Underground Exploring

All you need is a flashlight or headlamp, sturdy hiking shoes and a curious mind to explore the underground jungle gym of the Bruce County caves and caverns.

Formed thousands of years ago by receding glacier melt waters, the caves covering the Niagara Escarpment on the Bruce Peninsula give a brief introduction to our ancient world. Investigate closely and you’ll discover fantastic fossils, plus the beginnings of stone icicles called stalactites dotting the cave ceilings!

The Grotto at the Bruce Peninsula National Park

Of the 7 kilometres of karst caves (meaning: created by wave action) along the park’s shoreline, the Grotto at the Bruce Peninsula National Park is the largest and most outstanding, not to mention one of the most popular. It is a bottomless pit, cupping the turquoise sun-bright water of Georgian Bay, inviting a refreshing swim on a calm summer day. Park fees do apply. For the ultimate experience, it’s best to visit in the Spring and Fall.

Greig’s Caves

The Greig's Caves are a natural attraction boasting to be “Ontario’s Largest Natural Limestone Caves,” presents 12 caves and tunnels linked by a one kilometre-long trail. The 1980’s classic movie “Quest For Fire” and 2013’s family movie “Against the Wild” were filmed here. Admission fees do apply but its worth it!

Flowerpot Island

The Flowerpot Island 3-kilometre trail leads from the landing dock to the infamous “flowerpot” rock formations, looping back past some pretty monumental caves. A set of stairs leads up to the jaws of one, while interpretive signs describe their formation. It is accessible only by boat and park fees do apply.

Bruce’s Caves

Former home to Wiarton’s very own hermit, Robert Bruce, the Bruce Caves conservation area features a massive “undercut” cave with an impressive crevasse at its back and a substantial pillar at its front. Exploring the inside calls for poise and grace, as you tread on rock rubble that has collapsed from the ceiling.
