Trolltunga, Hardangerfjord region in Norway. 10 hours hard hike to get there and back - bring hiking boots and be equipped for the high mountains. Trolltunga is about 1,100 meters (3,500 feet) above sea level and about 700 meters above the lake down in the valley. Folgefonna National Park and the glaciers in the background. Travel: Go to Bergen (BGO) - then a 3 hours drive to Odda. You can also climb to Trolltunga on a via ferrata with a guide from opplevodda.com. Photo by Stig Tronvold.
