The Olle 18 course is an easy 3-4 hour walking course that goes around Sangebi to Sarabong, Wondangbong, and Seoubong, and goes through the sea road to historical sites such as Jocheon Manse Hill.
Olle Trail Route 18 starts at the old Downtown of Jeju-si near Dongmun market, and finishes at Jocheon Manse Dongsan. If you have time, you can take it easy, and look around the traditional market before starting.
A surprisingly worth walking courseCoastal road leading from downtown Jeju to JocheonSanjicheon (山地川) is a stream that flows across from the entrance to Dongmun Market, the busiest street in Jeju City. In the 1960s, when industrialization was in full swing, Sanjicheon was covered and houses and commercial buildings were built, causing problems of environmental pollution. In 1995, a restoration project was started to restore Sanjicheon to its cultural and historical appearance, and in 2002, the water returned to clear water. It now has the appearance of a flowing mountain stream. Currently, freshwater fish such as silverfish, mullet, yellowtail, and carp live in the waters of Sanjicheon, so you can often see people enjoying fishing and children swimming in the summer.
