There are a number of excellent daytrips that you can do while being based in Adelaide. One of the best is a trip into the Adelaide Hills.
You really do need a car to be able to complete this trip but its certainly worth it. Chances are that if you are in Adelaide you are most likely to have a car anyway as its difficult to see the sights without one.
It's only a 20 minute drive from the centre of Adelaide and you are in Hahndorf.
Hahndorf was settled in 1839 by Prussian Lutheran migrants and you can see the German influence in the town today. During World War One Hahndorf was renamed Ambleside as most German names were renamed but later reverted to being called Hahndorf. You find much more German influence in South Australia than the rest of Australia.
It's a pleasant walk down the main street looking at Art Galleries and shops. It's a great place to get some coffee and German cake. Hahndorf was the home to South Australia's greatest artist Hans Heysen.

A short drive from Hahndorf is Bridgewater Mill. Bridgewater Mill is the home of the Bridgewater Mill Wines. The Adelaide Hills mainly produces white wines particularly Sauvignon Blanc. The mill also has a nice garden surrounds.

A short way up the road is Mount Lofty Botanical Gardens. The gardens have 2 entrances and I prefer the Piccadilly entrance (bottom entrance). The Gardens have wonderful walking trails and it is particularly scenic in March - May through Autumn. If you were to bring your own lunch this would be the perfect setting to have some sausage, cheese, bread and wine bought in Hahndorf during your daytrip. The gardens features cool climate plants not found elsewhere in South Australia and you could walk through the gardens for a couple of hours.
