We did the drive today with 2 4WDs. Excellent weather today and most of the days before, so dry and dusty tracks. The track is essentially more an unpaved road and accessible for almost any car with some bottom clearance. What we liked were the excellent picnic- and BBQ spots along the road ( I recommend Basin and Muirs
Lookout). What we did not like was the few
views along the way. From start to finish you drive over ridges, but all with tress on both sides, blocking an otherwise great view and trip. WOuld we do it again? Not for the drive, but we might come back for the camping locations.
BTW, we used the book "4WD
Treks Close to Sydney". We found the book to be accurate and very useful.
