Tsuru-no-yu

The Myōban area has a number of wonderful hidden baths, tucked away out of the public eye. Locals built and maintain Tsuru-no-yu (the easiest to reach), a lovely free rotemburo up on the edge of Ogi-yama. During July and August, a natural stream emerges to form the milky blue bath. Take a bus to Konya Jigoku-mae bus stop (25 minutes northwest from JR Beppu station). Walk up the small road that hugs the right side of the graveyard until the road ends.

Dive into the bushes to your left, and there's the bath. The Beppu station information desk ladies (volunteers all!) are also happy to make you a hand-drawn map.
