Dodong Coastal Trail (도동 해안산책로)

Dodong Coastal Trail leads to Jeodong Coastal Trail, and together, they form Haengnam Coastal Trail. Dodong Coastal Trail corresponds to section 1 of Ulleung Haedam-gil (2.8km) and is also known as the Coastal Trail 34 course. There is a walking trail with a rainbow bridge and LED streetlights with the geopark logo, making it an attractive geological site among tourists.
Various geologic structures formed by early volcanic activity on Ulleungdo Island can be observed on the Dodong Coastal Trail. There is a gradual decrease in the age of rock formations as you go from Dodong Port to Dodong Lighthouse. Basaltic lava flows, Clastic sedimentary rocks (rocks made up of pieces transported by landslides), ignimbrite (a volcanic rock formed by the consolidation of material deposited by pyroclastic flows), and trachyte (an extrusive igneous rock) can be found from bottom to top.
