The eastern side of the Don River between Don Mills Road and Beechwood Drive has a concrete trail beside it and is much-used by cyclists, joggers, dog walkers and hikers.
The western side however, has only a narrow dirt trail. During the 3 hours that I walked here in January, 2019, I saw 2 joggers, 1 mud-covered cyclist and 1 dog walker.
I started my southbound walk at the place where the West Don River meets the East Don River.
Here are some photos of the river and of the trail.
Here are some of the natural sights:
