The biggest feature of Hell Valley is that it can't be seen anywhere else, and the fog will float out of the cave. Hell Valley is different from Japan in ancient times. Now Hell Valley has built many roads. It takes about 40 to 1 hour to walk around the mountain without going up. The smell in the air is different. There are many small scenic spots on the road. They are all introduced. For example, there was a monk who used the spring water to wash people's eyes. After washing, the eyes could see. There are many Chinese people who come to Hell Valley to play. When they come, they have a group from Shanghai and a group from Taiwan.
