Hunter Valley is a must. We hired bikes as well (tandems!!!) - the roads are pretty rough but a great laugh. Watch out for the magpies during the breeding season thoug - they'll swoop out of the tree at you.

Buggers! Also, get when you are on the bike, get the tasting sheets from the vineyard and mark up all the wines you want. THen before you leave take the car and pick up all the ones you liked!
