Blue Lagoon or Sky Lagoon?

Two thermal lagoons sit within reach of Reykjavik, and the wrong pick costs a trip most of a day. Sky Lagoon is close, small children are turned away at the door, and the Blue Lagoon is further out and needs a booked time slot before anyone can enter. The choice comes down to three things: how much of the trip a family can spend driving, whether children under 12 are travelling, and how the schedule sits against the airport. Sky Lagoon sits 7.5 km (4.7 mi) from central Reykjavik, a 13-minute drive. The Blue Lagoon sits 49.2 km (30.6 mi) out, a 50-minute drive, and closer to Keflavik International Airport than to the city. Neither lagoon can be walked into without a plan: one takes no reservation risk if a party is small enough for a walk-in, the other takes none at all.

Distance and drive time

A rental car or a taxi makes the distance manageable either way, but the two lagoons are not close to each other or to the same things. Sky Lagoon is 7.5 km (4.7 mi) from central Reykjavik, a 13-minute drive, and a round trip with no stops runs about 26 minutes. It is also walkable in principle at about 6 km (3.7 mi) from Hlemmur square, though that is closer to a 90-minute walk than an afternoon errand; a bus route runs from Hlemmur to Hamraborg and on to Bakkabraut, followed by a short walk.

The Blue Lagoon sits 49.2 km (30.6 mi) from Reykjavik, a 50-minute drive, and a round trip before any stop runs about 1 hour 40 minutes. From Keflavik International Airport it is much closer: 21 km (13 mi), a 15-minute drive, with Grindavik itself just 6 km (3.7 mi) further on. That geography makes the Blue Lagoon a natural stop on the way to or from a flight, and it publishes free parking and a luggage-storage building by the car park for exactly that reason. A traveller basing a whole trip in Reykjavik and never going near the airport again adds a full return drive to reach it; a traveller landing at or departing from Keflavik adds almost nothing.

Sky Lagoon does not publish luggage storage or an airport-focused pitch in the same way. Its position close to the city, not the airport, is the point: it fits into an evening after a day of sightseeing without a long drive either way.

Who can get in

This is the decision that overrides the other two for families. Sky Lagoon admits nobody under 12, without exception stated on its own site, and guests aged 12 to 14 need an adult guardian with them. Staff may ask for ID or a passport to confirm a young guest's age and can refuse entry without it. A family travelling with a child younger than 12 has no version of Sky Lagoon available to them, whatever the rest of the trip looks like.

The Blue Lagoon allows children from age 2, with a lower admission price of 2,000 ISK for guests 11 and younger. Children under 2 are not permitted in the water at all, and one adult guardian may supervise a maximum of two children aged 2 to 13 unless that guardian is the child's own parent. Free flotation armbands are provided for children up to age 8, though the Blue Lagoon is explicit that they are not a lifesaving device and continuous adult supervision still applies.

A reader travelling without children under 12 has both lagoons genuinely open to them, and the choice folds back into distance, budget and the ritual each one offers. A reader travelling with a younger child has only one lagoon to book, and no combination of price or convenience changes that.

Price and what it buys

The Blue Lagoon's cheapest package, Comfort, starts from 11,990 ISK and includes lagoon entry, unlimited steam bath, sauna and cold lagoon access, one silica mud mask, a towel, and shampoo, conditioner and moisturiser at the shower stations, plus a private locker. Premium starts from 14,990 ISK and adds a drink of choice, two extra masks and bathrobe use. Signature starts from 18,490 ISK and adds two drinks, two masks of choice and take-home skincare. A group floating activity is a separate add-on from 5,900 ISK per person, booked apart from admission.

Sky Lagoon's Saman pass starts from 14,990 ISK and covers admission, the seven-step Skjol Ritual, unlimited lagoon and cold-plunge access, a wristband used as a locker key and payment card, public changing facilities and shower cubicles. The Ser pass starts from 17,990 ISK and adds private changing facilities, a private vanity area with a blow dryer, and a reusable waterproof bag. A multi-pass exists for repeat visits: six Saman visits from 50,970 ISK, six Ser visits from 59,970 ISK, both valid for four years and tied to one named visitor.

Both operators include a towel free of charge in every package. Both charge nothing for parking. Neither publishes a total that includes food, and neither's ticket price includes transport from Reykjavik or the airport.

Volcanic activity and closures

This is the one variable that neither lagoon controls. The current unrest on the Reykjanes peninsula began on 25 October 2023, and the Icelandic Meteorological Office reported no active eruption as of its August 2026 bulletin, with about 29.1 million cubic metres of magma accumulated beneath Svartsengi and a hazard assessment valid only until 30 September 2026. The Blue Lagoon sits directly in this zone and has closed twice since the unrest began: from 8 to 16 February 2024, when an eruption near the site prompted an evacuation of roughly 150 guests, and again from 20 November to 6 December 2024, when lava reached the car park and access road before being stopped by protective barriers. Purpose-built barriers now shield the Blue Lagoon and the surrounding Svartsengi infrastructure, and walking on them is prohibited.

Sky Lagoon sits well outside this zone, in Kopavogur south of Reykjavik, and no closure is stated for it over the same period. That difference does not make either lagoon unsafe to book. It does mean a Blue Lagoon booking carries a small chance of a last-minute closure that a Sky Lagoon booking has not carried so far, and a traveller with a tight schedule around a flight should weigh that against the Blue Lagoon's convenience for exactly that same flight.

Fitting it around a flight

A lagoon visit works differently depending on which one it is and when the flight lands. The Blue Lagoon's position 21 km (13 mi) and a 15-minute drive from Keflavik International Airport makes it a genuine stop between the airport and the city, with free parking and luggage storage built for that use. A traveller with a late arrival or an early departure can route through it without adding much beyond the visit itself, provided a timed slot has already been booked, since there is no walk-in option.

Sky Lagoon does not sit on that route. It is a 45-minute drive from Keflavik, further from the airport than from the city, so a traveller trying to combine it with a flight is adding a deliberate detour rather than following a road already being driven. It suits a trip where the visit is planned as its own evening in Reykjavik rather than as a stop on the way somewhere else.

Either way, the ticket itself does not include the drive. A transfer needs to be arranged separately, whether that is a rental car, a taxi or a scheduled bus, and the lagoon admission is a distinct booking from any of them.

Common questions

Can a family with a 10-year-old visit both lagoons on the same trip?

Only the Blue Lagoon, since Sky Lagoon admits nobody under 12. The Blue Lagoon allows children from age 2, with admission from 2,000 ISK for guests 11 and younger.

Does either lagoon allow walk-ins without a booking?

The Blue Lagoon requires pre-booked, timed entry with no walk-in option. Sky Lagoon recommends advance booking but publishes separate terms for walk-in guests, implying walk-ins are possible subject to availability.

Is the Blue Lagoon currently open?

Yes. It sits behind purpose-built lava barriers and has closed twice since the current Reykjanes unrest began in October 2023, most recently for about two weeks in November and December 2024.

Which lagoon is closer to a hotel in central Reykjavik?

Sky Lagoon, at 7.5 km (4.7 mi) and a 13-minute drive, against the Blue Lagoon's 49.2 km (30.6 mi) and 50-minute drive.
