Hi Bennyboy. As Mike mentioned above, he and I did a trip through the Vic desert parks last October. Was really great; amazing variety of scenery, landscapes, and riding…and pushing.
I’d say about 90% of the route was rideable, with some sections of pushing through heavy sand. The longest stretches of sand-pushing were along Mopoke Track to Mopoke Hut in Murray-Sunset (about 9kms from memory), most of the route through Annuello Reserve (this was quickly forgotten after I saw two Malleefowl, which I had hoped to see), the Freeway Track north through Wyperfeld (shorter, but still heavy going) and some smaller sections elsewhere. Most of them were manageable; you kinda just get into a rhythm of ride a bit, get off and push a bit, repeat.
The main tracks we went along in Hattah-Kulkyne were mostly rideable, though our original plan of doing a loop a north and coming back down the Murray River was part-thwarted because of the heavy flooding only weeks before. I think we did Mournpall Track, Eagles Nest Track, Bitterang Track from memory. The Hattah Lakes are absolutely beautiful and well worth your while to have a look around. Camping at Lake Mournpall is tops.
I can’t recommend the whole Mallee area enough; it is one of the true desolate and beautiful places in the state.
Here’s a link to the route we took, with some slight alterations - we didn’t come back down the Murray track, as I mentioned above, and didn’t head from Manangatang to Lake Tyrell, but instead went on a more south-easterly line to Chillingollah and then to Swan Hill.
If you need any other info, I’ll try to help you out where I can.
