Temperature is unexpected
As to me, hot spring is much or a bit hotter than shower water, I won’t expect the heat in the water where there’s no volcano. At least, it will be like a bath tub temperature. Because I’ve seen so much video of the steam coming out from the thermal.
Unexpectedly, I went there in the summer, June, and at noon. Feels a bit different, much more cooler than I expected.
Unlike other thermal baths around the world, the temperature here is only mild warm, staying 22-28 degrees throughout the year. So if you go in the hot summer, the water is quite chilli, but if you go in the winter, the water might have better looking, and you might feel warmer under the water.
