Gayasan Sori-gil is a 6-kilometer walk from Hapcheon Theme Park of the Tripitaka Koreana to Yeongsangyo Bridge, near Haeinsa Temple (one of the three major temples in Korea), which restores the old Hongnyu-dong path. This route allows you to stroll along the valley, where you can listen to the sounds of water, birdsong, and immerse yourself in the natural beauty of Korea. Along the way, you can visit some of Gayasan's stunning locations, including Nongsanjeong Pavilion, Gilsangam Hermitage, Nakhwadam Reservoir, and a red clay trail.
