Gunnuhver

Gunnuhver (Icelandic: Gunnuhver) is an active geothermal area of hot springs, mud pools and fumaroles on the southwestern tip of the Reykjanes Peninsula in Iceland. It lies within the Reykjanes UNESCO Global Geopark and close to the Reykjanesviti lighthouse. The site has been the focus of safety measures and occasional closures due to changing geothermal activity.
