Doro Gorge ("Doro-kyo" in Japanese) is a gorge
formed by Kitayama River which is a tributary of Kumano River.
Kumano River flows by Kumano
Hongu Taisha shrine and Kumano Hayatama Taisha
shrine, and flows into Pacific Ocean.
The distance from Kumano Hongu Taisha to Kumano Hayatama Taisha is about 30 km, and the junction of Kumano River and Kitayama River is at about 10 km from Kumano Hongu Taisha.
Doro-kyo is located about 20 km upstream from the junction.
The gorge named "Doro-kyo" is about 10 km from there.
Especially the downstream part about 3 km has many high cliffs, huge rocks, strange rocks and caves, so it is designated as a national natural treasure. This part is called "Dorohatcho".

The boarding point is Shiko, and is near the junction of the rivers.
