This activity involves riding an electric-assist mountain bike through grasslands that are normally off-limits unless special permission is obtained. You can thoroughly enjoy the various charms of Aso, such as a slalom ride from Aso Station to the top of Mt. Aso with an altitude difference of about 900 meters, or the so-called “Jabinomichi Ride” that climbs up the Ogi Valley from Uchimaki Onsen to Mt. Kita Somma, depending on your physical strength or schedule.
