Pinacanauan River is one of the largest tributaries of the Cagayan River, the longest and widest in the Philippines. Its name comes from the local term pinacanauan, which means “left-most.” It is found in the southeast of Cagayan Province in the municipality of Peñablanca in Cagayan Valley. Along with other rivers, it drains the agricultural plains of Cagayan Valley and serves as a water source for irrigation and other purposes. With its clear waters and beautiful natural setting, it is one of the tourist attractions in Cagayan province.
The tributary is found in the Callao Caves National Park in Peñablanca. A tourist zone, Callao Caves National Park features large rock formations and caves as well as Pinacanauan River. Wild lilies grow abundantly in this green area.
With its class I and II rapids, Pinacanauan River is a popular site for whitewater rafting and kayaking as well as for boating and swimming. The area around the river is surrounded by mountains which are suitable for hiking, climbing, and spelunking. Every year on April 21, a boat rowing race known as Bankarera takes place on the river.
