7 Caves In Ontario You Can Explore If You Want To Feel Like Indiana Jones
Ancient underground worlds await.

Standing next to mossy limestone caves. Right: Exploring in the Bonnechere Caves.
If you enjoy the thrill of exploring ancient worlds and love a good adventure, there are a number of caves in Ontario waiting for you.
Most of the caves are limestone, created by conditions during the ice age. You'll forget you're in Canada as you climb through skinny cave spirals, walk through abandoned tunnels and admire blue water views from cliff edges.
As you might imagine, caves can be dark, uneven and slippery, so make sure you have sturdy shoes and a flashlight to be on the safe side. Prepare to cool off as you wander beneath the surface this summer.
