The geothermal area Krýsuvík is situated on the Reykjanes peninsula in Iceland. It is in the south of Reykjanes in the middle of the fissure zone on the Mid-Atlantic Ridge which traverses Iceland.

Krýsuvík consists of several geothermal fields, such as Seltún. Here solfataras, fumaroles, mud pots and hot springs have formed, the soil is coloured bright yellow, red, and green hues. Sulphur deposits were mined in 1722 – 1728 and in the 19th century. German scientist Robert Bunsen visited the site in 1845 and, based on research there, proposed a hypothesis on formation of sulphuric acid in nature.

Near the geothermal fields are several maars – craters created by the explosions of overheated groundwater. The unusual green-blue Grænavatn lake has formed in one of these maars. Test boreholes were made here in the early 1970s, some of the boreholes have turned into irregular, artificial geysers, one of which exploded in 1999, leaving a crater.

The Blue Lagoon (Icelandic: Bláa lónið) geothermal spa is one of the most visited attractions in Iceland. The spa is located in a lava field in Grindavík on the Reykjanes Peninsula, southwestern Iceland. Bláa lónið is situated approximately 20 km (12 mi) from the Keflavík International Airport and 39 km (24 mi) from the capital city of Reykjavík, roughly a 20 minute drive from the airport and a 50 minute drive from Reykjavík.

The warm waters are rich in minerals like silica and sulfur and bathing in the Blue Lagoon is reputed to help some people suffering from skin diseases such as psoriasis.[2] The water temperature in the bathing and swimming area of the lagoon averages 37–39 °C (99–102 °F). The Blue Lagoon also operates a research and development facility to help find cures for other skin ailments using the mineral-rich water. The lagoon is a man-made lagoon which is fed by the water output of the nearby geothermal power plant Svartsengi and is renewed every two days. Superheated water is vented from the ground near a lava flow and used to run turbines that generate electricity. After going through the turbines, the steam and hot water passes through a heat exchanger to provide heat for a municipal water heating system. Then the water is fed into the lagoon for recreational and medicinal users to bathe in.

Iceland has a strict code of hygiene and guests are required to shower before bathing.
