Surrounded by parkland almost three times the size of Manhattan’s Central Park, Adelaide is spread over 1.6 square kms (0.6 square mile) in a north-south, east-west grid of wide streets and four main squares. The main street, King William, runs from north to south through Victoria Square in the heart of the city. Some 29 parks are dotted within the central business district, and Australia’s most concentrated collection of department stores, boutiques, and specialty shops is located in Rundle Mall, home to more than 800 retailers. The city boasts in excess of 700 restaurants, cafes, and bars, with entire streets – such as Gouger and Rundle – evolving as “eat streets” of al fresco dining and international menus. Adelaide is renowned for its arts and theatre, and is the gateway to some of Australia’s most famous wine-growing regions. Free city-loop buses (“the Connector” and the solar-powered “Tindo”) visit the main tourist attractions.
