The view is great. However, if you are a disabled elderly, I would say better not go, because there is no wheelchair to lend, and there are too many stair for disabled elderly.
It’s definitely worth taking the ropeway to see the area near the mountaintop.
It costs 1,500 yen, but the view is far more impressive than what you can see from below.
If you love nature and fantastic views, THIS IS FOR YOU! If you want a beautiful view without do a lot of work I would recommend taking the rail car up to the view of Mt Fugen and Mt Unzen. BUT if you don't mind a nice 1 hour 40 min hike to the top of Mt Fugen, I 110% recommend doing the hike. Bring water and good tennis shoes or hiking boots.
Visited 7 Nov 2023, a bit late for the red leaves. Small shop and ticket booth in the building. Only a short walk up from parking lot. Round trip is 1,300jpy. Operate every 12 mins. Some steep steps along the way. Up top there is more short hiking up to the shrine but not compulsory.
