Cheonjaeyeon Waterfall is a breathtaking sight bathed in enchanted lore. Legend has it that seven nymphs descended from heaven at midnight to bathe in the waterfall's pool. Explore the heavenly waterfall cascading from a 72-foot (22-meter) cliff as well as the surrounding forest, and walk across the arched bridge that features carvings of the seven nymphs.
Thanks to Halla mountain (Halla-san in Korean), the island of Cheju exists today. The once-active volcano is now the highest mountain in South Korea at 6,398 feet (1,950 meters) with a crater lake at its summit. The mountain displays all four seasons with flourish: bright azalia blossoms in spring, thick green forest in summer, ablaze with crimson leaves in fall and blanketed with snow in winter. Hike one of five trails to encounter some 1,800 varieties of plants, including rare and endangered species, and take in the bird's-eye views of the clear-blue crater lake and the surrounding tropical island.
For authentic Cheju island goods, visit the Jeju Folk Arts Complex, where craftsmen practice their trade and display their art. For more traditional ware and the opportunity to walk through historic and re-created buildings, visit the Jeju Folk Village. It features mountain fishing and religious villages, as well as agricultural displays and a marketplace.
