ゆふいん森のホテル シャン・ジュエル

Shan-Jewel's onsen is split into three separate open-air baths that guests reserve for private use rather than share with other guests. Several reviewers mention how well that suits families, letting kids splash around without worrying about anyone else in the bath. The water comes across as clear and pleasant rather than flashy. The hotel sits on a quiet, wooded plot inside Yufuin's national park, close enough to walk to Kinrinko Lake and Yunotsubo Kaido, though you would not guess it once you are past the gate. The hotel's name is built around the idea of opening a jewel box, and that carries through to guest rooms each styled around a different gem. Reviewers repeatedly single out the proprietress for how warm and attentive she is, which seems to be as much a part of a stay here as the baths.
