Staying at Shima Onsen was a real delight. I would highlight the incredibly friendly and gracious staff, who made me feel very welcome and looked after as a solo traveller, and made the beautiful dining experience even better. I enjoyed walking through the lovely nearby streets and forests - it felt very secluded and tranquil. And there was nothing better than coming back from a big walk to relax into one of the onsen - either public or private, depending on what you preferred. I wish I had more time to stay, but even two nights was enough to feel very rejuvenated.
