All Killarney's hiking trails cover uneven and rocky terrain. Sturdy footwear is recommended.

Chikanishing Trail 3 km (1.5 hours) moderate
Winding to the park's southern boundary, this trail crosses a series of small ridges and ends at a wave-washed point on Georgian Bay. Vegetation is typical of the rocky, windswept terrain of Georgian Bay, though taller pine and oak have flourished in wind-sheltered spots where soil has accumulated. Old iron rings used for mooring lines during logging days can still be seen along the trail. Interpretive plaques tell the colourful history of this part of Georgian Bay.

Cranberry Bog Trail 4 km (2.5 hours) moderate
This trail passes some of the park's loveliest scenery. Bogs, marshes and swamps are home to sundew, leatherleaf, pitcher plant and cranberry. Beaver feed piles can be seen along the way. Many birds frequent this trail's habitats and Blanding's turtles make an occasional appearance in Cranberry Bog. Look for evidence of glaciation -- smooth rock surfaces, striations and chatter marks.

Granite Ridge Trail 2 km (1 hour) easy
This trail provides views of the unique La Cloche Mountains for which Killarney is renowned. It winds through old fields and forests and climbs to a ridge with two lookouts over the park. To the south, your eye moves along the shore from Collin's Inlet and Philip Edward Island to the expanse of Georgian Bay. To the north, see the spectacular La Cloche Mountains.

La Cloche Silhouette Trail 100 km loop (7-10 days) strenuous
Although this trail takes up to 10 days to do in its entirety, hikers can take shorter hikes starting from two trailheads in George Lake Campground. (Day hikers should leave sufficient time to retrace their steps along the trail back to the campground.)

The west section of this trail is moderate, heading to Acid and Lumsden lakes over rolling forested hills. It crosses small streams and rivers, occasionally following the rocky shores of small lakes. Keep on the lookout for wildlife, or clues of their presence.

The east section of this trail heads uphill to the Crack, a ridge with a vista of rugged and scenic landscapes. Considered strenuous, this section passes through forests and wetlands and over rocky ridges. It takes 12 hours of steady hiking and you have to climb over large boulders to reach the top of the ridge. Do not try to reach the Crack unless you are in good shape and can get an early start.
