Located in the deepest part of the Seoraksan Mountains, Gayadong Valley is a smaller valley compared to others in the region, with quiet streams. The walkway to Gayadong Valley starts from the path behind the Suryeomdong shelter. Walk up for 30 minutes and you will find the water flowing from Ose Waterfall. In front of it are the 40m high cliffs called the Cheonwang Gates, which are regarded as the gates of Gayadong. Past Cheonwang Gates is the Cheonwang Waterfall, and one kilometer up from this waterfall is Waryongyeon. Above Waryongyeon is the Neoreok Rock. If you walk further up there is a crossway. The old path to Oseam is on the left and the path to Bongjeongam, these days called Tapgol, is on the right. If you want to see the whole landscape, stop by at Mangyeongdae on the way to Oseam, and if you keep going up you will soon reach Muneomi Ridge. At Muneomi Ridge the path is divided into two of which one leads to Bongyrong Ridgeline and the other to Cheonbuldong Valley. If you want to climb to Daecheong Peak of Mt. Seoraksan, walk past the Huiungak shelter in the Socheong Peak and Jungcheong Peak direction. The Gayadong Valley has convenient paths, but there are no signs, and no iron ladders prepared yet. So compared to Cheonbuldong Valley where numerous people go hiking, you will prefer the mountain landscape in the serene atmosphere.  

Hangnimsa Temple was built to serve Buddhist nuns. While its origin is unknown, it is said to have been built undernear the Hakbawi Rock on Seohaksan Mountain about 600 years ago. The temple had deteriorated over time, but was rebuilt in April 1965 and renamed Anyangsa. The name changed again to Hangnimsa after the Daeungjeon Hall and the dormintory were rebuilt in 1985.  

The Jeju Mysterious Road, also known as Dokkaebi Road, lies on a hill at the foot of a mountain, and connects two major highways on Jejudo Island. It has earned its name, as objects and liquid appear to roll and flow up the hill instead of down, when, in fact, such image of gravity defiance is an optical illusion rendered by the seemingly high surroundings.
