The sour soup hot spring is quite far from Aomori City, and it takes nearly an hour to take the JR bus. The hot spring hotel has a free shuttle bus, but only runs at 2 pm. The hot spring is on the mountain, so if you go in winter, there is a lot of snow, and it is good to go skiing on the top of the mountain. The hot spring is acidic and must be washed clean after washing.
