Mount Karita is a nice and easy hike (about one-and-half hour climb up) with a rewarding view of the valley surrounding the city of Obuse. The mountain got its name because it looks like a bird (Kari) spreading its wings. The trailhead starts at Gansho-in temple and the hike is not so steep. The trail eventually goes through the ruins of an old castle located on the mountain. I also recommend walking in the region surrounding the trailhead parking since the fields at the base of the mountain are really picturesque.
