Walk the 750-meter Kiyotsu Gorge Tunnel to the Mirror of Water, where one of Japan's three great gorges reflects in a still pool — a half-day from Yuzawa. Along the way, three observation points open onto the V-shaped valley the Kiyotsu River has cut through towering cliffs of columnar rock, with an exhibition corner tracing the gorge through its seasons: soft spring green, cool summer water, blazing autumn leaves and a winter like an ink painting. The shuttle bus makes it effortless: meeting at the Snow Country Tourism office beside Echigo-Yuzawa Station, it links the station with the gorge and its fantastical space of light and sound — the easiest way to reach a place no train serves.
