This geothermal spa is perfect when you're covering the Golden Circle. It's a family friendly option (children 9 and under get in for free) if you want something a bit more fancy than the local swimming pools. Towels and swimsuits are available for rent.

It consists of two pools, a hot tub with a great view of the lake, steam room, sauna, and the lake. It's super nice to jump into the lake when you're getting a bit too toasty in the hot tubs. 

They also do some fun rye bread tours which show you how to bake bread the traditional way (in the ground using geothermal heat) and of course you'll get a taste of the bread when it's ready!
