Kennon Road is a very scenic highway located in northern Luzon island of the Philippines. The roadway, with a length of 41.2 km (25.6 mi), links the mountain city of Baguio, at an elevation of 5,500 feet (1,700 m) above the sea level, and the lowland town of Rosario in La Union province.
The construction of this asphalted road started in 1903 and opened for travel on 1905. There are plans to declare the highway a national heritage park, to preserve it for posterity in recognition of its being part in the nation's historical and cultural heritage. Kennon Road is one of the most hazardous roads in the country especially during the rainy seasons when most of the road accidents occur. The road is prone to closure due to landslides, particularly during heavy rains or during typhoon conditions
The drive is definitely worth it. For travelers coming from Manila or the provinces in the central plains of Luzon it is the shortest route to Baguio. There is a need to be extra cautious when driving through the road since you will encounter sharp hairpin turns and blind curves. Also, guardrails are either missing along some portions of the road or are not strong enough to stop a wayward vehicle from falling into a deep ravine just beside it.
In addition to all these, on certain months of the year the late afternoon fog causes poor and limited visibility along the roadway. Travel time is frequently very long because of poor road conditions. It usually takes an experienced commuter from 45 minutes to an hour to negotiate the 41.2-kilometre (25.6 mi) steep and winding climb by car.
