Walk the Petun Loop in early summer or fall. It’s a quiet trail and as you peer into the Black Ash Creek Valley, you can imagine the world of the Petun. You’ll also see the world of European settlers among the huge field stones cleared from fields. Along the corn fields you’ll see clusters of milkweed, a great spot to see monarch butterflies. Four kilometres south of Petun, the Bruce Trail reaches its highest point at 540 metres (1480 feet).

For years, the Petun nation lived in this area, with their longhouses and tobacco fields where open meadows now lie, their hunting grounds within the forest, their fishing and water source in the Black Ash Creek. Think about them as you look at the Black Ash Creek valley below this trail. This Conservation Area was named in their honour. An Iroquois speaking people noted for cultivating tobacco, the Petun were a smaller nation that lived along the slopes of the Niagara Escarpment.


Vistas of Georgian Bay, mixed forest, old limestone boulders, views of Osler Castle. Camping is also available south of the loop. Part of the Petun Side Trail awill be closed annually from December 1st through to March 31st, as noted on the map.
