When looked from above, the Trollstigen Road looks like a child’s scribbles but it’s an actual road. The locals actually call it “the Troll Ladder. The road has an abundance of sheer drops and hairpin bends and it’s even more dangerous in the winter when large parts of the road get frozen.
Le Passage du Gois, France
Le Passage du Gois is so dangerous that the authorities open it only for a few hours every day. For the rest of the day, this road is under water. Yes, you read that correctly. The passage connects the island Île de Noirmoutier with the mainland and it doesn’t have any barriers to protect the drivers because the road is under water most of the time anyway.
