Iya's best known attraction is its Kazura Bashi (vine bridge). This used to be the only way to cross the river in these parts. Another plus was that the bridge could be easily cut down to stop pursuing invaders.

There are actually several bridges throughout the valley. This is the most famous (and likewise most touristy) bridge, located in West Iya. 500 Yen entitles you to a one-way trip across the wobbly, perilous structure.
