This place is DEFINITELY worth the detour. Gio-ji is a shrine dedicated to a beautiful dancer who fell out of favour with the local lord, renounced the world and became a nun. It's set deep in the forest, filled with trees, shrubs, lush green moss covers the ground everywhere - it's magnificent to wander the paths. But it's tiny in comparison to some of the other places in Arashiyama. It's far enough removed from the main tourist attractions in town that there are fewer people here, and you can really enjoy the zen tranquility of the site. Don't forget to visit the building at the back of the gardens - there is a dedication to a big white temple cat who used to roam the gardens. Very cute.
