The Blue Lagoon sits two nautical miles southeast of Ayia Napa, where the limestone shelf of Cape Greco drops into the Mediterranean in a series of submerged terraces. Water depth rarely exceeds six metres across the quarter-kilometre basin, and the white marl floor reflects midday sun back through the column, producing the cyan gradient that gives the site its name. Geologists attribute the lagoon's formation to karstic dissolution during the Pleistocene, when sea levels stood forty metres lower and freshwater streams carved channels through the porous Koronia formation. As the ocean rose, those channels flooded, leaving a network of shallow bays and submerged caves along the cape's eastern flank. Commercial boat departures from Ayia Napa Harbour began in the early 1990s, coinciding with the resort's expansion as a Mediterranean beach destination. By 2010, the Blue Lagoon had become the single most-visited offshore site in the Famagusta district, with operators recording over eighty thousand passenger trips per season. The Cypriot Department of Fisheries and Marine Research designated the surrounding waters a protected zone in 2018, limiting anchor drops to sandy patches and restricting vessel speeds within five hundred metres of the shore. Cape Greco itself—a windswept promontory of scrub and limestone—was declared a national forest park in 1993, and its sea caves, accessible only by boat, remain one of the coast's signature geological features. Most ayia napa boat trip blue lagoon tours follow a clockwise route around the cape, departing between nine and ten in the morning to reach the lagoon before midday crowds. Vessels range from fibreglass day cruisers seating thirty passengers to twin-hulled catamarans equipped with shade canopies and swim platforms. The standard itinerary includes a swim stop at the Blue Lagoon, a second anchorage at Turtle Cove—where loggerhead turtles nest between June and August—and a slow pass beneath the sea caves, whose vaulted interiors amplify the sound of wave surge. Some operators extend the route north to the Famagusta coast, adding a barbecue lunch and a third swim stop near Protaras. The tours return to Ayia Napa Harbour by late afternoon, completing a circuit that covers roughly twelve nautical miles and lasts between four and six hours, depending on the number of stops and sea conditions.
