I enjoy hiking the Greenbelt Route, also a great biking path that is 475 km long.
"Ontario’s Greenbelt is the solution for fresh air, clean water, healthy local food, active outdoor recreation, and a thriving economy. At almost 2 million acres, it’s the world’s largest permanently protected greenbelt, keeping our farmlands, forests, wetlands safe and sustainable.The Friends of the Greenbelt Foundation works to help keep farmers successful, strengthen local economies, and protect and grow natural features."
