Limehouse Conservation Area in Halton Hills

From experiencing the natural wonders of the Niagara Escarpment to learning more about the cultural heritage of its past, Limehouse Conservation Area offers a unique experience for adventurers. At its heart lies a geological area known as the “Hole in the Wall”, where ladders cut through fissures in the escarpment rock. 

There are 5 trails of moderate difficulty: Kiln Trail (0.05 km), CVC Trail (0.9 km), Bruce Trail (1.9 km), Black Creek Side Trail (1.5 km) and the Access Trail (0.2 km). 

What we did:

We stayed on the Bruce Trail (take at a left when you reach the fork at the beginning of the trail) and made it to the "Hole in the Wall," bridge as well as the Lime Kilns and Mills Ruins. 

The "Hole in the Wall" was an unexpected pleasant surprise for us. We didn't realize how much fun it was would be to climb down the ladder into the fissure and climb around. You can spend a chuck of time exploring the area and seeing where each fissure leads you. 

Continuing past the fissure on the Bruce Trail, you'll reach the river where you can cross the bridge over Black Creek. It's definitely a photo-worthy bridge. But be careful when you cross it! 

On the other side of the bridge, continue on the trail and you'll find the Lime Kilns and Mills Ruin.
