Cross the famously steep Myojin and Mikuni passes and the view suddenly opens onto Lake Yamanaka, with majestic Mt. Fuji rising beyond.
Highlights
- Myojin & Mikuni Pass: A legendary climb used in the Tokyo 2020 Olympic road race. Descending the Lake Yamanaka side reveals a sweeping panorama of Mt. Fuji.
- Lake Yamanaka Myojinyama Panoramadai: A superb viewpoint overlooking the lake and Mt. Fuji. In autumn the pampas-grass fields turn golden.
- Kagosaka Pass: At 1,104 m, this historic pass on the old Kamakura Kaido sits on the ridge linking Mt. Fuji and the western Tanzawa mountains.
Riding tips
The pass sections are steep with many curves, so ride at a comfortable pace. The high elevation around Mt. Fuji's foothills means risk of road icing in late autumn and winter, so daytime during the foliage season is best.
