For most Adelaide residents, a drive through the hills is a popular pastime, particularly due to proximity. With Adelaide being a linear city extending 90 kilometres (56 mi) north to south, the hills are within 20 kilometres (12 mi) of the majority of residents.

The first vines were planted in the Hills in 1839, three years after South Australia was declared a province, a case of that wine was
