Amazing geothermal area full of boiling mud and with one of the most powerful fumarole in Iceland, place fully filled with sulfur – that´s Gunnuhver. It is just few kilometers/miles away from Keflavík International Airport, so it should be part of your Icelandic itinerary.
If you like geothermal areas full of smoke and sulfur like this, Seltún-Krýsuvík might be your next stop.
At the southwestern part of the Reykjanes peninsula.
