Iceland's Pool Culture Isn't a Wellness Trend. It's an 1000-Year-Old Habit With A Survival Story to Tell
Icelanders have been bathing in geothermal water for over a thousand years. When UNESCO recognized the tradition in December 2025, it wasn't the tourist lagoons that made the list. I visited all three tiers, an 800-year-old ruin, an everyday public pool, and a luxury lagoon, to see the difference.
Icelanders have been soaking in geothermal water since before the country had a written language. It's deeply part of their culture. In fact, if you're planning trip there and you do any research, you'll find out this fact immediately. And to confirm how integral this is to the Icelandic culture, UNESCO added Icelandic bathing culture to its list of the world's Intangible Cultural Heritage in December 2025 . That is the same list that includes the French baguette and Finnish sauna tradition.
So when you go to visit, here's the detail most of the coverage of that announcement left out: the pools that actually got recognized aren't the ones most visitors ever see. Blue Lagoon and Sky Lagoon , the two names most international travelers associate with Icelandic bathing, aren't really what the recognition is about. These experiences are new. The honor is to recognize Iceland's community-run public pools . I visited three different tiers of this tradition, a 10th-century ruin, the country's oldest public pool, and a luxury lagoon, to see what actually separates them.
Why This Started as Survival, Not Relaxation
The nomination, prepared by Iceland's National Museum with input from swimmers and communities nationwide, was built specifically around public pools as shared civic space, places where, per UNESCO's own language, people of all ages and backgrounds swim, socialize, and unwind side by side, often for the equivalent of a few dollars. The reason Iceland has this many pools at all traces back to drowning, not wellness. In the early 20th century, Icelandic fishermen were dying at sea in large numbers, and few of them could swim. The government's response was to make a law in 1940 making swimming lessons mandatory for schoolchildren nationwide. A law that, with updates, is still in effect today. The pools that got built to teach those lessons, heated by the same geothermal water that warms Icelandic homes, are the same pools that later became the country's social centers, its version of a town square.

(Dream Network Media)Stop One: The Pool That Predates All of This
Snorralaug in Reykholt is a 13th-century stone hot spring linked to saga writer Snorri Sturluson.
Before there was a public pool system to recognize, there was already a much older bathing tradition in Iceland, and Snorralaug is where you can still see it. Located in the small village of Reykholt, this stone-lined pool is believed to date to the 10th century, inherited, not built, by Snorri Sturluson, the medieval Icelandic chieftain and writer largely responsible for preserving Norse mythology in written form. Sturluson lived at Reykholt starting in 1206, and an underground passage once carried heat from the pool into his farmhouse. Bathing here has been banned since 1817 to protect the site, so it exists now purely as a piece of history, older than the modern pool tradition, and outside the UNESCO inscription entirely, but still the clearest physical evidence of how long this country has been doing some version of this.
Stop Two: The Kind of Pool UNESCO Honored
Sundhöll Reykjavíkur , the unassuming public pool. It's Reykjavik's first public swimming pool.
Sundhöll Reykjavíkur , Reykjavik's oldest public pool, opened in 1937 in the city center, designed by the same architect behind the Hallgrímskirkja church that anchors the capital's skyline. This is the plain pool the UNESCO inscription is actually describing. I got to witness the legacy of this swimming culture play out in real time. A busload of schoolchildren pulled up while I was there, dropped off for the same kind of swim lesson this whole tradition was built around in the first place. Entry costs $9. And inside (no photos allowed) it was the most unpretentious, normal day-in-the-life expereince to witness. Nobody was there to be seen. It was simple, a little worn in, loud with kids, and completely unglamorous in the way a neighborhood pool typically are. That's the entire point of what UNESCO recognized: not a destination, just a place locals show up and use at their thrid space.
Stop Three: The Reason for My Visit
Journalist Dayvee Sutton at Sky Lagoon
(Dream Network Media)I was invited by Sky Lagoonto experience their grounds before general admission hours, and the setting alone was one of the most magical I've ever had. The lagoon sits cut into a cliffside over the North Atlantic, and the infinity edge blurs into the horizon so completely that it stops feeling like Iceland and starts feeling like somewhere that shouldn't exist. I had time to sit in the lagoon itself, before the other guests. (Just our small group of six journalists.) We had about an hour to ourselves, and then started the seven-step Skjól ritual: a soak in the geothermal water, a cold plunge, a sauna facing the ocean, a cold mist chamber, a sea salt scrub, a steam bath, and a final shower. It is, unmistakably, a spa experience, and that's by design. But Icelandic tradition is threaded through every step rather than bolted onto a generic wellness format. The turf-walled sauna is a direct homage to the turf houses early Icelanders lived in for warmth. Ása Valdimarsdóttir, Marketing and Brand Experience Coordinator for Sky Lagoon explained "This style of house is using the turf, which is an old Icelandic method dating back to 870... this is the turf house at Sky Lagoon, built to honor the ones early Icelanders lived in, and designed to have the water heat the buildings here." And the ritual's cold plunge was modeled directly on Snorralaug, tying the newest stop on this list back to the oldest one.
What matters most, though, is that this isn't a tourist-only performance of Icelandic culture. Locals genuinely treat Sky Lagoon as part of their own bathing tradition, not a separate thing built for visitors. It's become a go-to gift for teenage birthdays and a place Icelanders bring themselves for a treat on a special occasion, the same instinct that sends a family to their neighborhood pool, just dressed up for a milestone instead. Packages run well over $100 depending on the tier, and the ritual area was expanded again in 2024 to keep up with demand from locals and visitors alike.
