You can choose to soak only your feet or your whole body in wooden bathtubs, some of which have a nice setting with a view of the pond in which the water is heated. They advise you to dive in for 5 minutes, get out of the water, drink water (bottle provided), dive back for 5 minutes and so on... On the phases in the bathtub, you have to not move because the movements cause the water to stir and make the sensation of heat stronger. I did not have too many difficulties to get inside the water but it was more complicated for my wife. So maybe not a place that relaxing for people that can not dive themselves in very hot water. It is accompanied by a small do-it-yourself salt and turmeric facial treatment. They also sell a whole range of beauty products. While there, go see the salt fields just behind the spa (access on the left of the store) and the warehouse.
