This is a great weekend ride from Canberra. It's about 100km on each day, but it's reasonably flat. There's some highway riding on the Barton and Hume highways, but both have generally good shoulders, and most of the trip is on quieter roads. The main road from Binalong to Yass is a little undulating, as is the southern end of Dog Trap Road. Both Bendenine Stock Route (just labelled "Stock Route Road" on the signs I think) and Dog Trap Road are unsealed, but were in very good condition in winter 2007.
We stayed at the Old Royal Guesthouse and it was fantastic, although I think it's closed now (last checked in 2023).
