Toronto has more ravines than any city its size has a right to. They cut through the grid like cracked glass — pockets of forest below the street level, sometimes only a block wide. You can walk most of them in under an hour and emerge somewhere unfamiliar.
These five are the ones I keep coming back to. None of them is a destination on its own; they're the kind of place you slot into a morning. Each entry below has the route — tap any one to open it in Foray if you've got the app, or just read it as a map.
Trail data sketched from public OpenStreetMap traces. The polylines on this page approximate the actual routes — your Foray app will resolve precise geometry when you tap into a trail. Got a correction? sundaylabs.app@gmail.com.
