Lýsuhólslaug is a natural hot pool in western Iceland on the Snaefellsnes Peninsula. It is a geothermal pool and is said to have healing properties for the body. The pool is filled with green algae, which might sound weird, but it's actually good for your skin! Plus, there are two hot tubs to soak in. It's a chill spot to relax and enjoy the benefits of nature's spa treatment.
