Candaba Swamp Facts are essential for any parent or learner wanting to understand the rich biodiversity of the Philippines. The Candaba Swamp, also known as Candaba Marsh or “Pinac,” is one of the most important wetlands in the country. Located in the provinces of Pampanga and Bulacan in Central Luzon, about 60 km northeast of Manila, this vast floodplain is a critical natural flood retention basin and a haven for wildlife.
I want to share these Candaba Swamp Facts in a “Real-Talk” way. This area is not just a bunch of water; it is a living ecosystem that supports thousands of migratory birds and local livelihoods.

1. Location and Size of the Marshlands
Candaba Swamp lies near the towns of Candaba, San Miguel, and San Ildefonso. It spans approximately 32,000 hectares during the wet season, shrinking to about 10,000 hectares in the dry season.

It sits at a low elevation of about 11 meters above sea level, making it the lowest point in Central Luzon. The swamp receives overflow from several rivers, eventually draining into the Pampanga River.
2. Historical Background of the Pinac
Historically, Candaba Swamp was part of a larger chain of lakes in Central Luzon. Over time, silting from river networks caused many to shrink. The area has long supported families through fishing and farming.
