The Kerama Islands, located approximately 40 kilometers west of Okinawa's main island, are a designated national park celebrated for their pristine natural beauty and exceptionally clear waters. Often referred to as 'Kerama Blue,' the ocean surrounding these islands boasts some of the highest transparency in the world, making it a globally recognized destination for marine activities.
Visitors consistently highlight the stunning underwater visibility and the abundance of marine life as the primary draws. Reviewers frequently describe diving and snorkeling experiences as 'outstanding' and 'beautiful,' emphasizing the vibrant coral reefs and diverse fish species. The islands are also a significant whale-watching destination, particularly from January to April, when humpback whales migrate to the warmer waters. Many visitors express a deep sense of wonder and relaxation, noting the islands as a perfect escape from urban life.
To make the most of a visit, it's advisable to book tours for diving, snorkeling, or whale watching in advance, especially during peak seasons. While the suggested duration is 3-4 hours, many visitors recommend spending a full day to fully immerse oneself in the activities and enjoy the tranquility. Bringing sun protection, swimwear, and a waterproof camera is highly recommended. For whale watching, consider bringing binoculars and motion sickness medication if prone to seasickness.
Access to the Kerama Islands is primarily by ferry or high-speed boat from Tomari Port in Naha, Okinawa. The journey typically takes about 40 minutes by high-speed boat to islands like Zamami or Tokashiki. Public transportation within the islands is limited, so many visitors rely on rental scooters, bicycles, or local buses/taxis arranged through their accommodation or tour operators. It's crucial to check ferry schedules in advance, as they can vary by season and weather conditions.
A common point for visitors to consider is the potential for crowded boats during peak season. To mitigate this, consider visiting during shoulder seasons (late spring or early autumn) or booking morning tours to avoid the busiest times. Some reviewers also note that while the main islands have amenities, the smaller, uninhabited islands are best explored with guided tours for safety and environmental protection.
