Nagannu Island is a small, uninhabited island located approximately 15 kilometers west of Naha, Okinawa. It is celebrated for its natural beauty, offering visitors a pristine environment to enjoy marine activities and relaxation. The island is part of the Kerama Islands National Park, known for its exceptional water clarity and vibrant marine life, making it a significant destination for eco-tourism and nature enthusiasts.
Visitors frequently highlight the island's crystal-clear waters, often described as 'incredibly clear,' which are ideal for snorkeling and diving. The beaches are primarily composed of coral and shell fragments, giving them a distinct white appearance, though some visitors note they are not as soft as typical sandy beaches. The opportunity to see coral reefs and potentially sea turtles is a major draw. Many reviewers appreciate the island's tranquil atmosphere, providing a peaceful contrast to the busier areas of Okinawa.
For a comfortable visit, it's advisable to bring reef-safe sunscreen, a hat, and water shoes to protect your feet from the coral fragments on the beach. Most visitors spend 3-5 hours on the island, which is sufficient time to enjoy swimming, snorkeling, and relaxing. It's recommended to visit in the morning to make the most of the daylight and avoid the peak heat of the afternoon. Consider bringing your own snacks and drinks, as options on the island might be limited or more expensive.
Access to Nagannu Island is exclusively by boat. Ferries depart from Tomari Port in Naha, with the journey taking approximately 20 minutes. Many visitors opt for half-day tours that include round-trip transportation, often departing in the morning and returning to Naha around 3 PM. Tomari Port is accessible via public transport in Naha; check local bus routes or use a taxi service to reach the port.
A common point mentioned by visitors is the coral-fragmented beaches, which, while beautiful, can be rough on bare feet. Wearing water shoes is highly recommended to mitigate this. Additionally, as an uninhabited island, facilities might be basic, so coming prepared with essentials like water, snacks, and sun protection is crucial to ensure a pleasant experience.
