A hands-on, nature-focused adventure that takes you beneath the icy surface of Tindfjallajökull—one of Iceland’s lesser-known glaciers. This expedition with Katla Geopark offers a rare chance to see the tangible effects of climate change firsthand, all while actively participating in glacier mapping. What makes this journey particularly special is the combination of scientific contribution and wild Icelandic landscapes, far from the crowds at the more popular sites.
Two things I especially appreciate about this experience are the knowledgeable guides who explain the science in an accessible way, and the sense of contribution you get from helping document real glacial change. It’s a meaningful way to connect with the land and learn about climate issues directly in the field. However, keep in mind that the tour covers rugged terrain and involves a fair amount of physical activity, so it’s best suited for those in good shape. Also, the price reflects the personalized, educational aspect as well as the safety equipment and expert guidance.
