Open-air hot spring ceiling & watching the aurora in the hot spring in Iceland

Most of the hot springs in Iceland are outdoor geothermal water. When it snows, take a hot spring bath, with the upper body cool and the lower body immersed in the warm hot spring, admiring the dazzling sunset or the colorful aurora, holding a glass of red wine, it is indescribably comfortable and cozy. Drive from Reykjavik to Vik, there is a place called Seljavellir. Enter road 242 from the ring road, input Seljavallalaug in the GPS and go in for 20 minutes, then drive into the small road leading to the swimming pool parking lot, park at the end of the road, and then walk along the road sign for 15-20 minutes to find this wild hot spring Seliavallalaug hidden in the mountains. Walk into the dilapidated dressing room and be instantly brought into the Iceland of the 20s. The hot spring is natural geothermal water with a temperature of 20-30 degrees. It is recommended to enjoy the scenery, take pictures and pose. Little secret: Because it is located in a natural scenic area, the surroundings of the hot spring basically maintain the original natural landscape, and there are few human traces. There is only one road between the two waterfalls that can lead to this hot spring.
