We drive along the south coast towards the east, passing black lava sands and unearthly landscapes, until all of a sudden, you take a left to Raufarfell, passing by farms and sheep and continuing into a narrow valley belowing to the infamous EyjafjallajÃ¶kull (when the E-volcano errupted, this valley was completely covered in ashes). Then we park our car, walk for 15 minutes following a babbling river, upstream, and we end up at one of the most charming outdoor swimming pools in Europe, built in the 1920 to learn Icelanders how to swim. The water at the seljavallalaug swimming pool is toasty warm with a big thank you to geothermal energy.
So even in winter, when the scenery is all white, you can still bathe here, or even learn to swim. In summer you can find a couple of people splashing around but off season you will probably be the only living soul. Why not swim as a real Viking and go skinny-dipping, such a very cool thing to do. Cool in many ways!
