If you have climbed mountains of the Japanese Alps or tall volcanoes like mount Fuji, you know how good it feels to bath in a hot spring after a hard day of hiking. Now imagine you arrive at your campsite with a natural outdoor onsen waiting for you with an amazing scenery. This is the dream waiting for you at Hakubayari Onsen, the highest onsen in Japan.
A mountain hut is built every spring next to the hot spring and disassembled in fall before avalanche season. A tentsite with limited space is also located next to the hot spring (all spaces were filled by noon on the day of our hike). A small cafeteria serves a simple dinner in the evening and staff can prepare cup noodles at lunchtime. More importantly, they sell beer. Yes, Japanese mountain climbing usually involves beer and most guest of Hakubayari onsen can be seen with a beer in hand at some time during their stay.
The hut is actually on the way to Hakuba-Yarigatake, a prominent peak in the region. We started our climb of Yarigatake from the hut at around 6 in the morning and summited at around 10:30. The view was spectacular. We could see mount Shirouma, Mount Tateyama, mount Kashima-Yarigatake, and Kurobe Damm.
The trail we took back and forth to the summit starts from the Sarukura parking lot. We got a ride from familly member but I know that taxis will drive you up there from Hakuba station.
