I love the Clare Valley, only about an hour and a half from the CBD and the wineries are closer together than in the BArossa.

Chaff mill village in Clare is really nice, you can get 2 room self contained units. They have a beautiful big spa too .

In Adelaide - HAigh's chocolate factory tour, on greenhill road. You need to book but is free. Isn't huge but still good and you get samples.

Hanhndorf - german village, nice drive, yummy food and you can go to melba's chocolate factory on the way and Beerenberg jam factory in HAhndorf. I think they have an baby animal farm? Not sure.

Adelaide zoo if you have the kids, but it depends where you are from. If you have a zoo at home you may not want to take the time.

Gumeracha in the adelaide hills - AHs the big rocking horse. Also a toy shop. Ncie drive. I am sure you can get from gumeracha to hahndorf in the one trip just not sure how. I suffer from geographical embarrassment.

Google some of these things. I hope you find what you are after
