The road from Bombala to Orbost is one of the best rides in the country in my opinion.
Sweeping grand high plains road, a little bit of gravel then 105km of non stop corners down to Orbost. Bombala is a destination in itself, great history and affordable pubs and of course the major bike show of the country held there every year.
To the ride itself, the gravel is easy and then you have a mixed bag of road surface. If you have your suspension set compliant for aussie roads not the race track then you should not be bothered. I never even noticed it myself but have read sports bike riders saying it was bumpy.
High Australian country scenery is spectacular. A must ride road.
