Jeju is an island lying off the southern tip of South Korea, in a body of water known as the Korean Strait. At over 1.8k square km (about 700 square mi), it is the country's largest island. The island's volcano and lava tubes are a UNESCO World Heritage natural site. In this beautiful video, contributor Majestic used a drone to film this exotic island. The video shows the blue-green waters, sprawling beaches, and a small wind farm located off the shore of the island.
