What you'll hear on this tour
Stop 1. Hverfjall Crater Hike
Dominating the Mývatn landscape, Hverfjall is one of the world's largest tephra explosion craters, formed in a single, colossal eruption approximately 2,700 years ago. Its perfectly circular rim, nearly a kilometer in diameter, invites visitors to hike its steep slopes for breathtaking panoramic views. From the summit, you can survey the surrounding pseudo-craters, vast lava fields, and the shimmering expanse of Mývatn lake. The sheer scale and dark, volcanic ash interior provide a tangible connection to Iceland's explosive geological past, making it a truly otherworldly experience.
Stop 2. Dimmuborgir's Dark Castles
Step into Dimmuborgir, also known as the "Dark Castles," a labyrinthine field of extraordinary lava formations. Legend claims this area is the home of the Yule Lads, Iceland's mischievous Christmas figures, and a gateway to the underworld. Formed over 2,300 years ago when a lava flow from a nearby eruption poured over a wetland, the molten rock cooled around steam vents, leaving behind towering pillars, arches, and caves. Wander through these natural sculptures and marvel at the intricate shapes created by the forces of fire and water, feeling the ancient stories embedded in the rock.
Stop 3. Hverir Geothermal Fields
Prepare for a sensory experience at Hverir, located at the base of Námafjall mountain. This highly active geothermal area is a symphony of hissing steam vents (fumaroles), bubbling mud pots (solfataras), and vibrant mineral deposits painting the ground in shades of orange, yellow, and red. The air is thick with the distinct scent of sulfur, a constant reminder of the volcanic activity simmering beneath the surface. As you walk the designated paths, you'll witness the raw, untamed power of the Earth, a stark and beautiful testament to Iceland's ongoing geological formation.
Stop 4. Grjótagjá Thermal Cave
Discover Grjótagjá, a small lava cave famous for its crystal-clear, geothermally heated water. Once a popular bathing spot, rising water temperatures in recent decades have made it too hot for swimming, though visitors can still admire its ethereal beauty. The cave sits directly on the Mid-Atlantic Ridge, where the North American and Eurasian tectonic plates slowly pull apart, creating dramatic fissures. Its dramatic lighting and unique geological setting made it a filming location for a popular fantasy series, adding to its mystique. Experience the quiet wonder of this subterranean thermal spring.
Stop 5. Skútustaðagígar Pseudo-Craters
Along the southern shore of Lake Mývatn, you'll encounter Skútustaðagígar, a series of unique pseudo-craters. Unlike true volcanic craters, these were not formed by erupting magma but by steam explosions. When hot lava flowed over the wetlands, trapped water beneath the surface rapidly turned to steam, causing localized explosions that built up these distinctive cone-shaped formations. These grassy mounds offer easy walking paths and provide stunning views over the lake and the surrounding landscape, perfectly illustrating the complex interplay of fire and water in Mývatn's geological history.
