Mushroom Rock Road (キノコ岩街道, Kinoko Iwa Kaidō?) is notable chiefly for its mushroom-shaped rock formations and as the site of the ill-fated Operation Mi'ihen, where the Crusaders and the Al Bhed tried — and failed — to defeat Sin by using ancient machina, as seen in Final Fantasy X. It later became the base of operations and training ground for the Youth League in Final Fantasy X-2, as well as the Crimson Squad, as documented in the many Crimson Reports. The Den of Woe is located in a ravine here. The road is also the link between the Mi'ihen and Djose highroads.
