The Oni Trail follows ancient lore and oni (demon/ogre) legends across a 100km-long trail with a variety of routes that stretches across northern Kyoto prefecture all the way to the Sea of Japan. It traverses ancient pilgrimage routes, mountain paths, forest trails, village streets, castle towns, and a UNESCO Global Geopark. Park hiking, part walking; explore slowly on foot, get to know Japan, and help the planet at the same time.
