There are 6 kilometers of Georgian Bay shoreline in Awenda. The Georgian Bay shoreline has a variety of energy and deposition beaches of boulder and loose sand. Where shorelines are exposed the driving north-west wind carries away lighter sand and leaves behind Awenda’s characteristic boulder shoreline. In areas with shelter from the prevailing wind lighter sand drops out of the water column to form the Park’s four sandy beaches. Dune complexes are not as well developed in Awenda due to the exposure of the shoreline to the north-west fetch. A number of plant species are found within these challenging environments. Many are endemic (found in no other location) to the Great Lakes.
