Five rivers worth knowing
Ilog Cagayan
Cagayan Valley · 505 km
Longest river in the Philippines. Drains the valley where Callao Cave holds the oldest human remains found on the archipelago.
Ilog Agusan
Caraga · 350 km
Its marshland is a Ramsar wetland and the heart of Manobo riverine civilisation.
Ilog Pampanga
Central Luzon · 240 km
Nursed Central Luzon's fishponds, rice fields, and the kapampangan table.
Ilog Mindanao
SOCCSKSARGEN / Davao · 373 km
Second longest. Fed the lowland and upland trade routes that stitched Mindanao together.
