The Blue Lagoon Iceland

Blue Lagoon Iceland: The Honest Version

The Blue Lagoon is not a natural hot spring. It is a geothermal spa built in 1976 as a byproduct of the Svartsengi geothermal power plant on the Reykjanes Peninsula. Workers at the plant discovered the warm mineral-rich effluent pooling on the lava field and started bathing in it. The spa grew from that. The milky blue colour comes from silica particles suspended in the water. The temperature is a consistent 37-39°C.

None of this is a criticism. The Blue Lagoon is a genuinely pleasant experience and the setting - silica-white lava fields, steam rising, the architecture of the facilities recently updated after a major renovation - is striking. But visitors who expect pristine untouched nature should know what they are getting.

Booking and visiting

The Blue Lagoon requires advance booking. Slots are timed and sell out weeks ahead for popular periods (June-August, December-January). Entry starts at ISK 9,990 for adults (Comfort package, the most commonly purchased tier, 2024 pricing - roughly EUR 70). The premium Retreat package with spa treatments and restaurant access runs to ISK 20,000+.

Each package includes use of the facilities for a set period (typically 3-4 hours), a silica mud mask, a towel, and a complimentary drink at the in-water bar. The Premium tier adds an algae mask. Do not skip the silica mask; it is the best bit.

The facility is 50 minutes from Reykjavik by road and 20 minutes from Keflavik Airport. Direct buses run from both (ISK 2,500-4,000 per person). Many visitors stop at the lagoon on arrival before reaching Reykjavik, which avoids an extra drive and makes the early-morning slots (08:00) genuinely uncrowded.

What the experience is actually like

You spend most of it in warm water, moving between sections, applying the silica paste to your face, standing near a waterfall that falls into the pool, and getting drinks from the floating bar. In winter, steam rises continuously and the contrast between the warm water and cold air above your shoulders is pleasant. In summer the steam is less dramatic but the light from Iceland’s endless evenings is better for photography.

The Lava Restaurant within the complex (book separately; it fills up) is expensive and competent - the lamb dishes and the skyr-based desserts are decent. The LAVA bar inside the water serves prosecco and non-alcoholic options by the glass.

Is it worth it?

At ISK 9,990 for three hours in warm water, it is objectively expensive for what it is. Iceland is an expensive country and the Blue Lagoon is its most famous attraction. Whether the experience justifies the price depends entirely on how much you enjoy sitting in warm water - the facility is excellent, but there is no hiking, no culture, and minimal wildlife.

If the price is a significant concern, the Mývatn Nature Baths in northern Iceland offer a similar experience (geothermal water, milky blue colour, silica) at roughly half the price and with almost no queue. The drive to Mývatn is longer but Mývatn itself is surrounded by lava formations, bird life, and volcanic features that give more context to the landscape.

Wear a T-shirt in the water if your skin burns easily; the silica content is mildly abrasive over several hours.
