Port Adelaide is a very historic area, and was the hub for all shipping activity from the earliest days of the Colony of South Australia. These days there is very little maritime activity, but some of the history remains and it is well worth visiting by boat. Access to the inner port means passing through the twin opening bridges (rail and road) of the Port River Expressway. The hours for opening are very restricted, and instructions for how this can be arranged are on this website.
Some marina berths on the southern side of the basin just before the second opening bridge are owned by Renewal SA (a Government Department), and available for visitor use free of charge for up to three days. No services are available on the marina but nearby public toilets can be used. The access gate is locked every night.
