Reykjanes peninsula: Volcanoes & Hot Springs

The Stampar Volcanic Craters form one of the Reykjanes Peninsula's most striking geological features, a series of perfectly preserved ancient craters stretching across the landscape like a timeline of volcanic activity. Walking among these thousands-of-years-old formations offers an intimate encounter with the forces that built Iceland, from smooth pahoehoe flows to rough a'a lava. The contrast between dark volcanic rock and vibrant green mosses creates some of the most photogenic scenery on the peninsula.

Gunnuhver is Iceland's most powerful geothermal area, where enormous steam plumes and bubbling mud pools embody the raw energy beneath the Reykjanes Peninsula. Named after the legendary ghost Gunna, trapped within the vents during a 17th-century exorcism, this site blends natural spectacle with rich Icelandic folklore. Boardwalks allow safe exploration through hissing steam, colorful mineral deposits, and underground temperatures exceeding 300°C.

The Fagradalsfjall Lava Field is one of Earth's newest volcanic landscapes, created during the spectacular 2021-2023 eruptions. Visitors can walk across lava that was molten just years ago, where the ground still retains warmth and fresh formations showcase the immediate aftermath of geological creation. The pristine black lava fields, with gas bubbles frozen in cooling rock and intricate textures of solidified magma, contrast dramatically with gradually returning vegetation, a vivid reminder that this landscape could resume its story of creation at any moment.

Seltún is one of Iceland's most visually stunning geothermal areas, where brilliant yellows, oranges, reds, and greens created by sulfur compounds and iron oxides paint a surreal landscape. Bubbling mud pots and steaming fumaroles fill the air with mineral-rich vapor and the distinctive aroma of sulfur. Elevated boardwalks allow safe exploration of this delicate ecosystem, where each vent connects directly to magma chambers exceeding 1000°C beneath the Reykjanes Peninsula.

The Lava Tunnel takes you underground through a spectacular volcanic formation created thousands of years ago, when flowing lava hardened on the outside while the molten interior drained away, leaving a magnificent subterranean passageway. Inside, colorful mineral deposits, lava stalactites, and unique rock textures tell the story of Iceland's volcanic heritage. The cool temperature allows ice formations and volcanic rock to coexist in striking harmony, offering a rare chance to walk through the very arteries of an ancient volcanic system.

The Geothermal Exhibition is the perfect educational complement to your volcanic exploration, showcasing how Iceland has become a world leader in sustainable energy by harnessing the very forces you have witnessed throughout the day. Interactive displays and detailed models explain how underground heat is transformed into electricity and heating for Icelandic communities. This essential stop connects Iceland's volcanic heritage to its position as a global pioneer in renewable energy innovation.
