It's worth going. It's great to go to the volcano by bus after arriving at a lovely railway station on a distinctive Asu Boy's train. It's a beautiful journey, passing through the grass thousands of miles and the volcano museum, and looking out at the snow-white smoke coming from the volcano outside the window. This is the only active volcano open to the outside world. Unfortunately, due to smoke, the cable car was out of service and failed to reach the crater. Next time you have a chance, you must go again.
