Dodu Bong is a low, cone-shaped parasitic volcano 63.5 meters above sea level on the coast of Dodong in Jeju City. From the summit, planes take off and land on the Jeju Airport runway, and the Jeju sea and Hallasan are visible together, along with a Kisses-shaped photo zone. From the parking lot next to the Rainbow Coastal Road, the fast route to the summit takes 5 to 15 minutes, while the circular trail takes about 30 minutes. The fast route up the stairs is steep.
