While much of Grundy Lake Provincial Park is designated as a 'Natural Environment Park', with a focus on both recreation and ecosystem protection, the area around Swan Lake has been declared a nature reserve and serves to protect fragile ecosystems and biodiversity. https://www.ontario.ca/page/grundy-lake-provincial-park-management-plan (Visited June 8, 2026)

Kidney Lake is a small body of water that drains into Kakakise Lake to the south at high water levels. The Crack Trail passes nearby the lake; however, it is not accessible and is not visible due to the dense forest. Only when you stand at the top of The Crack and look back can you clearly see Kidney Lake. (Visited June 7, 2026)

The Kakakise Lake is an approximately 4-kilometer-long lake in the La Cloche Mountain Range at an altitude of about 200 meters. The name Kakakise Lake comes from the indigenous Anishinaabe/Ojibwe language and means, in translation: mischievous old crow. The Crack Trail crosses the outflow of Kakakise Lake on a wooden boardwalk, which was built over a beaver dam. The dam, together with the boardwalk, dams up the lake to such an extent that only a "trickle" flows through, leaving the streambed of Kakakise Creek more or less dry. The water flows west through Freeland Lake and George Lake, eventually flowing into Georgian Bay as the Chikanishing River. (Visit on June 7, 2026)

The view from The Crack, a white quartzite rock, is stunningly beautiful. The scenery stretches across the La Cloche Mountain Range and several lakes, to the west the crystal-blue Killarney Lake in the foreground and O.S.A. Lake in the background, and in the distance to the south, Georgian Bay in Lake Huron. By the way, O.S.A. stands for Ontario Society of Artists; Trout Lake was renamed in 1933 to honor the group for their conservation efforts. To the east and south, dense forests stretch out with maple trees, birches, and conifers. The narrow Kakakise Lake cannot be seen from The Crack. (Visit on June 7, 2026)

On the last few meters of altitude, the path runs steeply uphill through the gorge between two massive quartzite rocks. You climb upwards over large, angular rocks; this should pose no problem for experienced hikers. (Visit on June 7, 2026)

Before the final ascent to The Crack, the route leads with a slight incline over a rock plateau with partially smoothly polished quartzite rock. To avoid going off the route, you should pay particular attention to the trail markers, blue wooden stakes. Stone men are probably well-intentioned, but not always helpful.

The Crack Trailhead is located on Highway ON-637 in the south of Killarney Provincial Park. The parking lot offers space for several cars and small campervans. Two information boards provide information about the trail and explain the code of conduct. From the trailhead, a wide path leads through the shady forest with mostly young maple and birch trees to the outlet of Kakakise Lake. (Visit on June 7, 2026)

Swan Lake Trail takes visitors on a loop around Swan Lake through forests, marshland and over glacier-scoured granite boulders. Mid-July through early September is blueberry season, and there are tons of plants that will bear fruit along this trail. In warm summer months, some visitors will also swim in swan Lake, using the granite boulders as a sort of beach.
