Gunnuhver is a stunning geothermal area known for having one of the most powerful fumaroles in Iceland. This sulfur-rich, bubbling mud region is located just a few kilometers from Keflavík International Airport, making it a must-visit destination.

The area is named after Guðrún (Gunna), a ghost from local folklore who caused trouble until a priest trapped her spirit here. Today, Gunnuhver is a popular tourist attraction, offering visitors a glimpse of the Earth’s raw power.

If you enjoy such smoky and sulfurous places, your next stop could be the Seltún-Krýsuvík geothermal area.

Gunnuhver is situated at the far southwest of the Reykjanes Peninsula and takes on an unparalleled character at sunset.
