The pool. Covered pool with a slide and a jacuzzi at about 30 °C year-round; women's pool at 30 °C; covered children's pool at 36 °C; open-air thermal pool at 41 °C; heated outdoor pool; separate thermal pools for men and women.
The hot tub. Jacuzzi in the covered pool and in the women's pool.
I haven't yet found guest reviews that mention the water temperature.
Guide's tip. The heated outdoor pool goes from 26–27 °C in summer to 34 °C the rest of the year: choose your pool according to the season.
