Thinking Liliydale-Warby Rail trail plus as much of the O’shannesy Aqueduct trail as possible to get out to the Yarra Reservoir Camp Ground (only $6 + free showers!) with lunch in Warburton.
Then over to Marysville for lunch 2nd day then back along paved roads to Lilydale.
It was a good ride - flaked out of going over Marysville due to the weather forecast and laziness.
Shakes, the Aqueduct trail is sweet from Don road though there are steps you gotta hauls you bike up. I started the Aqueduct trail form the Healesville-Koo Wee Rp road entrance but there are sections that I found unrideably steep and loose. From Warburton its great and you can continue along it passed the ‘official’ end at Concrete Creek road to a logging road that take you down to the Warburton/Woods point road, don’t try Road ‘13’ or ‘1’ - see the pics below.
Upper Yarra Reservoir Camp is even better than I remember - $6.40 a night. Hot showers - fire pits - microwave - boiling water - fridges and $3 ice!
