It can be assumed that the only way up the mountain is through either climbing it, which was what the middle school losers had to do, or swimming through a river that connects to the mountain's caves. The latter, however, is not confirmed because it was used as a route leaving the mountain by Ryoma, Kenya, and Kei when the Drunken Coach instructed them to steal sake from the main camp. The mountain is home to many wild animals, including wild eagles.
