Adelaide is an unusually easy city to do with children. Almost everything a visitor wants sits in or beside the park lands, a flat green belt that rings the city centre, so you can walk between the zoo, the museum, the gardens and four separate playgrounds without ever getting back in the car. That matters more than any single attraction.
This guide is organised the way a day with kids actually goes rather than by category: one big thing in the morning, somewhere to run at lunch, and something indoors held in reserve for when the weather or the mood turns.
Start with one big thing
Pick one ticketed attraction a day and no more. Adelaide Zoo is the easiest first choice: it is genuinely small, which sounds like a criticism and is actually the point, because you can see all of it before small legs give out. The South Australian Museum is free, indoors and two minutes away on North Terrace, so it works as the backup when the weather turns. Cleland is the one where the kangaroos are not behind glass, but it is up in the hills and deserves a whole day on its own.
The city is ringed by playgrounds, and they are better than they have any right to be. Bonython Park has two 25 metre flying foxes and a water play zone; the Glover and Princess Elizabeth playspaces sit on the south and east sides within a short walk of each other. Entry is free everywhere and most have toilets on site, which is the thing you will care about by mid-afternoon.
Adelaide summers hit the high thirties and the rain, when it comes, commits. An indoor play centre is the difference between a salvaged afternoon and a bad one, and they are scattered right across the suburbs so there is usually one near wherever you are staying.
South Australians take coffee seriously and the cafes here know what a pram is. These ones either have a play area, sit beside a playground, or both, so you get a hot drink that stays hot.
Yes, and particularly for younger children. The city centre is flat, compact and ringed by free park land playgrounds, and the zoo, museum, art gallery and botanic garden are all within a short walk of each other on and around North Terrace. You can do a full day without driving.
What can you do in Adelaide with kids for free?
A great deal. The South Australian Museum, the Art Gallery and the Adelaide Botanic Garden are free to enter, and every park lands playground is free, including the big ones at Bonython Park and the Glover and Princess Elizabeth playspaces.
How many days do you need in Adelaide with children?
Three is comfortable. One for the city itself, one for the Adelaide Hills including Cleland Wildlife Park and Hahndorf, and one for the beach at Glenelg or Henley. A fourth lets you add Monarto Safari Park, which is about an hour east and needs most of a day.
What is the best time of year to visit Adelaide with kids?
Spring and autumn. Summer regularly passes 35 degrees, which makes unshaded playgrounds unusable in the middle of the day, and school holiday attractions get busy. March to May and September to November are mild and far quieter.
