Exploring Krossárjökull: An Adventure That Combines Nature and Science
Iceland’s wild landscapes are full of surprises, and one of the most intriguing experiences you can have here is the Krossárjökull Glacier Mapping Adventure offered by Gravel Travel. This full-day excursion pushes beyond the usual tourist spots, taking you into the heart of the Icelandic highlands to explore a largely unmonitored glacier. It’s not just sightseeing — you get to become a Citizen Scientist, helping track the glacier’s changes while soaking in some of Iceland’s most stunning scenery.
What I really appreciate about this tour is how it combines adventure with meaningful contribution. You’ll drive through the eye-catching terrain of Thorsmork, with its vibrant colors and glacier-fed rivers, and then hike into a serene canyon away from the crowds. The guide, often a knowledgeable local, explains the glacier’s history and its crucial role within Katla Geopark, making the experience both educational and awe-inspiring.
One thing to keep in mind is that this experience is quite active. The moderate hike, lasting about 1 to 1.5 hours each way, is suitable for fit travelers but might be a stretch for those with mobility issues or very young children. Also, since weather can be unpredictable, proper outdoor clothing and comfortable shoes are essential. Overall, I find the combination of scenic drives, a rewarding trek, and the chance to be part of climate monitoring makes this a worthwhile choice — if you’re prepared for a day in nature’s more rugged corners.

Discovering Iceland’s Hidden Glacial Treasure

Iceland’s landscapes are familiar to many travelers, but few experiences let you go behind the scenes of glacier monitoring like this. The journey begins with a scenic drive from Hvolsvöllur, taking you through Thorsmork, a place legendary among hikers and nature lovers. The scenery is breathtaking — vivid ridges, glacier-fed rivers, and volcanic formations that seem almost surreal. You’ll get helpful tips from your guide, such as how to spot the telltale signs of glacier retreat or how the landscape is shaped by volcanic activity.
Driving through Thorsmork is a highlight itself. The 4×4 transportation over rugged terrain is a chance to soak in some of Iceland’s most iconic highland views. As you cross river crossings and gape at glacier-fed streams, it’s easy to feel like you’ve stepped into a different world. The guide, often an expert in local geology, shares fascinating tidbits about the landscape’s formation, making the journey as educational as it is visually stunning.
Once you arrive at the canyon, the real adventure begins. The hike, carefully guided and designed to be moderate, takes you into a quiet, less-frequented part of the highlands. The canyon’s walls and natural formations set a dramatic stage. Here, you’ll gear up with equipment and learn how to map the glacier’s surface – a task that’s both fun and impactful. The guide explains how this information helps scientists monitor glacier health and climate change, giving your effort real-world significance.

The Trek to Krossárjökull Glacier
The walk to Krossárjökull is one of the most memorable parts of the day. The trail winds through a pristine landscape, untouched by mass tourism. As I’ve read in reviews, “This offbeat canyon feels like a secret corridor into Iceland’s wilderness,” and that’s exactly how it feels. The glacier itself, often characterized by “dead ice formations” and mesmerizing crevasse patterns, offers a stark, almost otherworldly beauty.
The guide’s explanations about the glacier’s features—such as the phenomenon of “dead ice” or the glacier’s role within Katla Geopark—lend context and depth to the visual spectacle. You’ll be amazed at the natural sculptures made of ice, some of which look like frozen sculptures carved by time and elements, and others that look like relics from a different era.
Mapping the Glacier: Combining Science and Sightseeing
One of the most unique aspects of this experience is the opportunity to participate in glacier mapping. Equipped with specialized equipment, you get a crash course from the guide — often a trained Citizen Scientist — in how to collect data about the glacier’s surface. Your contributions, along with those of the group, are used to monitor the glacier’s health and inform future research.
This hands-on involvement turns what might be a simple sightseeing trip into a meaningful scientific contribution. You receive a Citizen Scientist Certificate from Katla Geopark, and the results of your efforts are emailed to you, making the experience both tangible and gratifying – you helped track the glacier’s story.
Lunch with a View
After the trek and mapping, a well-deserved packed lunch is served in a location with jaw-dropping views of the glacier and surrounding mountains. It’s a simple but memorable moment — enjoying good food while marveling at the natural beauty that surrounds you. Your guide will share insights into the glacier’s history, connecting the landscape with climate dynamics that affect Iceland and the wider world.
