11. Sky Lagoon, Kópavogur
Kópavogur’s headline attraction is the Sky Lagoon, which opened in 2021. The newest addition to Reykjavík’s spa scene has a traditional look, with the changing rooms and café set in moss-covered, flint-walled buildings. The lagoon itself features a main pool with an infinity pool gazing out over the sea, a tumbling waterfall, and a bar where champagne, beer and wine are on offer at prices not quite as high as you might expect.
The whole setting, carved into craggy rocks, is spectacular, although the approach sees you pass through a rather uninspiring industrial estate. Many tourists will still choose to visit the Blue Lagoon, but this is better value and just as memorable. Visiting during the gorgeous low light of sunrise or sunset is unforgettable.
12. Secret Lagoon, Flúðir
Flúðir is simply a knot of services – a bank, supermarket, accommodation and a couple of places to eat – focused around a junction on Route 30, a back road to Gullfoss. The main reason to visit is to soak in the Secret Lagoon.
The Gamla Laugin (Old Hot Pool) at Hverahólmi, is just north of town. Here thermal springs in a grassy field have been diverted into a no-frills, open-air pool the size of a village duck pond; it’s a secret no longer and is incorporated into several tours.
Constructed in 1891 but later abandoned, recent renovations have converted the old hothouses to changing rooms, retaining a crumbling building which adds an atmospheric air, particularly when wreathed in steam.
