I visited in June, but I believe the best season to visit is year-round. In the summer, you can enjoy swimming in the lake, while in winter, the contrast of diving into the chilly water and warming up in the hot onsen afterward is unforgettable. The highlight of this experience is the ability to take a refreshing dip in the lake and then head to the hotel’s onsen to relax and clean up.
