Lake on the Mountain, ON

Sitting 60 metres above Lake Ontario Lake on the Mountain is a mystery. Its water comes from an invisible source and drains to Lake Ontario down below. This is a stunning park with views of both lakes. You can take a plunge in the lake here but if you're looking for a place to spend the day at the beach the County offers better sandy beaches. The views from here are priceless. While Ontario Parks tests water quality at this beach every week the information available online is often outdated. Contact Ontario Parks for most up-to-date water quality results.
