I'm visiting Sydney in February 2013 with an 11 month old baby whose maximum limit in a car before cracking it will be about 2 hours or so. I plan to do a guided coach trip to the Blue Mountains but will rent a car to see the coastal areas north of Sydney. My question is - what areas do you think have the most beautiful natural scenery? At the moment I'm considering going as far as Port Stephens - would you recommend concentrating our sightseeing in PS or are there other places you think are more beautiful closer to Sydney? Thanks!
