Discover the Maa Sauna, an authentic and original Finnish experience, also known as the ancient sauna or earth sauna (Maa is the Finnish word for 'earth').
The Maa Sauna was originally built partially underground, hence its name. We decided to keep with tradition at Thermen Soesterberg. Our sauna is partially underground, which creates a cosy feeling. Having been partially carved into the earth, this sauna maintains its wood-fired heat naturally. The Finnish Kelo wood used to build the sauna further enhances this effect. This creates the perfect climate and sauna experience. Despite temperatures of up to 110 °C, the dry heat feels pleasant and mild. Experience the healing power and health benefits of an authentic sauna!
