Killarney offers a few different hiking options ranging from shorter day-use hiking trails to multi-day hiking trails. The most popular of these trails is The Crack (6km round trip, rated difficult). The trail overlaps with a small section of La Cloche Silhouette Trail (an 80km loop that typically takes between 7 to 10 days to complete) and weaves up the white cliffs of La Cloche Mountains and through a crack to the top of Killarney Ridge. The top of the ridge is reputed to provide the best views in the park.
Located on the crystal clear waters of Georgian Bay, Killarney Provincial Park is nestled in untamed wilderness, which include forests, mountains and wetlands. The landscape is so incredibly scenic that it inspired many members of Canada’s Group of Seven painters. It is also fitting that Killarney became a provincial park in large part because of the conservation efforts of these painters.
