3. Halsema Highway in Philippines
This highway is the highest highway in the Philippines in terms of altitude. The Halsema Highway is 150 miles long and connects the Baguio and Benguet provinces to Northern Luzon. Landslides, mudslides, and falling rocks are common along this road. Bus drivers travel at high speeds on these narrow roads, making it very dangerous for smaller vehicles.
A majority of the roads are unpaved with many steep drop-offs, some more than 1,000 feet. The lack of safety rails to protect drivers at high altitudes is one of the big reasons this highway is considered one of the most dangerous highways in the world. During the rainy seasons, it is almost impossible to drive along this highway because of the frequency of landslides.
