Gustavsvik

Gustavsvik, known primarily as a large water-park and pool complex also offers a “Relaxen” area with saunas and a wellness zone. 

The sauna rooms tend to be fairly classic: wood-panel interiors, warm amber lighting and lounge-type areas where you can chill out after the heat. It works well if you want a mix of swimming, slides (if you’re in the mood), and then a sauna + relaxation part.
