Oku-Iya Niju Kazurabashi

Deep in the remote Iya Valley of western Tokushima, two suspension bridges woven from mountain vines and wooden slats span a rocky gorge. Unlike the more visited single Kazurabashi bridge at the valley entrance, these double bridges see fewer visitors and feel genuinely wild. Walking across while looking through the plank gaps at the rushing stream below is thrilling in the best way. Nearby, a hand-powered cable car called a wild monkey lets you pull yourself across the gorge. The surrounding old-growth forest and clear river reward the winding mountain drive to get here.
