Warsaw Caves

Warsaw Caves is a group of limestone caverns near Warsaw, Ontario, known for long passages, small chambers, and unusual karst geology that makes them the area’s best-known natural attraction. Formed by fast-moving water acting on limestone deposited as the last ice age ended about 12,000 years ago, the caves were later left above water as flow diminished and the land rebounded after the ice melted. The Indian River also disappears underground through collapsed limestone channels nearby. Some smaller caves provide winter hibernation sites for bats. The surrounding conservation area, opened to the public in 1964, also offers trails, camping, swimming, canoeing, and notable limestone landscapes.
