Radelaide Tours runs small-group tours around Adelaide with a focus on the parts of the city locals actually use. The Port Adelaide tour is the pick of them and runs two and a half hours. It opens with an hour on foot through Port Adelaide, covering the port's history, its characters and the street art that has gone up across the precinct. You then board for a ninety-minute cruise on the Port River, taking in the dolphin sanctuary and the ships graveyard. Tours can be cancelled up to twenty-four hours ahead for a full refund or a reschedule. Inside twenty-four hours there is no refund, and weather cancellations by the operator are refunded in full.
