Amalfi Coast Highway
The Amalfi Coast is truly gorgeous no matter what time of the year you visit. Its coastal route will show you great views of mountains and the water. The only catch is that it can be hard to navigate there.
Leh-Manali Highway
This is a very valuable road to the Indian Army. This road is well-maintained, but there are factors that make it dangerous too. For one thing, landslides are common. Many people get altitude sickness as well.
