World's Scariest Roads

Halsema Highway, Philippines

Location: Island of Luzon

Fear factor: Like many under-maintained mountain roads, landslides are a hazard on the Halsema Highway, where big stones and debris tumble from peaks. And along with the cloud forests comes mist that can ruin visibility. Tracing a circuitous path, this road crosses the massive Cordillera Central mountain range on the Island of Luzon, and many sections remain unpaved.
