For something different in this city of culture and government, take a trip to the Bus Depot Markets. Every Sunday these markets operate in the old bus depot at Kingston, Canberra.
Travel by car (plenty of parking) or take a local bus, and allow yourself plenty of time to browse among the myriad of stallholder's wares.
Locally grown and produced organic foods, art and craft wares, magnificent photos, antiques, bric a brac . . . and more! Crafts and arts are of an extremely high quality, and from local producers.
The day we visited, the local bushfire brigade were collecting donations at the entry gate, but this was the only cost to get in.
There's plenty to interest the whole family - not bad value for a day out.
