Plongée à Kerama Islands — Japan

The Kerama Islands are a national park archipelago 40 km west of Okinawa's main island, famous for 'Kerama Blue' — water so clear that 50-metre visibility is commonplace. Green turtles glide over pristine coral gardens while humpback whales pass through in winter. Day trips from Naha are popular but staying on the islands unlocks the best early-morning sites.
