After visiting Seljalandsfoss and Gljufrabui we were saturated so decided we may as well go for a morning swim in an outdoor thermal pool! In my opinion it's not quite as good as Reykjadalur but still amazing and it even has free change rooms (See photo below)! To get to the pool you have to drive 10 minutes up a gravel road with lots of pot holes and then walk 20 minutes through a valley. You cross one small river along the way.
Time Required: 1.5 hours
