Boulia to Mckinlay

Turn off at the Hamilton Pub will be quicker and shorter, but travelling up to the 9 Mile Bore and turning left through Mackunda will be the more scenic route. You'll pass through the Cawnpore hills, which are quite spectacular, and also up through the Toolebuc Gap, after passing Mackunda.

Bit over 30kms north of Toolebuc, you'll pass Cannington Mine on the left, and the road is then bitumen into McKinlay.

I did that road, McKinley down to the ruins of the old Hamilton Hotel in 92, it was a great track used by the station people and the mailman and was actually in better nick than the main road from Hamilton to Boulia
Great scenery and well off the beaten track.
Good luck and enjoy

Keep an eye in the road reports as quite a bit of flooding in the area at present. Not sure when you are looking to travel.
Enjoy.
