Wonders of Nature. With its narrow entrance and steep mountain sides, the Trollfjord is really exotic and spectacular. The narrow mouth of the Trollfjord is only 100 meters wide, and widens to a maximum width of 800 meters. The steep mountains surrounding the fjord are between 600 and 1100 metres high. The incredibly steep mountain sides add to this amazing experience, and Sea eagles circling around the mountain peaks are quite a common sight.
