Getting here: Take Chou bus from Sapporo to Bikuni (美国）(about 1 hour 30 minutes). Tickets can be purchased from the vending machine at the Sapporo bus station.
The Chou bus takes you all the way to Bikuni without having to transfer buses en route, and the short hiking trail up to the Ogon Cape is a 5 – 10 walk from the Bikuni bus station. The trail up to the wooden two story viewing platform is about 400m. The view on the way up is unremarkable until you catch a glimpse of the sea. From then on, the combination of fresh air, crystal-like water, and mountains is just stunning.
The beautiful view and overwhelming sense of calmness makes the detour to the Ogon Cape worth the trouble of getting up early and enduring the long bus ride there.
