Hold a koala at Cleland Wildlife Park. In the Adelaide Hills, Cleland lets you walk among kangaroos and emus and — unusually for Australia — book a supervised koala hold. Combine it with the Mount Lofty summit lookout next door for a view across the whole city to the sea.
Spend a day in the Barossa Valley. An hour north-east, the Barossa is home to famous names like Jacob's Creek and Seppeltsfield. Coach and small-group day tours with tastings and lunch run from about A$130–A$160 ($90–$110).
Ride the tram to Glenelg. Adelaide's beach suburb has a long jetty, calm swimming water and sunset views — the vintage-line tram from the city takes about 25 minutes.
Graze the Adelaide Central Market. More than 70 stalls of cheese, fruit, bakeries and multicultural food make this one of the southern hemisphere's best covered markets; it adjoins Chinatown, and several stalls are vegetarian-friendly.
Walk North Terrace, the city's cultural mile — the South Australian Museum, Art Gallery and Botanic Garden are all free. With an extra day, the German-founded village of Hahndorf in the Hills makes an easy half-day, and wildlife lovers can stretch to a full-day Kangaroo Island tour (long day; worth it for sea lions).
