The Torghatten mountain walk, located in Brønnøysund in Norway, is a great outdoor activity for adventure seekers. This easy hike takes only 15-20 minutes, but leads to an impressive 160 m long, 35 m high and 15 m wide hole through the Torghatten mountain. The landscape surrounding the hole adds to its beauty and awe-inspiring motion. Geologists and legends have alternate theories for how this structure came to be. Hikers can also take trails that go around or over the mountain, allowing them to experience the rugged nature of the area. It's a must-see spot, for both locals and visitors alike.
