The Negros Occidental Eco-Tourism Highway, officially known as the Bacolod–San Carlos Road and Bacolod–Murcia–Don Salvador Benedicto–San Carlos Road, is an 81.12-kilometer (50.41 mi) scenic highway that connects the city of Bacolod[1] to the city of San Carlos in Negros Occidental, Philippines.[2] It cuts through the north-central Negros Island and traverses the Northern Negros Natural Park, north of Mount Kanlaon. Its western segment in Bacolod also known as Alijis Road (Romeo G. Guanzon Avenue)[3] has a two-way bicycle lane.
The highway originated from an old road connecting Bacolod to the foot of Mount Kanlaon in Murcia that is also historically part of Highway 336. It was later extended to San Carlos sometime after World War II.[4]
