Kurobe Gorge Railway
Japan's most dramatic narrow-gauge railway squeezes through the sheer walls of Kurobe Gorge in open-air carriages, hugging cliffsides and crossing delicate bridges above turquoise water. The 20-kilometre route from Unazuki to Keyakidaira takes about 80 minutes each way through tunnel after tunnel and soaring viaduct after viaduct. October transforms the gorge walls into a cathedral of crimson maples and gold larches, making autumn the single most spectacular time to ride.
