Secret Lagoon

Tucked into a steamy geothermal field near Flúðir, Iceland’s oldest swimming pool offers a truly authentic soak. Fed entirely by bubbling hot springs—including the Litli Geysir—the water stays a toasty 38–40°C year-round and refreshes completely every 24 hours. Simple, natural, and rich in minerals—this is true Icelandic bathing.
