Following are links to Strava rides in South Jeolla Province, and brief descriptions of each course.
Naejangsan National Park – One of the most scenic places I’ve ridden in Korea and with very little traffic. This route started and finished in Damyang, but those points can fairly easily be altered. Highly recommended route!
Namwon – Yeosu: This is a great 150km route that begins at the Namwon bus terminal and ends at the Yeosu bus terminal. The route transverses Jirisan, which is the biggest climb of the Korean mainland, gaining 1,018m over nearly 14km.
