This section is a 20-kilometer-long section that requires drinks and snacks as well as endurance. While walking along the stream of Imjingang River, visitors will be able to enjoy short and long columnar joints and a beautiful view of the Imjingang River.

This section requires thorough preparation as there are very few residents here. Starting from Sunguijeon Hall that enshrines four kings, including King Taejo of Goryeo, and 16 meritorious retainers, visitors can enjoy the columnar joints in Dongi-ri along Imjingang River. Herb Village offers visitors the fragrance of herbs and European elegance, as well as various views of nature through the fields, riversides, and hills of clean and clear Yeoncheon. As the spicy fish soup in restaurants near the Imjingang River tastes excellent, it is a bargain trekking course where visitors can enjoy all the fun of seeing, trekking, and eating.

The trail in the quiet forest continues more than 5 kilometers, offering visitors a unique experience. The section from Lohas Park through Daegwanggyo Bridge to Sintan-ri Station (former Gyeongwon Line Northernmost Point) offers the unique experience of walking along the embankment lane side to the Chatancheon Stream. In Lohas Park, wetlands have been created to allow visitors to enjoy beautiful lotus flowers that fill up the pond, and the area surrounding Sintanri Station located at the end of Tongilieum-gil sells duck with mountain herbs and barley rice dishes with wild herbs and vegetables that have gone viral.
