Choose the Blue Lagoon if you want the iconic milky-blue water, the silica mud mask and the famous “Iceland” photo. It's close to Keflavík Airport, so it's perfect on your arrival or departure day.
Choose Sky Lagoon if you're staying in Reykjavík, want ocean views and a relaxing 7-step spa ritual, and prefer a slightly lower price and a shorter trip.
Traveling with kids under 12? Choose the Blue Lagoon. Sky Lagoon doesn't allow children under 12.

The Blue Lagoon: the famous one
The Blue Lagoon is Iceland's most famous attraction, a huge lagoon of warm, milky-blue water set in a black lava field.
Why go:
- the iconic look and photos,
- silica mud mask included in most packages,
- swim-up bar with a drink included in most packages,
- the perfect stop between the airport and Reykjavík, since luggage storage is available.
Downsides:
- the most expensive of the big lagoons,
- busier, especially in the middle of the day,
- 45–50 minutes from Reykjavík.
Volcano note: the Blue Lagoon is on the Reykjanes Peninsula, where there have been several volcanic eruptions since 2023. It has closed temporarily during some eruptions and reopened afterwards. Check the official Blue Lagoon website for its current status before your visit.
Booking: advance booking with a timed entry is required. Book early for evenings and holidays.
Sky Lagoon: the local favourite near Reykjavík
Sky Lagoon opened in 2021 in Kópavogur, just outside central Reykjavík. Its long infinity edge looks straight out over the North Atlantic.
Why go:
- ocean-view infinity pool, stunning at sunset and in winter darkness,
- the 7-step Skjól ritual: warm lagoon, cold plunge, sauna with a sea view, cold mist, body scrub, steam room and shower. It takes about 45–75 minutes, at your own pace,
- close to Reykjavík: easy by taxi, car or city bus,
- usually a bit cheaper than the Blue Lagoon.
Downsides:
- not the iconic blue water,
- no children under 12,
- smaller, and can feel busy at peak times.
Which one is better?
There's no single winner. It depends on your trip:
- First time in Iceland and want the classic experience: Blue Lagoon.
- Arriving or departing via Keflavík: Blue Lagoon (on the way).
- Staying in Reykjavík with limited time: Sky Lagoon.
- Want a real spa ritual and ocean views: Sky Lagoon.
- Traveling with young kids: Blue Lagoon.
- Budget-conscious: Sky Lagoon, or a local swimming pool (see below).
My honest local take: both are beautiful, and both are expensive by Icelandic standards. If you only do one, pick the one that fits your route. Don't drive an extra 1.5 hours just to tick one off.
Cheaper alternatives locals love
Icelanders go to the local swimming pool, not the big lagoons. Almost every town has one with hot tubs, and entry is usually only around 1,000–1,800 ISK.
- Local swimming pools: the real Icelandic experience. See our Swimming Pools Map and our pool etiquette guide. Showering without a swimsuit before you get in is mandatory.
- Secret Lagoon (Flúðir): a natural hot pool on the Golden Circle.
- Laugarvatn Fontana: a geothermal spa by a lake on the Golden Circle.
- Forest Lagoon (Akureyri): a beautiful lagoon in the north.
- Mývatn Nature Baths: often called “the Blue Lagoon of the North.”
- Natural hot springs: free or cheap. Find them on our Hot Springs Map.

Tips for visiting any Icelandic lagoon
- Book ahead. Walk-ins are often not possible.
- Go at sunset or after dark in winter. Steam, snow and maybe northern lights overhead.
- Protect your hair. Geothermal and silica water can make hair stiff. Use the conditioner provided and keep your hair out of the water if you can.
- Take off silver jewelry. Geothermal water can tarnish it.
- Drink water. It's easy to get dehydrated in hot water.
- Shower without a swimsuit first. It's a strict rule in Iceland.
