Cairns has many very well equipped and challenging skate parks. Some are suited for the older kids and teens, while some cater for all ages and abilities, including quite young kids.
The local council have been busy in recent years making and maintaining a number of bitumen BMX pump tracks. “A pump track is a circuit of rollers, banked turns and features designed to be ridden completely by riders “pumping”—generating momentum by up and down body movements, instead of pedalling or pushing”. Thank you Wikepedia for the definition.
There are many mountain bike clubs in Cairns – and some great facilities to test your skills
