Sky Lagoon or Blue Lagoon on a Cruise Stop

Which Lagoon Works From a Cruise Call?

Sky Lagoon, for most passengers. It sits in Kópavogur on the edge of Reykjavík, roughly 20 minutes from the Skarfabakki cruise terminal, so a visit costs you about three hours of your port day including transfers.

The Blue Lagoon is 45 to 50 minutes each way from the pier, out towards Keflavík, which turns the same soak into a four and a half to five hour commitment.

On a standard 8 to 12 hour call, both are possible. The difference is what else you can fit around them, and that is where Sky Lagoon wins comfortably.

The Transfer Arithmetic

This is the whole decision, so here are the numbers.

Skarfabakki to Sky Lagoon is about 12 kilometres and 20 minutes. Round trip: 40 minutes of travel.

Skarfabakki to the Blue Lagoon is about 55 kilometres and 45 to 50 minutes. Round trip: 90 to 100 minutes of travel.

Add two to three hours at the lagoon itself, including changing, showering and the soak, plus a 30 minute buffer before all-aboard.

Sky Lagoon therefore takes roughly 3 to 3.5 hours of your day. The Blue Lagoon takes 4.5 to 5.

On an 8-hour ashore window, Sky Lagoon leaves you 4.5 hours for Reykjavík or an excursion. The Blue Lagoon leaves you 3, and most of that is unusable because it is broken up by the drive.

What Each One Is Like

They are genuinely different places rather than two versions of the same thing.

Sky Lagoon

An oceanfront geothermal lagoon on the Kársnes peninsula, opened in 2021, with a 70-metre infinity edge facing west across Faxaflói bay.

Sky Lagoon holds its water at 38 to 40°C year-round, and it looks clear rather than milky. The signature is the seven-step Skjól ritual, included with every ticket: the lagoon, a cold plunge at 5 to 8°C, a sauna at 80 to 90°C with an ocean window, a cold mist, a sea salt scrub, a steam bath and a shower.

Allow 45 minutes to an hour for the ritual if you do it properly, plus time in the lagoon itself.

Our guide to pairing Sky Lagoon with a day out covers the ritual step by step if you want to plan the hour before you arrive.

Blue Lagoon

The famous one, on the Reykjanes peninsula beside the Svartsengi geothermal plant, with milky blue silica-rich water drawn from 2,000 metres below the lava field.

The Blue Lagoon holds 37 to 39°C, the setting is black lava in every direction, and the site is considerably larger. The silica mud mask is included with admission.

It also sits in an area that has been in an active eruption period since 2021, with temporary closures on several occasions, so it needs checking before you commit.

The Blue Lagoon is the more distinctive water and the more expensive hour of your port day.

What Fits Around Each

The real question on a port day is what else you get to do.

With Sky Lagoon on an 8-hour window: the lagoon plus central Reykjavík, comfortably. Hallgrímskirkja, the old harbour and lunch all fit.

With Sky Lagoon on a 10 or 11-hour window: the lagoon plus a Golden Circle excursion, which is a full and genuinely good day.

With the Blue Lagoon on an 8-hour window: the lagoon and very little else.

With the Blue Lagoon on a 10 or 11-hour window: the lagoon plus a short Reykjanes loop, or the lagoon plus a rushed hour in the city.

Neither pairs well with a South Coast run, which needs 10 hours on its own.

Cost

Prices in Icelandic krónur, and admission is only part of it.

• Sky Lagoon admission: two tiers, the higher adding a private changing room, slippers and a drink
• Blue Lagoon admission: several tiers, with peak afternoon slots the priciest
• Sky Lagoon with transfers as a package: the simplest option from a cruise call
• Golden Circle and Sky Lagoon combined day, 10 hours: 30,899 ISK per person
• Golden Circle and Blue Lagoon combined day, 10 hours: 35,099 ISK per person

Both lagoons run timed entry and both sell out, particularly between 2pm and 6pm in summer when several ships are in port.

