The Melbourne Baths were originally built to encourage swimmers not to swim in the Yarra River because of its pollution. The river was still a suspicious brown when I decided to mirror its course.
I walked a section of the Yarra River near Kew years back. My post on that hike: https://malleestanley.wordpress.com/2015/10/06/melbournes-yarra-bend/#more-3341
This time, I took the easy city route, passing restaurant after restaurant on the southern bank where tourist boats cruised back and forth.
