Easy 30 minute drive. ENJOY.
Lovely area, Kim - I was up there a couple of weeks ago and there are lots of interesting places to visit.
Have eaten at Tonic several times & always enjoyed it.
Basalt (in the Commercial Hotel) is another good restaurant in Millthorpe.
Angulong WInes have a cellar door there, too.
Easy drive from Carcoar. Do have a look into the School of Arts Hall when you're there. Charming historical mural behind the stage and the hall is beautifully painted in period colours.
Might be an idea to book ahead; it's a popular district.
If you go up via Bells Line of Road, a couple of good spots for a coffee break or something more substantial are just outside Bilpin.
