National Geographic Travelさんのインスタグラム写真 - (National Geographic TravelInstagram)「Photo by @jodymacdonaldphoto | The Kingdom of Tonga is an archipelago in the South Pacific that consists of over 150 beautiful tropical islands that have white sand beaches, breathtaking lagoons, and rugged coastlines. It’s also known for its volcanic activity, and it is the geological complexity of the area that has helped to create many hidden limestone caves that are exciting to explore both above and below the water’s surface. This particular cave is completely sealed from the outside world and is only accessible via an underwater tunnel. The filtered sun rays make the entrance glow with a vibrant light blue color and make for an exciting snorkeling excursion.