Book the slot before you book anything else on your port day. Everything else on the itinerary is flexible and the lagoon slot is not.

Booking and Timing

Three practical rules for a cruise passenger.

Book a slot that ends at least three hours before all-aboard. That covers the transfer plus a genuine buffer, and it is the single most important number in the plan.

Take a mid-morning or early afternoon slot rather than a late one. Late slots are the ones that leave no margin if the ship's schedule shifts.

Book with transfers included where possible. A package that collects at the terminal removes the taxi negotiation and gives someone else responsibility for the timing.

The Rules Nobody Warns You About

Both lagoons work the same way and both surprise first-time visitors.

Everyone showers without a swimsuit before entering. This is standard at every Icelandic pool and attendants do check.

Bring a swimsuit or rent one. Buying at the shop is an expensive fix.

Take off silver jewellery, since geothermal water tarnishes it quickly.

At the Blue Lagoon specifically, use the conditioner in the showers before entering. The silica dries hair badly and it will feel like straw for a day otherwise. Sky Lagoon's water is not silica-heavy, so this matters less there.

Towels are included with admission at both, so there is no need to carry a wet one back to the ship.

Both lagoons hold 37 to 40°C year-round, so the season changes the air rather than the water.

When the Blue Lagoon Is Worth It

Four situations where the extra travel time is justified.

You have an 11-hour call or longer. The buffer is generous enough that the transfer stops mattering.

You are flying home rather than sailing on. Some passengers disembark in Reykjavík, and the Blue Lagoon sits 23 kilometres from Keflavík Airport, which makes it the natural last stop.

It is the specific thing you came for. The milky blue water against black lava is genuinely distinctive and it photographs unlike anything else in Iceland.

You have already been to Sky Lagoon on a previous call.

Outside those cases, the arithmetic favours staying close to the pier.

The Volcano Question

One current factor that only applies to one of them.

The Reykjanes peninsula has been in an active eruption period since 2021, with repeated eruptions near Grindavík and the Svartsengi area beside the Blue Lagoon. The site has closed temporarily on several occasions and reopened once authorities cleared the area.

Check before your call and again on the morning. The Icelandic Met Office publishes eruption updates and gas pollution forecasts for the peninsula.

Operators watch the same sources and will move you to an alternative rather than drive into a closure.

For travel alerts rather than science, SafeTravel carries the official closure notices for the whole country.

Sky Lagoon sits well away from that activity, which makes it the more reliable booking in an uncertain week.

If your Blue Lagoon slot is cancelled at short notice, Sky Lagoon is the obvious fallback and it is 20 minutes from the pier.

A Third Option: The Secret Lagoon

Worth knowing if your call includes a Golden Circle excursion.

The Secret Lagoon at Flúðir is Iceland's oldest swimming pool, built in 1891, with hot springs still bubbling along its edge. It sits directly on the Golden Circle route.

That means it costs you almost no extra travel time if you are already doing the loop, unlike either of the Reykjavík-area lagoons.

It is rustic rather than designed, with none of the ritual or the infinity edge. Some people prefer exactly that.

The Verdict

For a standard 8 to 10 hour Reykjavík call, book Sky Lagoon. It is 20 minutes from the pier, it costs you three hours rather than five, and it leaves the rest of your day intact.

For a long call or a disembarkation day, the Blue Lagoon is worth the drive, provided you book a slot with a real buffer and check the eruption status first.

For a call that already includes the Golden Circle, look at the Secret Lagoon instead and save yourself two transfers.

Book the Lagoon Around Your Call

The lagoon slot is the one fixed point in a port day, so it is worth booking before anything else and building the rest around it. Our Golden Circle and Sky Lagoon combined day covers the three main sites and includes lagoon admission with the seven-step ritual over about 10 hours, which suits a long call well. Send us your ship and all-aboard time and we will tell you honestly whether it fits.
