Yudanaka and Shibu are different arrivals
Yudanaka Station, hotel areas and Shibu Onsen require different routes. Set the exact accommodation and ask whether you can drive to the entrance.
Park before exploring on foot
Shibu Onsen is best explored on foot after leaving the car at your accommodation or a designated car park. Do not block narrow streets while unloading.
Treat Shiga Kogen as a separate drive
The climb from Yudanaka to Shiga Kogen has different altitude and winter conditions. Check highland road information separately if continuing uphill.
