Reykjanes Peninsula Lagoons
Blue Lagoon on Iceland's volcanic Reykjanes Peninsula — the most famous geothermal bathing area.
FeaturedBook NowBlue Lagoon
Immerse yourself in the world-famous Blue Lagoon, Iceland's most iconic geothermal spa, nestled within a dramatic lava field on the Reykjanes Peninsula. Its milky-blue, silica-rich waters, maintained at a constant 37–39°C, offer an unmissable luxury experience for every visitor.
Austurengjahver
Austurengjahver is an active geothermal mud spring in Austurengjar, south of Kleifarvatn on the Reykjanes Peninsula. Austurengjar is one of the principal geothermal areas within the wider Krýsuvík system, where steam, hot ground and mineral-rich mud reveal heat rising through the active volcanic landscape. This is a natural geothermal feature, not a bathing spring. Visitors should keep away from boiling mud, steam vents and thin crusts and avoid stepping off established safe ground.
Fúlipollur
Fúlipollur is a geothermal mud spring in the Krýsuvík high-temperature area near Seltún. Its name refers to the strong sulphurous smell, while mineral-rich geothermal activity colours the surrounding ground in grey, yellow and brown tones. Visitors should treat the ground as active geothermal terrain and remain on safe, established access routes.
Gunnuhver Geothermal Area
Gunnuhver Geothermal Area is a highly active geothermal site located on the southwestern tip of the Reykjanes Peninsula. The area is known for its large boiling mud pools, steam vents, and sulphur-rich geothermal activity, making it one of the most dramatic geothermal landscapes in Iceland. Unlike many geothermal bathing locations, Gunnuhver is far too hot for bathing, with temperatures exceeding boiling point in some areas.
Krýsuvík
Krýsuvík is a geothermal attraction in Reykjanes. Experience Iceland's powerful geothermal energy up close at this remarkable natural site. The area features hot springs, steam vents and mineral-rich waters that showcase the raw volcanic forces beneath Iceland's surface.
Reykjanesvirkjun
Reykjanesvirkjun is a 100 MW geothermal power station operated by HS Orka near the southwestern tip of the Reykjanes Peninsula. The plant uses high-temperature geothermal resources from the Reykjanes field and is cooled with seawater drawn from coastal wells. The site is industrial infrastructure rather than a hot spring or public bathing attraction. A former interactive exhibition called Orkuverið Jörð (Power Plant Earth) operated inside the plant for many years after opening in 2008, but HS Orka states that the exhibition was discontinued several years ago. General public traffic within HS Orka's operational area is prohibited.
Seltún
Seltún is an important high-temperature geothermal area in Krýsuvík with mud pots, fumaroles and colourful mineral deposits. A boardwalk and marked paths allow visitors to cross the active geothermal ground safely.
Skatalaug Hot Spring
Skatalaug is a natural hot spring located on the Reykjanes Peninsula, near Kleifarvatn lake in the Krysuvik geothermal area. This geothermal pool offers visitors a chance to relax in warm, mineral-rich waters surrounded by Iceland's stunning natural landscape. Perfect for those seeking an authentic Icelandic bathing experience away from the crowds.
Svartsengi
Svartsengi is one of the five major high-temperature geothermal areas of the Reykjanes Peninsula, located north of Grindavík. The field has been harnessed for district heating since 1976 and for electricity generation since 1978. Its geothermal system supplies hot water across the Reykjanes region, while mineral-rich brine from the power operation created the discharge pond that became the foundation of the Blue Lagoon. Svartsengi is also a place where Iceland's natural and human history overlap. The name comes from an old stopping place used by horsemen, while the modern landscape around the power plant has become a landmark of geothermal engineering, resource use and, since late 2023, renewed volcanic unrest beneath the area.
Valbjargagjá
Nestled within the rugged Reykjanes landscape, Valbjargagjá is a unique geothermal fissure transformed into a small, secluded pool. Once a community swimming spot, its moss-covered lava rock edges reflect the serene sky, hinting at a rich local history and ongoing restoration efforts.
