Built in 1923, it has stood through harsh winters and other extreme conditions. Though it is easy to hike and relatively close to Iceland's famous Route 1, it is still not well known among tourists. Be sure to bring your own towel for this adventure. Follow @mborowick for more pictures like this. #iceland #swimmingpool #adventure #hotspring #explore」7月23日 17時08分
