Cyprus's water experiences run along a 782-kilometre coastline of Mediterranean clarity. Paphos sea cave boat tours along the Akamas Peninsula — where the sea caves, the Blue Lagoon cove accessible only by water, and the Adonis Baths riverine gorge combine into a half-day coastal circuit — are the most visually rewarding. Larnaca Zenobia wreck diving — a 178-metre cargo ferry sunk in 1980 and rated one of the best wreck dives in the Mediterranean — and Ayia Napa coastline boat tours past the sea stack and cave formations of the Cape Greco national park add diving and coastal options. Sunset sailing tours from Limassol Marina, traditional caïque fishing boat experiences from Kyrenia harbour in the north, and glass-bottom boat tours above the Protaras and Pernera coral gardens complete a water programme of Mediterranean quality.
