Sky Lagoon Rules: Age Limit, What to Wear and What to Bring (2026)

Researched guide — we have not visited Sky Lagoon or booked through the links below. Built from Sky Lagoon’s own FAQ, terms and conditions and etiquette page. Part of our rulebooks.

Sky Lagoon sits on the ocean edge of Kópavogur, a few minutes from central Reykjavík, and it is strict in a few places where first-timers do not expect it: a hard age limit of 12, swimwear that has to be actual swimwear, a naked soap shower before you go in, and a cap of three alcoholic drinks. None of it is hard once you know it. Here is what the lagoon itself says, in one place, with the passes compared and what to pack.

What is the age limit at Sky Lagoon?

Twelve. Sky Lagoon’s terms say children under 12 are not permitted, and that youths aged 12 to 14 must be accompanied by a guardian who is 18 or older and who supervises them at all times. Staff will ask for a valid ID card or passport to confirm a child’s date of birth and can refuse entry if you cannot show one (Sky Lagoon terms and conditions, point 3). The FAQ adds a practical tip: families are pointed to the Sér pass, whose private changing rooms give more space and privacy (Sky Lagoon FAQ).

Travelling with younger children? Our Iceland lagoon age limits page compares Sky Lagoon with the Blue Lagoon, Secret Lagoon and the city pools, several of which do take small children, and the Iceland lagoon chooser picks the one that fits your group and route in four questions.

What do you wear at Sky Lagoon?

A swimsuit, and it has to be real swimwear. The terms are specific: swimsuits “must be made from swimwear-specific fabrics designed for water use”, and clothing made from cotton, wool, fleece or other non-swim fabrics is not allowed, because it degrades in the water and affects water quality. If you arrive without one, swimsuits can be rented or bought in the welcome area (terms, point 27). Unlike a German Therme, there is no nude area: the lagoon’s own etiquette page calls a swimsuit “obligatory for all spa goers”.

For the café and bar inside, Sky Lagoon asks guests to be fully dressed.

The shower rule (and the other house rules)

Showering with soap and without swimwear before entering the lagoon is obligatory (terms, point 28). This is standard across Iceland; our Iceland shower rules page explains why. Sky Lagoon’s two changing tiers make it easier than it sounds: Saman has shower cubicles and a shared changing area, Sér has private showers and private changing areas.

The rest of the rules from the terms and the venue’s spa etiquette page:

• Shoes off before the changing rooms; Icelanders bathe barefoot.
• Phones: phone use, photography and recording of any kind are strictly prohibited in changing rooms and showers. In the lagoon, photos for private use are allowed, but not of other guests without their consent, and no tripods, selfie sticks, flashes or cameras larger than a smartphone.
• Alcohol: a maximum of three alcoholic drinks per wristband. Staff can ask for a breathalyzer test; above 0.08% you do not go in.
• Quiet: talking is fine, at spa volume.
• No outside food or drink, no smoking or vaping, no pets, and you stay inside the guest area (not in the ocean).
• Dry off before walking back into the changing rooms.

Saman or Sér: which pass?

Both passes include lagoon entry, one journey through the Skjól ritual (the seven-step hot and cold circuit with the scrub and the Saft elixir), unlimited cold plunge, a towel and a wristband that is your locker key and payment card. The difference is the changing room (Sky Lagoon packages):

	Saman	Sér
Adult (from)	€115.75	€138.91
Youth (from)	€57.87	€69.45
Changing	Shared area, shower cubicles	Private changing and private shower
Extras	Shampoo, conditioner, shared vanity and blow dryer	Plus body lotion, private vanity, reusable waterproof bag
Best for	Most visitors	Anyone shy about the shower rule, and families with 12–14-year-olds

There are also “for two” packages with a drink and a platter, including a seasonal one sold from 28 September to 5 November, and a transfer option operated by Reykjavik Excursions. Prices change with the date and the exchange rate; these are the “from” prices shown in euro in October 2026.

What to bring to Sky Lagoon

• A swimsuit in proper swim fabric (or budget for renting one).
• An ID or passport for anyone aged 12 to 14, and for anyone who might look it.
• A credit card: it is linked to your wristband at check-in.
• Hair ties and anything you need after showering; towels, shampoo, conditioner and hairdryers are provided.
• A waterproof phone pouch only if you want photos in the lagoon; Sky Lagoon says it is not liable for water damage to cases.

You do not need a towel, a robe for the lagoon, or food. The longer list, compared with the Blue Lagoon, is in what to bring to the Blue Lagoon and Sky Lagoon.

Can you see the northern lights from Sky Lagoon?

Sometimes. Sky Lagoon itself says that if you time your visit right you may see the northern lights over the ocean, and it makes no promise beyond that (Sky Lagoon experience page). From roughly autumn to spring the sky is dark in the evening; book one of the last slots of the day, check the aurora forecast from the Icelandic Met Office that afternoon, and treat any lights as a bonus. The lagoon sits on the edge of the capital area, so city light is never far away. If seeing the aurora is the goal, a separate northern lights tour away from the city is the surer bet. Our guide to northern lights from an Iceland lagoon sets each lagoon’s last time in the water against darkness and gives the plan we would use.

Getting there and where to stay

From Keflavík Airport, Sky Lagoon recommends the Flybus to Hamraborg, then a 30-minute walk, bus 35 or 36, an e-scooter or a five-minute taxi (FAQ). From Reykjavík it is a short drive or bus ride. The lagoon recommends 1.5 to 2 hours in the water, at roughly 38–40°C and up to 120 cm deep.

Because it is this close to town, most visitors sleep in Reykjavík and add Sky Lagoon to a city day or an arrival evening. Hotels in Reykjavík on Booking.com (affiliate link) is the easiest place to compare. For a whole Iceland bath trip, pair this with the Blue Lagoon vs Sky Lagoon comparison and the Reykjavík city pools, where locals actually bathe.

FAQ

Can a 10-year-old go to Sky Lagoon?

No. Children under 12 are not permitted. Ages 12 to 14 can go with a guardian aged 18 or older, and staff may ask for ID.

Do you have to shower naked at Sky Lagoon?

Yes, a soap shower without swimwear before entering the lagoon is obligatory. The Sér pass gives you a private shower and changing room if you prefer privacy.

Can I wear shorts or a T-shirt in Sky Lagoon?

Only if they are made of swim fabric. Cotton, wool, fleece and other non-swimwear fabrics are not allowed. Swimsuits can be rented or bought on site.

Can I take my phone into Sky Lagoon?

Into the lagoon, yes, for private photos that do not include other guests without consent. Phones and cameras are strictly prohibited in the changing rooms and showers, and selfie sticks and tripods are not allowed.
