Yarker, Ontario

Napanee River, Ontario

Ontario, Canada

This test site is in the small community park and is approximately 100 meters above the Yarker bridge and Simcoe Falls ( which is a large 40+ foot vertical drop).

The water moves rapidly in this area throughout the year, and it can be dangerous to inexperienced swimmers, kayakers and canoeists.
