Visit Japan Web Blue Cave
Visit Japan Web invites you to explore Blue Cave near Onna village. It is the prime spot for novice divers to immerse themselves in the enchanting marine life. Despite common misconceptions, even non-swimmers have the chance to experience the awe-inspiring underwater world through guided tours.
It is not difficult to comprehend the origin of the cave’s name. A sparkling blue radiance from sunlight bouncing off the white ocean floor illuminates the interior. Diving or snorkeling is possible throughout the year, but the optimal time to visit is between May and October. During the summer months, it can get crowded, so it’s advisable to make reservations in advance and be prepared for queues.
For more experienced divers, the nearby Manza Dream Hole is an excellent option. Dive from a boat and descend approximately 10 meters to reach the cave entrance. As you descend to around 30 meters, you’ll encounter sweeperfish, garden eels, fan coral, and more. If these depths seem a bit intimidating, the adjacent Mini Dream Hole is equally stunning but only half as deep.
If you prefer to observe the underwater world without getting wet, consider visiting Busena Marine Park. It is located about a 30-minute drive north on route 58. Here, there’s an underwater observatory offering a 360-degree view of the coral-dwelling creatures, including clownfish, Hawaiian ornate butterfly fish, and the Moorish idol.
For an even more intimate experience, you can embark on a glass-bottomed boat tour into the bay. Here, visitors can enjoy breathtaking views of the crystal-clear waters, stunning coral, and vibrant fish. The boat excursion typically lasts around 20 minutes. It allows visitors to have an up-close encounter with the fish that may make you feel like you could reach out and touch them.
