What is the Rouge Valley near Markham known for?

The Rouge Valley near Markham is known for the Rouge River winding through the suburban landscape just east of Markham and making its way down to Lake Ontario. A large area has been designated as Rouge National Urban Park, which is free to enter (unlike other national parks) and has lots of hiking trails and forest to explore. The park contains Toronto’s only public campground, the Glen Rouge Campground near Highway 401. The park also borders the Toronto Zoo, which makes the campground a great place for a family stay.
