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 is the second part of photos from this walk:
These railway tracks are very busy on weekdays but no trains went by during my walk.
