Passing through the Gudbrandsjuvet observation deck, the altitude is getting higher and higher, the green in the field of view is getting less and less, the white is getting more and more, and the sight is getting more and more confused. At the end of May, the snow wall on both sides of the road was higher than the car, and the hole in the snow wall was actually blue, which was beautiful. Under the fog, visibility is less than 50 meters, a white, and the camera can't focus automatically. I'm really worried about suddenly jumping out of a elf! The sign "Mountain demon and dog can't enter" on the store door on the top of the mountain, so interesting! The Elf Road, Norwegian Trollstigen, English Trolls'' Path, Norwegian name means "Elf ladder". It is one of the most beautiful and spectacular roads in Norway and one of the most popular attractions for tourists. It connects the village of Valdal and the town of Ondarsnes ndalsnes and is part of Highway 63. The thrill of this road is not only the steep slope of 10 [%], but also the steep slope of 11 consecutive haircuts! The Elf Road was officially completed on July 31, 1936, under the auspices of King Haakon VII, for eight years. The reason why it took so long is because the winter weather conditions here are too bad to continue construction. Even today, the road must be closed every late autumn to mid-to-late May to ensure safety. Because natural disasters such as falling rocks and avalanches occur, The Elf Road has been repaired in large and small since it was built, and in the summer of 2005, it cost NOK 16 million to prevent falling rocks and ensure safe passage. On June 16, 2012, Trollstigen officially became part of the national landscape road. The summit has a 858-meter-high Stigrera observation deck designed by Reiulf Ramstad architects, with dynamic water as a concept, snow melting as a process of flowing water as a dynamic element, comparing the rock depiction of static elements and emphasizing the natural space and hierarchy, dynamic and static combination, and contrasting with each other. Unfortunately, when we arrived, the fog was thick, and all the buildings were in a white space, half covered. The cafe in the lounge area was not open.
