The town's commercial centre extends along one side of King George Street and spills into adjoining Market Street and Cullen Street. The other side of King George Street fronts Garden Park - an attractive strip of parkland and trees which extends down to the shores of the wide waterway of Gunbower Creek. In the middle of the creek is the Millennium Fountain, Cohuna's tribute to welcoming in the year 2000.
Cohuna's main natural attraction is Gunbower Island, accessed via Cohuna Island Road. Formed by the Gunbower Creek branching off the Murray River then rejoining it further downstream, Gunbower Island is claimed to be Australia's largest inland island. It has a water frontage of 130 kilometres and is mostly covered by native forests and wetlands, making it an ideal spot for camping, picnics, fishing, boating and bushwalking.
