The Kazurabashi Bridge in Iya Valley is a cool vine bridge that used to be the main way for folks to cross the river back in the day. Legend has it that it was either built by a famous Buddhist monk or by some defeated warriors hiding out in the valley. Only three of these bridges are left, and the biggest one stretches 45 meters across the river. It's rebuilt every three years and has hidden steel cables for safety. You can only walk across it in one direction, but it's totally worth it for the thrill of looking down at the water 14 meters below!
