Daejeon Dulesangil is a loop route (with one short out and back section to a high point) that follows the mountain ridge-lines that circle the city of Daejeon, South Korea.
It has 12 sections that are made to be done as 12 day hikes. It is an old trail at this point and much has changed over time. For example a bridge was built over the highway in one section in November 2020 and now the trail goes over the highway instead of around. Many signs are incorrect that have not been removed while new signs have been put in that confirm that the others are incorrect.
Most cities in South Korea have a Dulesangil trail. The one in Seoul is the quite popular.
