Explore the swampier side of Cairns on this revelatory wander into the wetlands. Eerie snap-crackle-slop noises provide a fitting soundtrack to the spooky surrounds, which are signposted with informative guides to the weird life forms scurrying in the mud below you. Slather yourself in mosquito repellent. The boardwalk (and its car park) is just before Cairns Airport.
