Located at the foot of Mt. Ishizuchi, the Omogo Gorge is well known as a national scenic site and delights visitors with its seasonal beauty. The water in the gorge is crystal clear and you can see to the bottom of the river even from the walking trails. There are two trails; one is the Honryu (main stream) Route including scenic beauty spots such as Goshiki-kawara, Momiji-kogen, and Toraga-taki. The other is the Teppo Route, a relaxing trail along the tranquil Teppo River. The gorge is popular with visitors seeing the autumn foliage in early November.
