A special defense unit of the Goryeo kingdom rebelled against the invading Mongolian army in 1270, and eventually retreated to Jeju Island for a last stand. They held off the Mongolian forces here for 2 years before they were all killed at a fortress built here.
The Historic Site of Anti-Mongolian Struggle, also known as the Historic Site of Anti-Yuan Struggle and the Hangpaduri Hangmong Historic Site, is a protected area in Jeju Province, South Korea, that was once the location of an earthen fortress. This fortress, the Hangpadu/Hangpaduri Fortress, was built in 1271 by the Sambyeolcho rebels, who opposed the surrender by the Goryeo dynasty ruling Korea to the Yuan dynasty following the Mongol invasions of Korea. Built shortly after the Sambyeolcho took over the island of Jeju, the fortress soon became the capital of the rebellion after the Sambyeolcho were defeated elsewhere. Together with the Hwanhaejangseong coastal wall and various village fortifications, the fortress formed part of a defensive system to protect the island. After the Sambyeolcho forces were defeated by a combined Goryeo-Mongol invasion of 12,000 soldiers in 1273, the site eventually fell into disuse.

It is close to Jeju Airport, and it is enough distance to ride a bicycle. There are white and red pony lighthouses, the slope of the beach is gentle, and there is a pine forest nearby, so it is a good place to enjoy the scenery and take a walk.
신비의 도로
Called the Mysterious Road or the Goblin Road, this is a strange place where if you park your car on a downhill road, the car that has to go down does not go down, but rather steps back toward the uphill. In fact, the side where the uphill road is visible is a downhill road with a slope of about 3 degrees, so it seems to be going up by a simple optical illusion. Due to this phenomenon, Dokkaebi Road has become a tourist attraction due to word of mouth, and various safety facilities are being added (as of Oct 2022) to prevent accidents caused by it, and a tourist park is expected to be created soon.

The Jeongwol Daeboreum Fire Festival originates from the traditional harvesting of the grasses found in the local domestic farm animal pastures, which were annually set in fire each winter by the villagers as a way to exterminate harmful insects. It has been held annually since 1997. It is held during the holiday of Daeboreum (which is the 15th day of the first lunar month of the year, typically February). It gets extremely busy directly after the festival finishes (19:00-20:00), so it's sometimes worth staying around for a beer or a meal for an hour or two until the worst of the traffic has gone.
