The Crack
A quartzite cleft on the Killarney ridge with views over Killarney Lake, O.S.A. Lake, and distant Georgian Bay. It is the park's most popular day hike.
The Crack is a huge rock fissure in the Killarney ridge. The trail starts from a parking lot beside Highway 637 and runs about 6 to 7 km round trip, taking 3 to 4 hours. The first half follows gentle forest paths and wooden boardwalks. The final section requires scrambling hand over hand between boulders to pass through the fissure. At the top is an open plateau of white quartzite, overlooking the deep blue Killarney Lake, O.S.A. Lake, and the layered La Cloche ridges, with Georgian Bay visible on clear days. Autumn, when the hillsides turn red with maple leaves, is the most spectacular time. On summer weekends, the parking lot fills early, so arrive in the morning. Wear non-slip shoes and bring plenty of water, and do not attempt the climb in rain or when the rock is slippery. A park day pass is required.
