More ways to explore the area's outdoor wonders
A cool wind cuts across exposed quartzite as you climb—the rock underfoot ringing faintly with each step—until the forest thins and the world opens. The Crack in Killarney Provincial Park is a narrow cleft in the La Cloche ridge that forces you to root your feet on lichen-scoured granite, pull on hands for balance, and earn the view. From the summit you look back over deep blue lakes and pale ridgelines that push to the horizon.

The La Cloche ridges are ancient quartzite sculpted by glaciers; the park was protected in the mid-20th century to conserve its unique geology and coastal landscape.
Conservation
