If you’re thinking about adding something truly unique to your Iceland trip, the Sandfellsjökull Glacier Mapping Expedition from Gravel Travel offers just that. It’s not your standard tour—this is a chance to become part of scientific research, contribute to climate understanding, and witness some of Iceland’s most breathtaking scenery all in one go. While it’s a full-day commitment, the blend of adventure and learning makes it a standout experience for those who want more than just sightseeing.
What really draws us in about this expedition are two things: first, the opportunity to actually contribute to climate research by mapping a glacier—something you rarely find in typical tours. Second, the chance to gain a Citizen Scientist Certificate from Katla Geopark, which adds a meaningful, educational layer to your trip. A potential consideration is the physical aspect of the tour; it’s moderate in difficulty and requires good fitness, so it’s not suitable for everyone, especially young children or those with mobility issues. It’s best suited for travelers who are eager to combine adventure with a sense of purpose and have a genuine interest in nature and science.

What You Can Expect from the Tour

This is not your average glacier hike. The Sandfellsjökull Glacier Mapping Expedition is built around the idea of combining scientific contribution with adventure, making it quite unique among Iceland tours. It begins with a round-trip 4×4 transfer from Hvolsvöllur, a small town that acts as a convenient starting point in South Iceland. Once at the glacier, you’ll meet your expert local guide who will lead your group and provide specialized Citizen Scientist training.
The core activity involves mapping the glacier—a task that’s both engaging and meaningful. You’ll be equipped with glacier and mapping tools, and trained on how to use them effectively. This is where the “learning” really kicks in. Instead of just taking photos or admiring views, you will help document the glacier’s features, changes, and possibly contribute to ongoing climate research. The experience isn’t just about what you see; it’s about what you do.
