Hello. Hope I'm posting this in the right place... Has anyone cycled up Mt. Unzen in Nagasaki? I'm thinking of riding from Nagasaki to Kumamoto in April and trying to figure out if it's better to go round it or over it.
Not cycled it, but a quick look at Google Maps reveals a limited selection of routes, none of which actually get that close to Mt. Unzen. Rt 389 or Rt 207 are the closest, but riding the 207 requires you to take a route which makes little sense. For some quality climbing, go east on the 210, join onto the 389, head south then follow the 57 to Shimbaragaiko for your ferry.
I suggest that route as the 210 looks like a stellar, scenic road.
