Every Iceland trip eventually leads to the same question: Blue Lagoon or Sky Lagoon? We’ve done both — the Blue Lagoon on our Ring Road trip and Sky Lagoon on a Reykjavik stopover — and they’re honestly very different experiences wearing the same “geothermal lagoon” label.

This isn’t a “both are great!” non-answer. We have a clear preference, and by the end you’ll know which one fits your trip better.

The basics: what each lagoon actually is

Blue Lagoon

The Blue Lagoon sits in a lava field on the Reykjanes Peninsula, about 50 minutes from Reykjavik and 20 minutes from Keflavik Airport. It opened in 1992 and has become, arguably, Iceland’s single most recognizable attraction. The water is a milky turquoise, heated by a nearby geothermal power plant, and the setting — black lava rock, rising steam, sometimes snow on the ground — is genuinely otherworldly.

It’s big. Really big. There’s a restaurant, a hotel, a spa, and the lagoon itself can hold hundreds of people at a time. You’ll get a complimentary silica face mask and a drink included in most packages.

Sky Lagoon

Sky Lagoon opened in 2021 on the Kársnes peninsula in Kópavogur, roughly 15 minutes from downtown Reykjavik. It’s built into the coastline with an infinity-edge pool that drops visually into the North Atlantic. The design is modern Icelandic — concrete, wood, turf roofs — and the whole place feels more curated and intimate than Blue Lagoon.

The signature experience is the Skjól ritual: a 7-step circuit of warm lagoon, cold plunge, sauna, cold mist, steam room, sky body scrub, and a final shower before returning to the pool. It takes about an hour and genuinely makes your skin feel different.

Getting there: logistics that actually matter

Blue Lagoon logistics

• From Reykjavik: 50 min by car or 45 min by Reykjavik Excursions bus (runs hourly, ~€25 each way).
• Airport stopover: 20 min from Keflavik. Luggage storage available on-site. This is the classic “first or last day in Iceland” move.
• Timing: book the earliest or latest slot to avoid peak crowds. We went at 8 am in September and had a much better experience than our afternoon attempt years earlier.

Sky Lagoon logistics

• From Reykjavik: 15 min by car, taxi (~€15), or city bus route 4 + short walk.
• No airport connection: Sky Lagoon doesn’t make sense as a Keflavik layover activity.
• Timing: sunset slots are stunning if the sky cooperates. Weekday mornings are the quietest.

If you only have one day

• Flying in/out of Keflavik and want a quick soak? Blue Lagoon — it’s on the way.
• Spending a few days in Reykjavik and want a local evening out? Sky Lagoon — no contest.

What it’s actually like: honest experience comparison

Blue Lagoon: the spectacle

Walking out of the changing room into the Blue Lagoon for the first time is a genuine “wow” moment. The scale, the color, the steam drifting over black lava — you understand why it’s famous. We put on the white silica masks, floated to the swim-up bar, and felt like we were in a movie set.

The downside: it can feel like a movie set. At peak times there were so many people that finding a quiet corner required strategy. The water gets cloudy near the bar area. And the whole experience is tightly time-slotted — you feel the clock.

Sky Lagoon: the ritual

Sky Lagoon hit differently. The infinity edge looking out over the Atlantic, with no land in sight, created a stillness that Blue Lagoon’s lava field can’t match. The 7-step ritual — especially the transition from scorching sauna to the cold plunge — left us feeling genuinely reset, not just warm.

It’s smaller, so you’re not wading past dozens of people. The crowd skewed more local. The design feels intentional in a way that respects the landscape rather than competing with it.

Our honest take

Blue Lagoon is a once-in-a-lifetime photo. Sky Lagoon is a place you’d go back to. If someone told us we could only do one, we’d pick Sky Lagoon — but we’d also say you should do Blue Lagoon at least once if it’s your first time in Iceland.

Mistakes we made (so you don’t repeat them)

• Booking Blue Lagoon for a 2 pm weekend slot. Peak crowd. Our second visit at 8 am on a Tuesday was a completely different experience.
• Not bringing our own flip-flops. Both lagoons have slippery changing rooms. Bring cheap flip-flops.
• Skipping the cold plunge at Sky Lagoon. The first time, Alla skipped it. The second time she did the full circuit and said it made the whole experience twice as good.
• Underestimating Blue Lagoon’s distance from Reykjavik. We assumed 20 minutes. It’s closer to 50. Plan your day around it, not between other things.
• Not conditioning our hair. Silica and geothermal water wreck hair. Both lagoons provide conditioner — use it before you get in, generously, and leave it in.
• Trying to do both in one day. Technically possible but you’ll be rushed and waterlogged. Give each its own day.

Frequently asked questions

A final word from Rovaniemi

We live in Finnish Lapland, where geothermal pools aren’t really a thing — our version is a frozen lake with a hole cut in the ice and a wood-fired sauna on the bank. So when we get to Iceland, we appreciate these lagoons for what they are: something we genuinely can’t get at home.

Blue Lagoon gave us the photo we still have on our wall. Sky Lagoon gave us the evening we still talk about. They’re not competitors — they’re different answers to different questions. Figure out what you’re actually looking for, and the choice makes itself.
