A.Y. Jackson Lake, named after the Group of Seven artist, is striking with its blue waters nestled against a backdrop of pink rock and green vegetation. This is a lovely scene to photograph or sketch. The Cranberry Bog Trail gives hikers an opportunity to see Killarney's beauty up close. In wet weather rock surfaces are very slippery. This trail allows excellent views south over the Bay, and exhibits typical Precambrian Shield geology.
Wildlife includes small mammals such as squirrels, mink and raccoons.
Vegetation is typical of the rocky, windswept terrain throughout Killarney and the Georgian Bay coast. Soils are acidic, and vegetation is stressed by shallow soil depths and harsh growing conditions. In some locations, protected areas provide enough soil to allow large pine, oak, maple and shrub species to gain a foothold. Black metal rings used for mooring lines during the logging days can still be seen at a few locations along the trail. Interpretive plaques on the route tell of the colourful history of this part of Georgian Bay.
