When it comes to exploring Iceland’s glaciers, most travelers stick to the popular spots like Jökulsárlón or Svínafellsjökull. But for those who crave a truly unique experience that combines adventure, education, and a dash of scientific contribution, the Krossárjökull Glacier Mapping Adventure from Vik really hits the mark. This tour isn’t just about snapping photos of pretty ice; it’s about stepping into the role of a Citizen Scientist and helping monitor one of Iceland’s less-visited glaciers.
What makes this adventure stand out? First, you get to drive through the stunning Thorsmork highlands, a landscape often described as otherworldly. Second, the trek through a secluded canyon offers a rare glimpse into Iceland’s untouched wilderness—far from crowded trails. Third, the opportunity to contribute to glacier monitoring adds a meaningful layer to the experience. The only caveat? It’s a moderate physical activity tour, so it’s best suited for travelers comfortable with outdoor adventures—and not suitable for very young children or those with mobility issues.
This experience is perfect if you’re after something genuinely different from the usual Icelandic excursions. It’s ideal for eco-conscious travelers, nature lovers, and anyone eager to learn how climate change impacts glaciers firsthand. Just be prepared for a long day, packing your sense of adventure along with your waterproof gear.

The Journey Begins: Drive through Thorsmork
Starting at the N1 Gas Station in Hvolsvöllur, the day kicks off with a scenic 4×4 drive through the legendary Thorsmork highlands. Known for its dramatic landscapes of jagged mountains, glaciers, and rivers, Thorsmork is often called “Thor’s forest” because of its mythic associations. During the drive, you’ll get to marvel at glacier-fed rivers crossing the road, colorful mountain formations, and vast wilderness that seem untouched by time.
Guests often comment on the stunning scenery and the thrill of navigating the rugged terrain in a specially equipped vehicle—an experience in itself. One reviewer noted, “The landscape here is like nothing I’ve seen anywhere else. The colors, shapes, and the feeling of being on the edge of wilderness is indescribable.”
Trekking to the Glacier
Once in the vicinity of Krossárjökull, the group prepares for a moderate 1-1.5 hour trek through a hidden canyon. This offbeat trail is far from the typical tourist routes, leading you through a natural corridor carved by the glacier itself. You’ll be guided by knowledgeable experts who provide a detailed safety brief and teach you how to use the mapping equipment.
The hike offers a chance to see dead ice formations, deep blue crevasses, and the glacier’s edge, which is often cloaked in a veil of mist or snow. As one reviewer shared, “The natural beauty of the glacier’s features left me speechless. The quiet and the scale of it made me feel like I was in a different world.”
Contributing as a Citizen Scientist
This is not your average sightseeing tour. Your team will participate in mapping the glacier terrain, helping to gather data about its shape, features, and changes. The expert guides are also scientists, providing engaging insights into the glacier’s history and its role within Katla Geopark.
The training is straightforward, focusing on how to operate the equipment safely and effectively. Several reviewers appreciated the chance to actively participate in important research, with one saying, “It felt good knowing I was helping scientists understand this glacier’s health. It’s something I’ll remember forever.”
More Great Thing To Do NearbyLunch with a View
Midday, you’ll enjoy a packed lunch surrounded by breathtaking scenery—think panoramic views of ice, mountains, and sky. This break is the perfect time to take photos, ask questions, or simply soak in the pristine environment. Many guests mention how this moment of stillness and natural beauty makes the experience all the more memorable.
Wrap-up and Results
At the end of the day, you’ll receive a Citizen Scientist Certificate from Katla Geopark, along with the mapping data collected during your expedition. The results are emailed afterward, giving you a tangible sense of contribution. One reviewer noted, “It’s incredible to think that the data we gathered will help scientists monitor climate changes for years to come.”
