Climbing to the summit of Mount Ōdake, the highest peak of the Hakkōda Mountains, is not difficult and does not require any technical skill between May and November. To reach the peak climbers start their ascent at Sukayu Onsen or the top of the Hakkōda Ropeway, both of which can be accessed by public buses or private automobiles from National Route 103 and National Route 394. From Sukayu Onsen, it takes about two hours to complete the ascent to the summit that is accessible by a well-marked pathway. From the top of the Hakkōda Ropeway it takes two hours to ascend to the summit and another two to descend back to the aerial lift. The summit can be reached outside of the mentioned climbing season; however dangers imposed by avalanches and harsh weather make advance training, personal radio beacons, and preparation necessary.
