Kurobe Gorge is surrounded by precipices. The securest way to visit there is using the tram, which was originally laid down to develop a power plant. Now a tram for sightseeing runs 20.1 km from Unazuki Onsen to Keyakidaira in 80 minutes at a slow speed. It runs through 41 tunnels and over 22 bridges, with a wide variety of scenery (outside the tunnels!). The gorge creates scenes of stunning beauty, regardless of the season. Atohiki Bridge is 60 meters high above the river; this is a place that used to scare foot travelers because of its precipitous height. You can enjoy famous places for autumn leaves and open-air hot spring baths along the riverbank. Sarutobi Gorge is a 20-minute walk from Keyakidaira Station. It is a very narrow gorge and the name “Sarutobi” indicates that a monkey can jump from one side to other side. The tram operation is from mid-April to November, but the exact date depends on snow depth. Please note that this area does not connect to Tateyama Kurobe Alpine Route.
