One of my favourite swimming pools! The first time I went here, I had no idea what I could expect, but this little pool in the middle of nowhere is a nice place to relax and just soak in warm water.
Just don't forget to shower naked before entering the pool. Icelanders are pretty intense about that. They don't put a lot of chlorine in the pool water in Iceland, so they expect everyone to clean themselves properly before entering the pool, so he pools will stay clean as well.
