Is Blue Lagoon open at Christmas?

Yes, Blue Lagoon is open every day of the Christmas holiday period, including Christmas Eve, Christmas Day, and New Year’s Eve — but with adjusted hours on some dates. The geothermal spa runs on a holiday schedule that shortens the operating window on Christmas Eve and New Year’s Eve, while Christmas Day and New Year’s Day stick to the standard winter hours.

What are the opening hours on Christmas Eve?

On Christmas Eve, December 24, the Blue Lagoon opens at 08:00 and closes at 16:00 — a full six hours shorter than the usual winter closing time of 22:00. The official Blue Lagoon opening hours page confirms this reduced schedule. Guests must exit the water 30 minutes before closure, so the last entry is around 15:30.

Is Blue Lagoon open on Christmas Day?

Yes, Christmas Day (December 25) follows the standard winter hours: 08:00 to 22:00. No special restrictions apply. The same hours apply on Boxing Day, December 26, as confirmed by Iceland.org.

What about New Year’s Eve?

New Year’s Eve, December 31, operates from 08:00 to 18:00. The shorter day allows staff to prepare for the evening celebrations. The Destination Blue Lagoon Schedule lists the same hours. On New Year’s Day, January 1, the spa returns to its full winter schedule of 08:00–22:00.

Is the Blue Lagoon in Iceland open in winter?

Yes, the Blue Lagoon is open year-round, including all winter months. The winter season runs from August 21 to May 31, with standard hours of 08:00–22:00 from August 21 to January 31, then shifting to 08:00–20:00 from February 1 to May 31 according to Destination Blue Lagoon. The official Blue Lagoon site lists the winter hours as 08:00–22:00 for the Aug 21–Jan 31 period.

What are the general winter opening hours?

From August 21 through January 31, the Blue Lagoon is open daily from 08:00 to 22:00. From February 1 to May 31, hours shorten to 08:00–20:00. Iceland.org confirms the same spring hours. During summer (June 1 to August 20) the hours extend to 07:00–00:00.

Does the Blue Lagoon close for maintenance in winter?

No, the Blue Lagoon does not close for annual maintenance during winter. It operates continuously. However, Guide to Iceland notes that temporary adjustments can occur, especially during periods of heightened volcanic activity — as seen in late 2024 when hours were temporarily reduced to 08:00–19:00 due to the Svartsengi eruption.

How does winter weather affect the visit?

Winter days in Iceland are short: daylight lasts roughly from 10:00 to 17:00. The contrast between the geothermal steam and the dark, cold air is part of the appeal. The Iceland.org guide highlights that the water temperature stays a constant 38°C regardless of outside conditions. Snow and wind are common, but the lagoon is sheltered. Bring warm clothes for the outdoor walkways.

Is 2 hours at Blue Lagoon enough?

For most visitors, two hours is enough to enjoy the lagoon, use the silica mud mask, and move between the steam cave and the outdoor pools. The Blue Lagoon Iceland site recommends 2–3 hours for a typical visit. The entry ticket includes access to the lagoon, a silica mask, and use of a towel. Many guests on forums like Guide to Iceland report that two hours feels sufficient, especially during winter when the cold air limits how long you want to stay in the water.

How long do most visitors spend?

Average visit duration is around 2 to 2.5 hours. The Blue Lagoon Iceland site states that the experience is designed to be “relaxed,” and most guests do not feel rushed. The spa does not enforce a strict time limit, but the entry ticket is for a specific time slot.

What can you do in 2 hours?

In two hours you can: change into your swimsuit, apply conditioner to your hair, enter the lagoon, visit the in-water mask bar, sit in the steam cave, enjoy the waterfall, and take a few photos. The Blue Lagoon Map shows the layout is compact — the main pool is about 5,000 square meters.

Is it better to book a longer session?

