Discover Iceland's hidden glacier with a 10-hour mapping adventure, scenic drives, canyon hikes, and contributing to real climate research.
Exploring Iceland’s wild landscapes often means sticking to well-trodden paths, but the Krossárjökull Glacier Mapping Adventure offers something quite different. This full-day experience combines scenic drives, offbeat hikes, and hands-on scientific contribution—a rare blend of adventure and purpose. It’s an opportunity to step into the shoes of a Citizen Scientist, helping monitor one of Iceland’s lesser-known glaciers while soaking in stunning views and fiery highland wilderness.
What we love most about this tour is how it balances adventure, education, and environmental impact. You don’t just look at glaciers — you actively contribute to their understanding. However, the physical nature of the trek and the need for moderate fitness are worth considering for some travelers. This tour suits those who crave authentic, meaningful experiences in nature rather than just sightseeing from a distance.
If you’re eager to combine scenic driving, a rewarding hike, and a chance to make a difference, this tour is perfect. It’s ideal for travelers who enjoy hands-on activities, learning about glaciers, and exploring off-the-beaten-path Iceland.

Your day begins with a drive through the iconic Thorsmork Valley, often called “Valley of Thor” because of its mythic landscape and Viking-like grandeur. The journey alone is worth the price, with rugged terrain, glacier-fed rivers, and striking colors that vary with the weather. The 4×4 transport ensures comfort over rough tracks, and the guides are seasoned storytellers, often sharing local legends as they navigate.
Many reviewers highlight the thrill of this drive. One noted, “The landscape is constantly changing — from mossy hills to jagged peaks — and you’ll love the way the scenery makes you feel small in the best possible way.” The highland scenery sets a dramatic backdrop for everything that follows.

Next, you’ll gear up for a moderate trek through a hidden canyon — a route far away from tourist crowds and well away from the busy trails. This part of the adventure typically lasts about 1-1.5 hours each way, so good footwear and physical fitness are important. The canyon’s beauty lies in its seclusion and natural untouched state. You’ll navigate around rocks, river crossings, and lush greenery that contrasts with the icy landscape ahead.
One guide remarked that “the canyon feels like a secret, a true wilderness experience,” which gives you a sense of discovery and adventure. The highlight, of course, is arriving at the edge of Krossárjökull Glacier itself — a sprawling, dramatic sheet of ice that feels untouched and alive.

Once at the glacier, the real magic begins. You’ll get a safety briefing and equipment training to ensure everyone can participate in the mapping activity safely. The guides are experts and enthusiasts, eager to share their knowledge about the glacier’s natural features and ongoing changes.
From “surreal dead ice formations to the mesmerizing depths of glacial features,” the glacier offers plenty of photo-worthy moments. Several reviewers mention the “natural beauty of the glacier” and how it’s less visited compared to more popular spots, giving a sense of exclusivity.

Here’s where this tour stands out: you become a Citizen Scientist. Equipped with glacier mapping tools, you’ll help document the terrain, contributing data that is used for ongoing climate studies. The guide explains how this information helps monitor the glacier’s health, history, and the broader climate picture.
Participants report that “being part of something meaningful makes the experience more rewarding,” and receiving the study results and ongoing updates after your trip adds a personal touch. The Certified Citizen Scientist certificate from Katla Geopark is a memorable takeaway, symbolizing your contribution to environmental research.
A packed lunch is served amidst jaw-dropping scenery, which many describe as the perfect way to relax and absorb the surroundings. Imagine biting into Icelandic sausage or a sandwich while gazing at vast ice fields — it’s a moment of true wilderness indulgence. The guides often share stories about the glacier’s history and its role within the Katla Geopark, making the meal both delicious and educational.

This tour is not just about the scenery; it’s about participating actively in scientific monitoring. The guides are knowledgeable and passionate, and their explanations help connect natural features with broader environmental issues. Reviewers consistently praise the guides, mentioning their “expertise and enthusiasm,” which elevates the experience beyond just sightseeing.
However, it’s worth noting that moderate physical activity is involved. The hike’s length and terrain may not suit everyone, especially those with mobility issues or unprepared for outdoor exertion. Also, since it’s a full-day activity, packing appropriate outdoor clothing, sturdy hiking shoes, and water is essential.

The tour begins at the N1 Gas Station in Hvolsvöllur, where you’ll meet your guide. The round-trip transportation in a comfortable 4×4 ensures a smooth ride through Iceland’s rugged highlands. The total duration is around 10 hours, including travel and the activities, so be prepared for a full day of adventure.
Pricing includes expert guidance, equipment, transportation, and the scientific certificate, which many see as good value considering the unique nature of the experience. Food and drinks aren’t included, so bringing your own packed lunch and water is necessary.
This is a fantastic choice for adventurous travelers who want to go beyond typical Iceland tours. It’s perfect if you love nature, hands-on activities, and making a tangible impact through scientific contribution. It suits those comfortable with moderate hiking and outdoor conditions. If your goal is to see Iceland’s glaciers but also to understand their changing nature and participate in climate solutions, this tour offers an unbeatable combination of fun and purpose.
On the flip side, travelers with mobility issues, small children, or those seeking a more relaxed sightseeing experience might find this tour too physically demanding or restrictive in terms of time and activity type.
The Krossárjökull Glacier Mapping Adventure offers a rare blend of exploration, learning, and contribution. You’ll enjoy breathtaking scenery, expert guidance, and the satisfying feeling of helping monitor a glacier that’s changing right before your eyes. It’s more than just a day out — it’s a meaningful way to connect with Iceland’s natural environment and participate in crucial climate research.
While it’s not the cheapest tour, the value lies in the authenticity, education, and unique experience you gain. If you’re a curious traveler who appreciates a bit of physical activity and genuine engagement with nature, this adventure will leave you inspired and informed.
