hello, how can I get to the Hell Valley from Noboribetsu? are there buses or shuttles?
This is Hazuki.
Hell Valley can access from Noboribetsu station.
First, please take a bus to Noboribetsu Onsen. ( takes 15min. 340 yen, one or two buses per hour. )
Then, please walk to Noboribetsu Park Service Center. ( takes about 10min)
I hope you can enjoy wonderful Onsen there!
