The Gyejoksan Mountain Red Clay Trail is an eco-healing walking trail which can be found on the nation’s first mountain with a barefoot walking theme, Mount Gyejok. In 2008, it was considered as one of the ‘33 travel destinations to go back to’ by travel journalists. About 500 children from 100 different countries who took part in the United Nations Children's Conference on the Environment, and Republic of Seychelles President James Michel have also gone barefoot walking on Mount Gyejok. Visitors can walk on red clay and breathe in the fresh aroma of pine trees while enjoying a view of downtown Daejeon from Gyejoksanseong Fortress, which was built during the time of the Three Kingdoms. The trail helps restore the health of the body and soul and gives visitors a therapeutic and unique experience. This 14-kilometer long trail is situated at an altitude between 200 meters and 300 meters above sea level. In autumn, the mountain is bustling with bikers who come to enjoy the splendid landscape of Mount Gyejok. Every year the Eco-Healing Sunyang Masai Marathon, which requires participants to forgo shoes and traverse soft red clay trail, is held at Mount Gyejoksan in Daejeon, drawing a total of 5,000 participants including 600 foreigners from 40 countries. The marathon has established itself as a major festival of Daejeon and is held every year in May.
