lonely planet reports: For a long time, the Blue Lagoon dominated the high-end bathing market in Iceland. The milky blue geothermal seawater in the middle of a lava field is still perfect for jetlag recovery (it helps that it's 20 minutes from the airport). More geothermal baths and spas have popped up in recent years, attracting visitors for their elegant architecture, stunning settings, and unique bathing experiences. The Mývatn Nature Baths in northern Iceland overlook Lake Mývatn and the surrounding bird-filled wetlands and volcanic landscapes. Situated on the banks of Lake Laugarvatn, Laugarvatn Fontana pipes in natural steam for its steam bath.
If you're looking for solitude, the Canyon Baths by Húsafell include a guided hike through stunning Icelandic wilderness followed by a dip in the secluded geothermal pools. For Insta-worthy views, Geosea in Húsavík overlooks Skjálfandi Bay and its snow-tipped mountains. Vök Baths near Egilsstaðir features geothermal pools floating in Urriðavatn Lake. Right on the capital's doorstep, Sky Lagoon in Kópavogur brings a fully Icelandic spa experience within reach for visitors to Reykjavík. New "forest baths" are due to open in early 2022 outside Akureyri.
