149. Yuyama no Sato Onsen, Beppu A unique onsen. Essentially a set of mixed-gender baths in the forest, reached by walking through a bamboo grove (the walk takes about 3-4 minutes at a very fast pace, or a leisurely 10 minutes while enjoying the scenery). Entry 600 yen, 100 for a disposable bathing garment, 150 for a bottle of tea. After passing through the grove, you arrive at a spot with several scattered changing rooms and various baths and tubs. The baths vary - small, temperatures mostly between warm and hot, water colors vary. Map and photos of the baths attached. The highlight is the cold plunge pools - one is a tub and the other is a waterfall. There's also an utaseyu (falling water bath). A must-visit. Also great for those looking for a mixed-gender onsen with bathing garments.
