrass beds and scattered boulders create pockets of life; fish investigate your shadow and occasional rays of sunlight braid through the water column.
