The occasional trail is a typical hiking route in Korea. Olle is a Jeju dialect, which means "the path in front of the house" in Korean. It's like a sheep intestinal path full of climbing vines and small flowers at the door of a country farm. Occasionally, the paths include hills surrounded by green bushes, coasts stretching for tens of miles, clean roads with flowers, country paths scattered like ribbons... Step on "Occasionally" and the salty sea breeze rushes towards you. Follow it, you can see the most beautiful Jeju. Occasional Trail is a famous scenic spot in Jeju, South Korea. It is known as "the most beautiful and peaceful path". In 2007, after the opening of the first "occasional path", it attracted many hikers. So far, more than 20 trails have been developed, ranging from 5 km to 20 km. These trails are winding between hundreds of coastal towns with beautiful scenery on both sides. Because Jezhou Island is formed by volcanic activity, the scenery in the southeast and northwest are different, and these routes also have their own beautiful encounters.
