Bruce’s Caves make up a stretch of the Niagara Escarpment carved out by waves 7,000 years ago. Walk the 2.9-kilometre path to view the caves, or go farther on the Bruce Trail, an 840-kilometre route with stunning views of the escarpment and forest. Stop at the picnic shelter for lunch and a bathroom break before heading out into the wilderness—just keep dogs on leash. Snag a day parking pass ahead of time to jump into the fun.
