Goolwa Barrages and Murray Mouth

The barrage walk begins from the car park at the end of Barrage Road in Goolwa South, about four kilometres from the town centre. A lock gate sits mid-span and interpretive displays explain the engineering challenge of managing one of Australia's most stressed river systems. Seals regularly haul out on the barrage structure, and the bird life across the adjacent Coorong wetlands is exceptional.

The Murray Mouth itself, the opening to the Southern Ocean, lies a short walk beyond the barrage and can also be reached on a longer loop trail along Goolwa Beach. A number of tour operators run cruises from Goolwa Wharf that include the barrages and the Murray Mouth in their route, allowing visitors to view the site from the water and observe the shallow sandbar that has periodically closed the mouth entirely during low-flow periods.

The site is free and open daily, with picnic tables, barbecues, and a kayak launch point. No facilities beyond these are present, so visitors should bring water and sun protection for longer walks.
