Adelaide is the capital city of South Australia, and stands on the shore of the Great Australian Bight. Visitors with a hire car in Adelaide can visit picturesque villages in the Adelaide Hills, like the historic German settlement of Hahndorf, and explore the world-class vineyards of the Clare and Barossa Valleys. Popular day-trips include the white beaches and rugged coast of the Fleurieu Peninsula or Holdfast Bay, with its dolphin-swimming beach and trendy beachfront cafes. Further afield, go hiking in the Flinders Ranges or take a ferry to meet the wildlife of Kangaroo Island where there are colonies of sea lions and penguins.
