Take a ride along the oldest public railway line in Australia between the towns of Victor Harbor, Port Elliot, and Goolwa aboard the historic, iconic Cockle Train. Built in 1887 to ferry goods from the last navigable port on the Murray River (Goolwa) to the seaports of Port Elliot and Victor Harbor, the 30-minute steam-train trip quickly became a popular trip for tourists as well, earning its rather quaint name from the large cockles that the sandy surf beaches of Goolwa are famous for. The train only runs on Wednesdays and Sundays (daily during school holidays), so a good alternative if you've got bicycles with you is the 30km (19-mile) Encounter Bikeway, a dedicated bike path between the Bluff and Signal Point at Goolwa Wharf. The sealed path is suitable for escorted toddlers on tricycles through to those wanting a gentle, seaside cycle. (You can also walk a section of it.) Between June and October, you may be able to spot southern right whales as you ride.
