In the middle of the fissure on the Mid-Atlantic Ridge (in the south of Reykjanes) is the geothermal area Krysuvik. The main geothermal areas in Krysuvik are Seltun, Hverahvammur and Hverahlid. The banks around the hot springs are coloured green, yellow and red. Columns of steam rise skywards and the bubbling mud pools play their rhythmic symphony.

A well maintained boardwalk winds through the geothermal fields and visitors can find information and educational signs all around, explaining the geology of the geothermal area. Hikers can find a winding path leading to the top of the massive steaming vent, the view from the top is spectacular, of both the ocean, the geothermal fields and the lakes.
A few lakes are beside the mudpots and sulphur deposits. Lake Graenavatn, Gestsstadavatn and Augun (the Eyes) are explosion craters formed by volcanic eruptions. Lake Graenavatn, 150 feet deep, glows with rich, deep green colour, because of thermal algae and crystals that absorb sunlight.
The Krysuvik Geothermal Area of the Reykjanes Nature Reserve is where visitors can experience geothermal power in a more natural setting with boiling mud springs surrounding the world’s largest blowing steam vent. The nearby Seltun geothermal field is teeming with active hot springs, bubbling mud cauldrons and marked walking paths.
