Sky Lagoon

The in-town soak that costs you no half-day

The pitch for Sky Lagoon is geography. It sits at the Kársnes harbour in Kópavogur, about 15 minutes south of central Reykjavík, where the Blue Lagoon is 45 minutes out on the Reykjanes peninsula. That difference matters more than it sounds: you can do Sky Lagoon as an after-dinner soak and still keep your whole day for the Golden Circle or the harbour, whereas the Blue Lagoon swallows the best part of a half-day in transfers unless you fold it into the airport run.

The headline is the 70-metre infinity edge that drops straight towards the Atlantic, so on a clear evening you’re shoulder-deep in warm water watching the sun sit on the sea (and, in winter, with a real chance of the aurora overhead if the sky cooperates). Book a timed entry online before you go — the late-afternoon and sunset slots are the first to fill, pricing is dynamic, and a quieter morning slot is usually cheaper than a Saturday evening.

Which pass, the Skjól ritual, and what it costs

There are two passes. Saman (from about ISK 13,990 / £84) gets you the lagoon, the seven-step ritual and a drink, using shared changing rooms. Sér (from about ISK 16,990 / £102) is the same experience with a private changing suite and premium toiletries. Unless you specifically want a private cubicle, Saman is plenty — both include the full ritual, which is the part people actually come for.

That ritual is Skjól (Icelandic for “shelter”): a seven-step circuit of the warm lagoon, a cold plunge, a glass-walled sauna over the sea, a cold mist, a salt body scrub, steam, and back to the lagoon. You take it at your own pace; most people do it once and it runs about 45 minutes. Allow two to three hours all in for the ritual, the lagoon and changing. Hours in 2026 run roughly 09:00–22:00, opening later on some winter weekdays and shortened on 24–25 December, with last entry about 90 minutes before close and the ritual closing earlier than the lagoon — confirm your date on skylagoon.com. The shower-before-bathing rule is mandatory and enforced.

Getting there, the volcano question, and is it worth it?

A taxi from the centre is roughly ISK 3,000–4,000 (£18–£24) each way, the operator runs a paid shuttle from central pick-up points, and there’s free parking if you have a hire car. On the volcano question that haunts the Blue Lagoon: Sky Lagoon is in the capital area, not on the eruption peninsula, so it has avoided the short-notice closures the Blue Lagoon has faced since the December 2023 eruption series began — GOV.UK still advises checking the Icelandic Met Office (vedur.is) and SafeTravel (safetravel.is), but the risk to your booking here is far lower.

If your trip is mostly Reykjavík and the day trips around it, Sky Lagoon is the better-value soak — the 15-minute hop, the ocean-edge ritual and the evening hours make it easy to slot in. The Blue Lagoon still wins if you want that famous milky-blue silica water and you’re passing Keflavík anyway. Do one, not both, unless lagoons are the whole point of the trip.
