Welcome Andrew to the forum
Unfortunately we haven't stayed in the Hunter Valley yet but if you like wine tasting we love Mudgee!!!
We go every year for the Day on the Green concert and go early on the Friday so we see a little bit more of Mudgee each year.....Lovely place.
We always stay at the Riverside Caravan Park and the owners there are just great.... It is a lovely park and while it is in the middle of town the park backs onto the river and the camping spots up the back and next to the camp kitchen are lovely shady & grassy sites near the river.
Sorry I couldn't be more help but am interested in hearing how you get on. If you find one that is really good please let us all know here!!!!!
