Hrunalaug is a small, intimate geothermal pool tucked into rolling farmland near Flúðir. The warm water collects in a natural stone-lined basin beside a rustic turf-roofed shelter, giving the place a remarkably peaceful and timeless feel. Its size and secluded setting make it a favorite for travelers seeking a quiet soak in nature away from large commercial spas. The area is privately owned and carefully protected, so visitors are expected to treat it with respect.
Arrive early morning or late evening to avoid crowds, as the pool is small and fills quickly. Bring a towel, water, and proper footwear; the walk from the parking area can be muddy. Photography is beautiful here, but be mindful of other bathers who may want privacy. Payment is made on-site, often through a simple honesty system.
