This hair-raising road should only be taken by experienced drivers who have nerves of steel. This rocky, road is about 100 miles long, with a 6-mile stretch that’s particularly hazardous; as it looks as if you could fall off the roadway at any moment. You must be very patient as well if you choose this route, it’s only wide enough for one jeep at a time to pass, and with no guardrails in sight, this dirt and gravel road is unstable in many parts.
The Highway road was built hundreds of years ago by locals and has not been maintained over the decades. One wrong move by a driver could send a vehicle down a vertical fall of 2,000 feet. This road is so frightening, that it’s even nerve wrecking to watch videos of people driving over it.
Trollstigen, Norway
Trollstigen, also known as “the Troll Ladder" by the locals, is an engineering masterpiece in the midst of blissful natural landscape, which is why it's become the country's most visited tourist road. It may seem like an absolute joy to drive along, but beware, its plague with 11 magnificent hairpin turns, each bend even has its own name.
If you ever take this road you'll notice that some of its parts are actually carved into the mountain itself and in other places, it built in stone. Historically, Trollstigen used to be an famous transport passage between the villages Valldal in Indre Sunnmøre and Åndalsnes in Romsdalen.
Cetinje - Kotor road, Montenegro
Located on the coast of Montenegro, Cetinje is an historic road connecting the old city, Kotor, with the small city Cetinje, from which you can enjoy the spectacular view of Kotor bay along the way. As beautiful as it sounds, this road is famous for being one of the most hairpinned roads in the world. This curvy and mountainous road rarely permits you to go over 18 mph (30km/h). The most infamous part of the road is the Kotor Serpentine, a short 5 mile (8.3km) stretch with 16 hairpin turns. Usually when travelers remark about the danger of the roads in Montenegro, they're often referring to Cetinje.
To make matters even more worrying, this road isn't in the best condition and requires strong nerves to negotiate it. Some days there are lanes for passing, but then other days, rock falls and get in the way, but at least there's the gorgeous coastal view, just don;t get too distracted, as often impatient local drivers make hunk at you to hurry it up. Enjoy, but be cautious.
Carretera Federal 1 (Highway 1), Mexico
Highway 1, stretches 1,063 miles (1,711 km), along the Baja California Peninsula, from Cabo San Lucas in the south to Tijuana in the north. While some parts of the road are paved with asphalt, most of its barriers offer little more than token protection, as a result, large stretches should be taken at a snail's pace. As there are many blind corners and drivers should always be alert for vehicles coming from the opposite direction.
Because of the lack of shoulders, road signs, and the fact that there are so many blind corners, accidents are common and, in many areas, you can see guardrails that are split open where previous drivers have missed their turns and met their doom.
Nairobi-Nakuru Highway, Kenya
The Nairobi-Nakuru highway's 99 mile (159 km) stretch is notorious for being the most dangerous road in the country. The got it's infamous reputation mainly because its local driver's. Speeding, poor overtaking skills, and drunk driving (which is pretty common to see), are common, and if that wasn't bad enough, there hardly any traffic law enforcement in sight. Those factors, along with pedestrians and animals wandering into the road makes this highway one dangerous place to be, in fact, in one year alone, 320 people were killed on it.
While defensive driving lessons could make this road a bit safer, it's still quite risky. It was recently repaved in effort to lessen road traffic accidents, but sadly this still hasn't helped much. At least the Kenyan Government has recently begun to crack down on drunk drivers which is a major part of the problems s well.
