The valley between Bukhansan Mountain and Donbongsan Mountain is called "Uidong Valley." It
earned the name "Uidong" because the two peaks of Bukhansan Mountain,
Baegundae and Insubong, look like cow's ears.
One of the trails leading
up to Bukhansan Mountain and Dobongsan Mountain also starts here.
