Milky blue waters amidst a black lava field, steam rising into the crisp air, silica masks applied while laughing with friends: the Blue Lagoon is probably the most iconic image of Iceland. Depending on the season, the time of day and the weather, the experience changes completely: the light, the air temperature, the crowds. This guide brings together what you need to know to prepare your visit.
The Blue Lagoon is a man-made geothermal lagoon spanning around 10,000 m², fed by the wastewater from the Svartsengi power plant. Entry starts at ISK 11,990 (~€80) for the Comfort package, but prices are dynamic: they change depending on the date, time and demand. Since late 2023, the Reykjanes Peninsula has experienced intense volcanic activity, with nine eruptions between December 2023 and August 2025: the Blue Lagoon has closed and reopened multiple times, and its car park was even destroyed by lava in November 2024.
This guide covers everything: 2026 prices, access from Reykjavik and Keflavík Airport, volcanic impact, the on-site experience, restaurants, accommodation and alternatives. Whether you're torn between Comfort and Premium, or wondering if the Blue Lagoon is really worth the price, you'll find your answers here.
Why is the Blue Lagoon so famous?
Imagine, after a long day of travel, sinking into turquoise waters at 38 °C, surrounded by black lava formations covered in moss. The Nordic sky: whether streaked with northern lights in winter or bathed in midnight sun in summer: completes the picture. It's one of those places on almost every traveller's Iceland bucket list. And for good reason.
The lagoon stretches across around 10,000 m² of milky blue geothermal water, a natural hue created by suspended silica that reflects light. The water comes from deep underground, about 2,000 metres below the surface, before being used by the Svartsengi power plant and then discharged into the porous lava field. The result: a lagoon whose temperature hovers between 37 °C and 40 °C, all year round.
The contrast between the milky blue water and the black lava is striking. Located just 20 minutes from Keflavík Airport, it's often the first or last stop for many travellers: a detour that fits naturally into any itinerary.
History and origins of the Blue Lagoon
When nature meets man
The Blue Lagoon is not a natural hot spring in the strict sense. Its story begins in the 1970s, when the Svartsengi geothermal power plant began operating on the Reykjanes Peninsula. Geothermal water, pumped from 2,000 metres underground to generate electricity and heating, was discharged after use into the surrounding lava field. Rich in silica, algae and minerals, this water accumulated in the cavities of the porous lava, forming a lagoon with milky blue reflections.
An unexpected place of healing
In the 1980s, locals began bathing in this warm-water reservoir. They soon noticed that the water seemed to have beneficial properties for the skin, especially for people suffering from psoriasis. A local dermatologist, Dr Grímur Sæmundsen, launched a clinical study that confirmed the benefits of silica and algae for skin conditions. Word spread and attracted more and more bathers.
From discovery to worldwide fame
In 1992, the Blue Lagoon officially opened its doors to the public as a bathing complex. Since then, its reputation has only grown: from a simple outdoor pool, it has transformed into a luxury resort with hotels, Michelin-starred restaurants and a cosmetics line. Today, it welcomes around 1.3 million visitors per year, making it Iceland's most visited tourist attraction.
The Blue Lagoon is far more than a tourist attraction: it has become a symbol of the harmony between man and nature in Iceland. To discover the country's other treasures, explore our Iceland destinations section.
What makes the Blue Lagoon special
Waters with exceptional properties
The Blue Lagoon's water is a blend of 65% seawater and 35% freshwater, naturally heated by underground volcanic activity. Its chemical composition is unique: approximately 140 mg/L of silica, blue-green algae, sulphur and mineral salts. The pH is around 7.5 (slightly alkaline), and the water contains no chlorine, it is naturally renewed every 40 hours. The average depth is 1.2 metres, which allows you to move around comfortably standing up.
After soaking, you feel a real sense of freshness and renewal on your skin. Conditions like psoriasis or eczema seem to fade, leaving skin feeling soft and radiant. And the blue colour? It's caused by suspended silica that reflects visible light: the higher the concentration, the more intense the blue.
A breathtaking landscape
The Blue Lagoon's setting is breathtaking. Surrounded by black lava fields covered in moss and distant mountains, the contrast with the milky blue water is striking. In winter, the steam rising into the freezing air creates a dreamlike atmosphere, and you can sometimes catch the northern lights while bathing. In summer, the midnight sun offers incomparable golden light.
Sustainability and geothermal energy
The Blue Lagoon is an example of smart reuse of geothermal resources. The water that feeds the lagoon is a by-product of the Svartsengi power plant, which provides electricity and heating to 30,000 residents of the Reykjanes Peninsula. Rather than being discarded, it is channelled into the lagoon where it creates this unique experience. The entire site runs on renewable energy.
