The snowy Frostfangs
Grundarfjörður, a small fishing village on the Snæfellsnes peninsula in Iceland, was used as a filming location for several scenes. The picturesque town was used to film scenes in the North of Westeros, specifically in the region known as the Frostfangs.
The most exciting scene filmed in Grundarfjörður was when Jon Snow, Ygritte, and the Wildlings cross the Frostfangs on their way to the Wall. This scene was filmed in and around Grundarfjörður due to the mountainous landscape, stunning fjords, glaciers, and snow-covered peaks, which perfectly matched the description of the Frostfangs in the books. The scenes of Jon and Ygritte walking through the snow-covered landscape and scaling the icy cliffs were some of the most memorable in the series.
