There are plenty of places to pull over and admire the view, so you don’t miss out on too much, It is called the Great Ocean road for a reason! There is actually so much to see and so many places to pull over and go for a walk or just stand and admire the view that you do not get a whole lot of driving done each day. It took us 4 days to go the Great Ocean road (from Melbourne to Adelaide) but we could have spent a lot longer doing it, I look back at it now and wish that we had more time to do it as 4 days seemed a little rushed.
The Great Ocean road is very well sign posted and markings are clear, there are plenty of signs marking upcoming tourist areas or points of interest and there was no shortage of signs reminding people that here in “Drive on the left in Australia”. Obviously the longer you take to do the road the easier the drive will be and if you have more than one driver this will also be an advantage. All in all its a very straight forward and simple drive however always make sure you are alert and careful of other drivers and hazards on the road and also make sure to take ever opportunity to pull over or you will miss all the natural beauty the Great Ocean road has to offer, I can only assume that is why you are driving the GOR to start with.
