Seoul city has completed building the "Seoul Dulegil", a 157 km trail on which visitors can explore culture and natural ecology along with mountains and rivers in and around the city.

Seoul said it will on Saturday open the entire route of the Dulegil which it began building in 2011 with a goal to create a trail for people and nature.

The Seoul Dulegil comprises eight courses including the Mt. Surak and Buram course, the Mt. Yongma course, the Mt. Godeok and Ilja course and the Anyang Stream course.

To boost usage of the trail, the city said it will issue certificates to those who complete all of the eight courses and get rubber stamps from the 27 stamping stations made from recycled mailboxes along the trail.
