East of Reykjanes lighthouse is Gunnuhver the most famous of many high temperature
geothermal areas in Reykjanes. The name is derived from a woman called Guðrún, a spectre
who caused great disturbance until Eiríkur Magnússon, a priest at Vogsósar, set a trap for her
and she fell into the hot spring. The nature at Gunnuhver is very beautiful and it is popular for
hiking. In April 2008 the vapour activity had increased a lot and the hot spring now covers a
larger area as well as increasing mud eruptions.Explosions which whisk steaming mud can
follow such mud eruptions. people have to use caution when they visit the area and keep a
distance from the spring itself.
