LM26: The company we used was OzTrails for both the Blue Mountains & the Hunter Valley. The guy (Mouse) who did the Blue Mountains tour was a scream & I forget the other guys name,but he was really good too. Hope this helps. By the way in Darling Harbour on Saturday nights they have a fireworks display between 9 & 9.15 pm which is just brilliant, well worth a wander down if you like that kind of thing. When you go to Hamilton Island, ask about a visit to WhiteHaven beach it's just stunning!
