Andalsnes Norway. Not far from the idyllic Andalsnes, you’ll locate a unique curiosity: the ‘Troll Wall’. It features immense grassy cliffs forming Europe’s highest vertical mountain face. An amazing natural wonder. A steady climb of the ‘Troll Ladder’ entails a zigzagging road of hairpin bends on the steep mountainside, revealing spectacular valley views as you near the thundering Stigfossen Waterfall.
