This narrow zigzagging road is known to be the most perilous section of the ancient road linking Busan and Hanyang, the capital city (present-day Seoul). It stretches from Jinnammun Gate of Seokhyeonseong Fortress to Ojeongsan Mountain and Yeonggang River. According to Sinjeung dongguk yeoji seungnam (Augmented Survey of the Geography of Korea), Wang Geon (877-943), or King Taejo, founder of the Goryeo Dynasty, found that there was no road ahead when he reached this place while marching southward with his troops. Then, a rabbit suddenly appeared and guided them along the steep cliffs; hence the name of the road, Tocheon, or Tokkibiri. The word "biri" is local dialect for "byeoru," literally meaning "inkstone" but also a steep cliff rising by the river or the sea. This serpentine road was made along the precipitous sides of cliffs eating into the mountainous region to the east from the point where Yeonggang River flowing down from Gaeun meets Joryeongcheon Stream from the Mungyeongsaejae Pass. The road is approximately six to seven ri (one ri equals some 400 meters) long and, in most parts, just wide enough for one person to pass. From the road, breathtaking views unfold with the river below, the cliffs, and a village beyond. Along the road are taverns, a shamanic shrine, and two shrine trees, showing some intriguing aspects of ancient roadside culture.
