A very popular camping and swimming spot during summer. This site is suitable for swimming following three or more days of no rainfall and if the river is clear. This reserve is located at the northern end of the Cheltenham Hunterville Road just before State Highway 54 crosses the bridge to become the Vinegar Hill Road. Find out more information here. Is it safe for swimming? Water quality at Vinegar Hill is generally safe for swimming, except during and after high levels of rainfall. Rain washes bacteria and sediment off streets, roads, plants and land into water which increases the health-risk and makes it look murky.
