 Three main access roads lead to the city of Baguio from the lowlands; Kennon Road, Aspiras-Palispis Highway (formerly Marcos Highway), and Naguilian Road (also known as Quirino Highway).Kennon Road starts from Rosario in La Union province, and winds through a narrow, steep valley.Although perilous and being prone to landslides during rainy season, it is the fastest route to Baguio from the lowlands, and offers a scenic view.
