Guðrúnarlaug Hot Spring, located in the west of Iceland, is a hidden gem with a fascinating history dating back to Viking times. Legend has it that a prophetess named Guðrún used to frequent this natural hot tub, where she received predictions about her four doomed marriages. After being closed for 140 years due to a landslide, the hot spring was rebuilt in 2009 and now offers a serene spot for visitors to relax and soak in the geothermal waters amidst stunning mountain views. It's a perfect off-the-beaten-path destination for those seeking a peaceful and unique hot spring experience in Iceland.
