Lake Sampaloc is a volcanic crater lake in Laguna on the island of Luzon. It is the largest of the Seven Lakes of San Pablo. Nearly half of the lake's depth has a shallow depression at the bottom, indicating its volcanic origin. The lake is behind San Pablo city hall and is dotted with fishpens and small cottages built on stilts.