Blue Lagoon and volcanic activity: what you need to know
Since December 2023, the Reykjanes Peninsula has been experiencing a period of intense volcanic activity. Nine eruptions occurred between December 2023 and 2025, all within the Sundhnúkur fissure system, just a few kilometres from the Blue Lagoon. The site temporarily closed several times as a safety precaution.
October 2026 update: there has been no new eruption since August 2025. As of 30 September 2026, the Icelandic Met Office (vedur.is) still records slow ground uplift beneath Svartsengi, a sign that magma keeps accumulating, and considers a new magma intrusion that could lead to an eruption on the Sundhnúkur crater row the most likely scenario. Check the current situation before your visit.
The November 2024 eruption was the most impactful: the lava flow destroyed part of the Blue Lagoon's car park and damaged nearby road infrastructure. Protective earth barriers (berms) were erected around the site and the town of Grindavík to divert potential future lava flows.
The Blue Lagoon has implemented rigorous evacuation protocols: seismic sensors monitor activity in real time, and in the event of an alert, the site can be evacuated within minutes. Staff are trained in emergency procedures, and evacuation routes are clearly marked.
Despite this context, the Blue Lagoon continues to welcome visitors whenever conditions allow. The situation is closely monitored by the Icelandic authorities, and visitor safety remains the absolute priority. The experience is just as spectacular: some would even say the renewed volcanic landscape adds to the magic of the place.

How to get to the Blue Lagoon
By car
The Blue Lagoon is located at Norðurljósavegur 9, 240 Grindavík, on the Reykjanes Peninsula. From Reykjavik, allow about 50 km / 45 minutes via Route 41 then Route 43. From Keflavík Airport (KEF), it's only 20 km / 20 minutes. The road is well-maintained and easy to follow.
A tip: enter the GPS coordinates into your device rather than the name 'Blue Lagoon', as some GPS systems redirect to the old entrance. For car hire, check our guide to renting a car in Iceland. If you're arriving by air, our article about Keflavík Airport will come in handy.
By shuttle
If you'd rather not drive, Destination Blue Lagoon shuttles run regularly from BSÍ Bus Terminal in Reykjavik and from Keflavík Airport. Fares are listed on the Destination Blue Lagoon website. The buses are comfortable and their schedules are aligned with the lagoon's entry time slots. Book them at the same time as your admission ticket on the official website.
Blue Lagoon opening hours
The Blue Lagoon's hours vary by season. Here are the four periods for 2026:
- 1 February to 31 May (spring): 8 am to 8 pm
- 1 to 14 June: 8 am to 10 pm
- 15 June to 20 August (summer): 7 am to 11 pm
- 21 August to 31 January (autumn and winter): 8 am to 10 pm
Guests must leave the water 30 minutes before closing. Hours may be adjusted due to volcanic activity or extreme weather: always check the official website before your visit.
The Blue Lagoon in winter
Winter may be the most beautiful season at the lagoon: the water stays between 37 and 40 °C while the air drops below freezing, and the steam wraps around the bathers. A few things change your plans, though.
- Daylight: around 21 December, it is light from about 11:20 am to 3:30 pm. A midday slot gives you daylight; an evening slot gives you the night sky.
- Northern lights: on clear nights with good activity, they can appear above the lagoon from September to April. The site's lighting gets in the way a little, so don't book for them alone.
- Holidays: opening hours change on 24, 25 and 31 December and 1 January, and these slots sell out fast. Book early and check them on the official website.
- Road: from Reykjavik or Keflavík, routes 41 and 43 are maintained, but wind, ice and snowstorms can close them. Check umferdin.is for road conditions and vedur.is for wind warnings before you set off. Without a car, the shuttles spare you a night drive.
- On site: the path from the car park to the entrance can be icy, and wet hair freezes quickly outside: keep a hat for the walk back.

The on-site experience
Lagoon zones
The Blue Lagoon is divided into several zones, each with its own atmosphere. The main area offers the vast expanse of blue water between lava rocks. The sauna is nestled in a lava cave with a panoramic view over the lagoon, a favourite when it's cold outside. The steam room is more intimate and ideal for warming up between dips.
You'll also find relaxation areas with sun loungers, some set in caves. And the in-water bar lets you order a drink, smoothie, beer or cocktail, and sip it while floating. Your electronic wristband serves as payment throughout the site.
Treatments and masks
The white silica mask is included in all packages: you'll find it at self-service stations around the lagoon. Apply it to your face, leave for 10 minutes, then rinse. With the Premium package and above, you get access to additional masks (green algae and lava mask) at dedicated mask stations.
For a massage or a more comprehensive treatment, the spa offers therapies by reservation, including floating massages performed directly in the water.
