About the Blue Lagoon
Blue Lagoon, Iceland is a geothermal spa on the Reykjanes Peninsula in southwest Iceland, fed by mineral-rich seawater processed through the nearby Svartsengi geothermal power station. The lagoon's water contains silica, algae, and minerals, which give it its signature milky blue colour and are the basis of the Blue Lagoon's skincare range. Water temperature in the main bathing area averages 37 to 39 degrees Celsius, and the water is completely refreshed approximately every 48 hours without the use of chemicals or additives. The lagoon itself is a man-made basin set into a lava field, combining engineered infrastructure with a natural geothermal water source.
The site originated in 1976 when the Svartsengi geothermal power plant began pumping superheated water from deep below the earth. The released mineral-rich water accumulated in a natural depression in the lava field, and in 1981 the first person was documented bathing in the milky blue water. The Blue Lagoon company was formally established in 1992, a psoriasis clinic opened in 1994, and the site has since grown into Iceland's most visited single attraction. The facility now includes two on-site hotels, multiple restaurants including Michelin-starred dining at Moss, the Retreat Spa, a skincare store, and an in-water bar. It sits within a wider landscape of lava fields and volcanic terrain that has been reshaped repeatedly by eruptions on the Reykjanes Peninsula.
The Blue Lagoon is among the most developed geothermal pools in Iceland in terms of infrastructure, commercial offering, and visitor numbers, recording approximately 1.3 million visitors in 2017. It is named among National Geographic's 25 Wonders of the World. For visitors looking for hot springs near Reykjavík with full facilities, direct airport access, and a world-recognised spa experience, it occupies a category of its own among all geothermal sites in Iceland.
Location & Access
Getting to the Blue Lagoon
The Blue Lagoon is located at Norðurljósavegur 9, 240 Grindavík, on the Reykjanes Peninsula in southwest Iceland. From Keflavík International Airport, the drive takes approximately 20 minutes heading south on Road 41 and then onto the access roads toward Grindavík. From Reykjavík, the drive is approximately 47 kilometres and takes 40 to 45 minutes under normal traffic conditions. Free parking is available on site, and all car park walkways are paved and wheelchair accessible.
Due to ongoing volcanic activity on the Reykjanes Peninsula, the standard access route to the Blue Lagoon has been subject to periodic closures since late 2023. As of early 2026, visitors are directed to use Road 44 (Hafnarvegur) rather than the older route through Grindavík. Some GPS and navigation apps may not reflect the updated routing. Always check the official Blue Lagoon website for current access information before travelling. The Blue Lagoon monitors volcanic and seismic activity daily and will close if conditions require it; checking their website on the day of your visit is advised, particularly during periods of elevated volcanic activity in the Reykjanes area.
Pre-booking is required. The Blue Lagoon does not permit walk-in entry, and all visits must be booked in advance for a specific entry time slot. During peak summer months, tickets sell out weeks in advance. The Blue Lagoon is also accessible by direct bus transfers from Reykjavík hotels and from Keflavík Airport, and is a frequent stop on organised day tours. For those looking for hot springs near Reykjavík with bus and tour connections, this is the most accessible geothermal spa option from the capital by public transfer. Once inside, there is no time limit on your visit and no re-entry once you exit.
Suitability & Accessibility
Who Can Visit the Blue Lagoon
The Blue Lagoon suits a wide range of visitors, from families with children to solo travellers, couples, and visitors with mobility requirements. It is the most fully accessible geothermal pool in Iceland, with elevators, electric door openers, wheelchair-accessible changing rooms, specially designed waterproof wheelchairs for entering the lagoon via a ramp, and a shower chair available on request. Guests who require assistance in the changing rooms or in the water can bring a personal assistant free of charge, by arrangement in advance.
Children aged 13 and under enter free when accompanied by a parent or guardian. The minimum age for entering the lagoon is two years old, as younger children are sensitive to the water's elevated mineral content. Children aged eight and under must wear arm floaters in the water, which are provided free of charge. The Blue Lagoon is therefore suitable for families with children of school age and above. Those with very young infants should note the minimum age restriction.
The Blue Lagoon offers four entry packages at different price points: Comfort (the base tier), Premium, Signature, and the Retreat Spa (a separate subterranean spa experience). Each package adds different inclusions such as bathrobes, skincare gifts, in-water treatments, and dining. All packages include use of the main lagoon. The facility also provides accessible hot springs in Iceland for visitors in wheelchairs, with confirmed full infrastructure support that makes it the clearest recommendation for any visitor who requires assistance getting into geothermal water. Pricing follows a dynamic model and varies by date, time, and how far in advance tickets are booked.
Safety & Etiquette
Safety and Etiquette at the Blue Lagoon
The Blue Lagoon is generally safe to visit as a fully staffed commercial spa with trained lifeguards on every shift, at least two per session, one in an elevated tower with a view of the entire bathing area and another circulating at water level. The lagoon depth is 90 to 140 centimetres throughout most of the bathing area. Water temperature averages 37 to 39 degrees Celsius in the main lagoon, which is within the comfortable soaking range for most healthy adults. Visitors who are pregnant, have cardiovascular conditions, or are sensitive to heat should consult a doctor before visiting and should limit soaking time accordingly.
All guests are required to shower thoroughly without a swimsuit before entering the lagoon. This is standard Icelandic pool etiquette and is enforced by staff. Jewellery, particularly silver, can be discoloured by the mineral-rich water and should be removed before entering. Hair can also be affected by the silica content; conditioner is available in the changing rooms and using it before entering the water is recommended. Blue Lagoon shower gel and conditioner are provided free to all guests.
The Reykjanes Peninsula is a seismically and volcanically active area. The Blue Lagoon monitors conditions in real time with gas sensors and a weather station, in cooperation with Icelandic authorities. The facility closes if conditions are deemed unsafe, and an evacuation plan is in place and regularly practised by trained staff. Visitors should follow any instructions from Blue Lagoon staff immediately and without delay. Before travelling, always check the Blue Lagoon website for any access or safety advisories related to volcanic activity in the Grindavík area, as road conditions and access routes can change without advance notice.