If you want to include the Retreat Spa, Lava Restaurant, or the Spa Restaurant, you’ll need more than two hours. The Iceland Highlights travel guide notes that the Lava Restaurant operates 11:30–21:00, so you could combine a soak with a meal. For a standard lagoon-only visit, two hours is plenty.

The trade-off: Two hours gives you the core experience without extra costs. Adding dining or spa treatments turns it into a half-day outing. Decide based on your schedule and budget.

Why can’t you wet your hair in Blue Lagoon?

The water in the Blue Lagoon contains high levels of silica — a mineral that can make hair brittle, stiff, and difficult to comb after it dries. The Blue Lagoon Iceland site advises against getting your hair wet, though it’s not forbidden. Many visitors choose to tie their hair up or wear a swim cap.

What happens if you wet your hair?

Silica particles bind to the hair shaft. When the water evaporates, the silica leaves a crystalline residue that can make hair feel like straw. The effect is more pronounced on light-colored or chemically treated hair. The Blue Lagoon Iceland site explains that the silica is the same mineral that gives the lagoon its iconic blue-white color.

How to protect your hair?

The Blue Lagoon provides free conditioner in the shower areas. Applying a generous amount of conditioner before entering the water creates a protective barrier. A swim cap offers the most reliable protection. The Blue Lagoon Iceland site recommends this step. After swimming, use the provided conditioner again to rinse out any remaining silica.

Are there any exceptions?

Some guests with short hair or very resilient hair report no issues after getting their hair wet. But the official recommendation from Blue Lagoon Iceland is clear: avoid submerging your hair, or use a cap. The silica is not harmful, but it is inconvenient.

The catch: The very thing that makes the water look magical — the silica — is also what can ruin your hair. The free conditioner is a helpful workaround, but it’s not a guarantee.

Is the Blue Lagoon poo water?

No, the Blue Lagoon is not “poo water.” The water is geothermal seawater, a mixture of freshwater and seawater heated underground by volcanic activity. The Blue Lagoon Iceland site describes it as “geothermal seawater” that is rich in silica, algae, and minerals. The blue color comes from the way silica reflects light, and the greenish tint is from algae.

What is the water source?

The water comes from the Svartsengi geothermal power plant, located right next to the lagoon. The plant extracts superheated water from 2,000 meters below the surface. The runoff water is rich in dissolved minerals and is then channeled into the Blue Lagoon. The Iceland.org guide clarifies that the water is naturally filtered through lava rock and is not wastewater.

Is the water clean?

Yes, the water is regularly tested for bacteria and chemical safety. The Blue Lagoon Iceland site states that the water meets Icelandic health standards. The lagoon is drained and refilled every few days, but the mineral content remains constant. The high temperature (38°C) and salinity also inhibit bacterial growth.

Why does it look blue?

The blue color is a result of the scattering of light by silica particles. The silica is white, but when suspended in water, it scatters blue light more than other colors, giving the lagoon its signature milky blue appearance. Algae also contribute a slight green tint. The Blue Lagoon Iceland site explains this phenomenon.

The implication: The “poo water” myth is pure internet folklore. The water is actually a natural geothermal byproduct that is clean, safe, and scientifically interesting.

Two different sources confirm the same message: the Blue Lagoon does not close for Christmas. The official Facebook post sets the winter schedule, while Iceland.org reinforces the year-round availability. Together they give visitors confidence that a holiday trip is feasible.

Plan your Christmas visit

For travelers heading to Iceland over the holidays, the Blue Lagoon is a reliable option with clear hours. The key takeaway: book your Christmas Eve slot early in the day, because the 16:00 closure means you’ll be out by sunset. For New Year’s Eve, you have until 18:00. Christmas Day offers the most relaxed timing. The volcanic activity in late 2024 did cause temporary hour reductions, so always check the official Blue Lagoon opening hours page before you go. For the average winter visitor, the decision is clear: pick a morning or early afternoon slot, protect your hair, and enjoy the geothermal steam while the snow falls around you.
