Join the Katla Glacier Mapping Expedition from Vik, a full-day citizen science experience that combines glacier trekking, climate research, and stunning Icelandic scenery.


The Katla Glacier is a striking feature in Iceland’s southern highlands, and this expedition offers a rare chance to participate in real scientific research. Departing from Vik, the tour takes you into one of Iceland’s most dynamic ice landscapes, where the glacier’s rate of recession is actively mapped and monitored. The focus is on climate change impact, giving participants a meaningful understanding of how glaciers are changing over time.
This private experience caters to small groups of up to four people, ensuring personalized attention and detailed explanations. The 8-hour duration allows for an in-depth exploration, combining scenic driving, trekking, and scientific work. The tour is suitable for those with a sense of adventure, a basic level of physical fitness, and an interest in environmental science.

The day starts with a scenic drive from Vik in a private 4×4 vehicle, which is specially equipped to handle Iceland’s rugged highland roads. During this drive, the guide shares insights into the geological significance of the area and prepares you for the activities ahead.
Upon reaching the glacier, a comprehensive safety brief takes place, covering glacier hazards, safe paths, and proper use of the scientific equipment. The team provides specialized gear—including crampons, helmets, and ice axes—to ensure safety and facilitate effective data collection on the icy terrain.

Once equipped, the group treks along the bottom edges of the glacier, focusing on measuring its current recession. Using advanced GPS equipment, you will gather data on how far the glacier has moved and where its edges are retreating.
This process is integral to understanding climate change effects on glaciers worldwide. The guides explain glacier dynamics, sharing details about Katla’s history and how the current state of the glacier reflects environmental changes. By actively participating, you help contribute to ongoing research efforts.
Throughout the day, the guide shares insights into Katla’s volcanic and glacial history. You learn about how the glacier has receded over time and the impacts of climate change on its size and stability. These lessons are delivered in a way that combines scientific facts with engaging storytelling, making complex topics accessible.
The educational briefing ensures that each participant understands the importance of monitoring glaciers and how their contributions support scientific understanding and local preservation efforts.
