Known as ‘The Dark Fortress’ because of its unevenly pillared rock formations created due to volcanic eruptions. For Game of Thrones fans, it was used for the location of Mance Rayder’s wildling camp. These natural rock formations easily resemble dramatic sculptures that change slightly in color depending on the time of day and how the sun hits them. These volcanic formations can only be found here in Iceland and underwater in Mexico’s sea coast. #free #hiking #views #photography #climbing #camping