Blue Lagoon restaurants
Moss Restaurant: Michelin star
Perched at the highest point of the site, Moss received its first Michelin star in 2023. Under chef Agnar Sverrisson (formerly of Texture Restaurant in London, starred for 10 years), Moss serves reimagined Icelandic cuisine with Asian touches. The tasting menu costs ISK 39,900 (~€265), excluding wine pairing; it is served Wednesday to Sunday evenings, from age 12. Reservation essential: directly on the Blue Lagoon website.
Lava Restaurant: casual Icelandic cuisine
Set against an 800-year-old lava cliff, Lava serves Icelandic cuisine with a view of the lagoon. It's the only restaurant where you can have lunch in your bathrobe, until 3 pm; a table can be added as an option when booking your entry. Menu, prices and tips: see our article on the Lava restaurant (in French).
Blue Café
For a quick break: coffee, pastries, sandwiches and soups. Ideal before or after your soak. Prices are more reasonable than at the restaurants.
In-Water Bar
The bar right in the lagoon. Smoothies, beers, cocktails, wine: you order with your electronic wristband and sip your drink while floating. Your first drink is included in all packages.
Blue Lagoon skincare products
The Blue Lagoon has developed its own range of cosmetics made from the minerals in its waters. Here are the must-haves:
- Silica Mud Mask: the iconic silica mud mask. Purifies and smooths the skin. It's the same one available self-service in the lagoon.
- Algae Mask: mask made from the lagoon's blue-green algae. Deeply hydrates and soothes sensitive skin.
- Lava Scrub: exfoliating scrub made from lava and silica. Gritty texture, effective for prepping the skin.
- BL+ Serum: the premium product in the range. A serum concentrated with silica, algae and minerals for a daily skincare routine. Pricey (~ISK 15,000 / ~€100) but highly rated.
You can buy these products at the Blue Lagoon shop or online. They make excellent souvenirs to bring back from Iceland.
Where to stay near the Blue Lagoon
The Retreat at Blue Lagoon
The most exclusive hotel in the area, integrated into the Blue Lagoon site. Private access to the Retreat Lagoon, luxurious suites with views over the lava field, spa and Moss restaurant on site. Waking up with the lagoon at your feet is a true privilege. Rates start around ISK 230,000 (~€1,550) per night: it's top-end luxury, reserved for special occasions.
Northern Light Inn
Located 200 metres from the Blue Lagoon entrance, this is the most practical option for decent value. Comfortable rooms, on-site restaurant, and above all the ability to walk to the lagoon. Rates vary by season; check the hotel's website.
More affordable options
If you're on a tighter budget, several options exist in the area:
- Grindavík: 10 minutes by car, the town evacuated in November 2023 remains heavily affected by volcanic activity; check whether accommodation has reopened before booking.
- Accommodation in Keflavík: 20 minutes away, with more choice and price ranges. Convenient if you're arriving or departing by air.
- Reykjavik: 45 minutes by road, it's the most flexible option if you're visiting the Blue Lagoon as a day trip.
Other nearby attractions
The Reykjanes Peninsula is full of remarkable sites to explore before or after your visit to the Blue Lagoon.
Grindavík
This fishing village has been deeply affected by the recent volcanic activity. In November 2023, the entire population had to be evacuated, and cracks opened in some streets. Despite these hardships, Grindavík shows remarkable resilience. The harbour remains active, and the village stands as a poignant testament to life on an active volcanic land. Respect closed areas and follow local guidance if you decide to visit.
Reykjanes lava fields
The peninsula is famous for its vast lava fields, some of which are very recent: the 2023-2025 flows have reshaped the landscape. The moss-covered rock formations, fumaroles and natural hot springs create a mystical, almost otherworldly atmosphere.
Reykjanesviti lighthouse
Perched on a wave-battered cliff, Iceland's oldest lighthouse offers a panoramic view of the Atlantic Ocean. On a clear day, the sunset is spectacular. The access road winds through a landscape of fumaroles and hot springs.
Bridge Between Two Continents
Iceland sits at the junction of two tectonic plates: the Eurasian and the North American. On the Reykjanes Peninsula, a symbolic bridge spans the rift between the two plates. It's a strange and wonderful feeling to stand on the boundary of two continents, and the souvenir photo is a must.

Alternatives to the Blue Lagoon
The Blue Lagoon is not Iceland's only geothermal bath, and if the prices or the crowds put you off, here are some alternatives:
- Sky Lagoon (Reykjavik): opened in 2021, this seaside lagoon offers a stunning view of the Atlantic. The atmosphere is more intimate than at the Blue Lagoon, with a 7-step ritual. Prices on the official website. A different experience, and easier to reach from Reykjavik.
- Hvammsvík (Hvalfjörður): natural pools on the edge of a fjord, about an hour from Reykjavik, some of them washed by the tide.
