The hot spring onsen experience might be one of the major draw cards to the area, but there's no doubt most of the visitors are there, at least partly, to ride the wonderful little railway that runs out of Unazuki Springs.
Operating from mid-April to November every year, the Kurobe Torokko Electric Railway was originally used to carry workers to the construction sites for the hydroelectric dams in the Gorge. It’s just over twenty kilometres from Unazuki to the terminus at Keyakidaira and the trip takes around eighty minutes each way.
