Don't rush to buy tickets after getting off at Asu Station, just wait for the bus at the bus stop, because there are buses, and the bus can also buy tickets when it arrives and gets off. The bus rides up the mountain with picturesque scenery. Because of the volcano eruption, the climbing ropeway stopped, and the smoke from the crater slowly flowed in the distance. It was beautiful, but the air smelled of sulphur, so I didn't stay long.
