Seljavallalaug is an old man-made geothermal pool about 2 hours south of Reykjavik that is maintained by local volunteers from the surronding farm country, the pool was a little grimy but if you can get over that than the scenery and setting of the place can truly send you to another world.
Before getting in the pool I noticed an old faded bitcoin sticker slapped on a metal pole, always nice to see Bitcoin being promoted where you least expect it.
If you ever have a chance to come to Iceland do yourself a favour, rent a car and take the trek down to the South, nature here is stunning. Have a good one guys and steem on
