Value

After considering various aspects, I’d say this hot spring deserves a rating of around 3.5 to 4, but I’ve decided to give it a solid 4.

You can drive up to the base of the mountain, but reaching the hot spring itself requires a hike. It’s well-known among mountain climbers, and not commonly visited by casual tourists. The baths are mixed-gender, with simple changing areas and rustic open-air settings, adding to the wild, untouched charm.

Soaking in a natural hot spring at 1,500 meters above sea level is a truly special experience — I highly recommend trying it at least once!
