Blue Lagoon vs Sky Lagoon: Which Geothermal Spa Should You Choose?

If you are weighing up the Blue Lagoon vs Sky Lagoon, the good news is that you cannot really choose wrong. Both are geothermal spas with warm water and a distinctly Icelandic setting. The better question is which one fits your plans, because they are in different places and offer different experiences.

This guide compares them on location, atmosphere, timing and transport. For the latest prices, opening hours and what is included, check each spa's own website before you book, as those details change.

Location: the biggest difference

The Blue Lagoon is on the Reykjanes peninsula, set in a lava field roughly 20 minutes from Keflavík Airport and about 50 km from central Reykjavík. Sky Lagoon is on the edge of the capital area, a short drive from the city centre, with views over the sea.

That one fact decides a lot. The Blue Lagoon fits neatly before or after a flight, since it is close to the airport. Sky Lagoon is easier to fit into a day spent in Reykjavík, when you are already in town.

Atmosphere and setting

The Blue Lagoon is known for its milky blue water and the black lava that surrounds it, with silica-rich water that gives the lagoon its colour. It feels like a landscape you are bathing in. Sky Lagoon leans on its ocean-edge setting and a design built around the horizon, so the experience feels closer to a modern spa with a sea view.

Both are popular, so they can be busy at peak times. If you want a calmer visit, ask each spa about quieter time slots and book in advance.

Which one fits your trip?

• Choose the Blue Lagoon if you are landing or leaving and want a soak next to the airport, or you want the classic lava-field setting.
• Choose Sky Lagoon if you are staying in Reykjavík for a few days and want a relaxed evening or half day without a long drive.
• Visit both if you have several days in the capital area and you enjoy spas. Many travellers choose one and spend the rest of their time on tours.

How to get there

Both can be reached without a rental car. Options include scheduled shuttles, taxis and a pre-booked private car. Check current prices and timetables for the first two, and compare them with the cost per car for a private driver if you are a group or have luggage.

For the Blue Lagoon, a private driver can take you from the airport to the lagoon and on to Reykjavík in one smooth sequence. Our fixed-price transfers are per car, not per person: Economy (Tesla) for 1 to 4 passengers and Van (Mercedes Vito) for 5 to 7, with minibus options for 8 to 16 on request. Message us on WhatsApp at +354 777 3949 with your plans and we will tell you what we can arrange.

Our guide to the Blue Lagoon on arrival or departure day covers timing and luggage in more detail, and our overview of every way from Keflavík to Reykjavík lists your options for the onward leg.

Timing your visit

The best time of day depends on what you want. Mornings and late evenings are often calmer than the middle of the day, and in winter an evening soak under a dark sky is memorable, as long as you dress warmly for the walk to the water. In summer the bright night adds a different kind of magic, with soft light long after dinner.

On a travel day, give yourself more margin than you think you need. A soak that finishes late can leave you rushing, and rushing is the opposite of what a spa day is for. If in doubt, book an earlier slot.

Practical tips for either spa

• Book your entry time in advance, especially at weekends and in high season.
• Shower before entering, as is the custom at all Icelandic pools.
• Bring a swimsuit and consider a hair conditioner, since geothermal water can dry hair.
• Keep valuables to a minimum and use the lockers provided.
• Drink water, because hot water and travel both dehydrate you.

Finally, keep winter in mind: the water is lovely in the cold, but walking between changing rooms and the lagoon is chilly. If you plan a soak after dark in the winter months, see our notes on Iceland in winter.
