Wonderful nature reserve and historical monuments of Jeju Island Jungmun Resort. Tickets for the visit are very cheap (adult tickets are about 2.5 USD), and there are many beautiful hiking trails and monuments. You can learn about the myths of Jeju Island and the history of the American occupation of Jeju Island after World War II. I would have liked to come here again, but it rained later. It was so wonderful and perfect for exercising here! It is a place for children and the elderly. A short walk from the entrance via a flat road to the waterfall. We made this place the last place on our trip (late night) as the place closed later than any attraction in Seogwipo. Quite a romantic walk, we even met some couples here to take photos of their wedding.
