Riding the Barossa

Hi, I'm planning a trip to the Barossa Valley, with the Yetti of course, and was wondering if anyone had inside information on trail rides in the area. I'll be hiring a camper van, so mobility won't be a problem. I'll be looking for cross country tracks so a mixture of single track and dirt roads would be the norm I guess, I am an experienced rider with about 7 years under the belt but not looking for anything too narly… I'm looking to go within the next two months. I've done a few searches online but haven't come across much recent information on the area, most of the info seems to back date to 2010 or older.

Your help will definitely be appreciated!
