Volcanic Springs

Geysers, Hot Springs,
Mud Pots, and Fumaroles

Gunnuhver, Power Plant Basin Group

Looking northwest from Kísilhóll a steaming plain in front of the collecting basin (Gráa Lónið, gray lagoon) comes into view. The plain called Hveravellir is home of several fumaroles and mud pots, but there is no direct access from Kísilhóll.

To observe the features of the Power Plant Basin Group at closer range, follow the unpaved road west of the thermal area until you reach a branch in direction of the power plant basin. In contrast to the highly dangerous area between the thermal features the rim of the basin is a safe observation point. Silica rich water, dicharged from the geothermal power plant, causes its muddy blue color.

The area in front of the power plant basin comprises a fascinating collection of mud pots. Some of them are very active spouters.
