The Seongsan Ilchulbong certification center sits across from Seongsan Ilchulbong in Seogwipo and stamps the Jeju Fantasy Bicycle Path passport at the eastern end of the route. At the Seongsan Ilchulbong ticket office, the path splits into a paid trail up to the peak and a free trail that runs below, and reaching the peak requires buying a ticket. A restroom is directly across from the center, restaurants are nearby, and the center has a space where cyclists can rest. Seongsan Ilchulbong is a geological formation built up in layers as volcanic ash combined with moisture.