- Hrunalaug (Golden Circle): a small, rustic hot spring with a turf hut, far from the resort feel.
- Earth Lagoon Mývatn, formerly Mývatn Nature Baths (North): the northern alternative, much less crowded. Similar milky water, spectacular volcanic scenery, and a gentler price (from ISK 7,400, about €50). The drive from Reykjavik is long (5 h), but if you're doing the ring road, it's an obvious stop.
- Secret Lagoon (Flúðir): Iceland's oldest geothermal pool (1891). Rustic and authentic atmosphere, without the resort feel. ISK 4,500 (about €30). Small, but charming.
- Vök Baths (East): floating pools on Lake Urriðavatn, in eastern Iceland. Minimalist design, low footfall, superb natural setting. Prices on the official website.
In short, the Blue Lagoon remains a unique experience thanks to its sheer size, colour and facilities. But if it's your second or third trip to Iceland, explore the alternatives: they often offer a more authentic atmosphere and fewer crowds.
Practical information for your visit
Photos and videos
Photography is permitted at the Blue Lagoon, including smartphones and cameras. However, respect other visitors' privacy and avoid intrusive photos. Protect your device with a waterproof case: the silica-rich water is not kind to electronics. Drones are prohibited on site.
Luggage storage
The Blue Lagoon has a free luggage storage where you can safely store your suitcases during your visit. It's especially handy if you're coming straight from Keflavík Airport or heading there right after.

A swimsuit is mandatory. If you forgot yours, you can buy or rent one at reception. Tip: wear it under your clothes to save time in the changing rooms. There is no swimsuit dryer, bring a plastic bag for the return journey.
The Comfort package starts at ISK 11,990 (~€80). Prices are dynamic and vary by date, time and demand. Premium starts from ISK 14,990 (~€100) and the Retreat Spa from ISK 89,000 per private changing room (up to two guests).
Yes, online booking is mandatory. There are no tickets sold on site. In peak season, popular time slots (11 am-4 pm) fill up several days in advance. Book as soon as your travel dates are confirmed.
Allow between 2 and 4 hours on site. There is no time limit once you're in, but most visitors spend around 2 to 3 hours in the water.
The water is kept between 37 °C and 40 °C (99-104 °F) all year round. The temperature varies slightly depending on the zone, some pockets are warmer than others.
The Blue Lagoon has strict evacuation protocols and monitors seismic activity in real time. The site closes preventively as soon as a risk is identified. Check the status on bluelagoon.com and safetravel.is before your visit.
Yes, children aged 2 and over are admitted. Ages 2-11 have a dedicated booking category. An adult must accompany children in the water, with a maximum of 2 children under 8 per adult.
Keflavík Airport (KEF) is only 20 km / 20 minutes by car from the Blue Lagoon. Shuttles are also available. It's an ideal stop on the way in or out of Iceland, especially as luggage storage is free.
A swimsuit (mandatory) and optionally flip-flops. A towel is provided with all packages. A bathrobe is included from the Premium package. Remove any silver jewellery before entering the water.
The milky blue colour comes from suspended silica in the water (approximately 140 mg/L). The silica particles reflect visible light, creating the characteristic hue. The higher the concentration, the more intense the blue.
Yes, four options: Moss (Michelin star, menu ISK 39,900), Lava (Icelandic casual, accessible in bathrobe), Blue Café (snacks and drinks), and the In-Water Bar (in the lagoon, first drink included).
It's a unique experience thanks to the combination of geothermal water, volcanic landscape and quality facilities. The Comfort package already covers the essentials. If budget is tight, morning or evening slots are often cheaper.
Sky Lagoon (Reykjavik) offers an Atlantic view, Earth Lagoon Mývatn (north, from ISK 7,400) is less crowded, Secret Lagoon (Flúðir, ISK 4,500) is the most authentic, and Vök Baths (east) is the most secluded.
Yes, all year round. In 2026 it opens from 8 am to 10 pm from 21 August to 31 January, then from 8 am to 8 pm from 1 February. Hours change on 24, 25 and 31 December and 1 January, and the site may close during storms or volcanic alerts.
It is possible from September to April, on clear nights with good solar activity, with an evening slot. The site's lighting gets in the way a little, so treat them as a bonus.
Conclusion
The Blue Lagoon remains one of Iceland's most iconic experiences, and despite rising prices and volcanic activity, it continues to offer a moment of pure magic. The milky blue water, the contrast with the black lava, the enveloping warmth when the Icelandic air nips at your face: it's a memory that stays with you.
Our advice: book early, favour the morning or late afternoon, and don't skip the conditioner before getting in the water. If you visit in winter, you might be lucky enough to spot the northern lights from the lagoon: an unforgettable spectacle.
