Iceland's best-known geothermal spa in a lava field on the Reykjanes peninsula, near Keflavik airport, with milky blue silica-rich water and an in-lagoon bar.
The Blue Lagoon is a geothermal spa set in a lava field at Svartsengi on the Reykjanes peninsula, about 50 km from central Reykjavik and about 20 minutes from Keflavik airport. Its milky blue water is rich in silica and minerals and is kept at roughly 37-40 degrees Celsius. The Comfort ticket, the base entry, includes lagoon entry, a silica mud mask, a towel and one drink; third-party guides list Comfort from about ISK 9,990-11,990 (~$80-96), though prices rise with demand and fall for early-morning slots. Premium and Retreat packages add robes, extra masks and spa access, and the Retreat Spa is a separate subterranean spa complex.
The area has been affected by volcanic activity on the Reykjanes peninsula since 2021, and the lagoon has closed temporarily during eruptions and evacuations. Visitors should check bluelagoon.com and vedur.is for current status and reserve a time slot online in advance; walk-up entry is generally unavailable. Shuttle buses run from BSÍ in Reykjavik and from Keflavik airport, and many travellers visit on the day of arrival or departure. Swimwear is required, and the shower-before-entry rule applies. Keep hair out of the water or apply conditioner, since silica dries hair.
