The picturesque Polly McQuinns is located on Seven Creeks. It is 4 km south-east of Strathbogie and comprises a reservoir, weir, bridge, and a pleasant area around the water. Once a natural creek and large deep-water pool, the creek has been dammed on the northern side of the road, creating another large waterbody. The dam is a three-sided concrete weir (1920-30s) with a brand new bridge. To reach Polly McQuinns, travel south through the Strathbogie township, go over Smiths Bridge and take the next road to the right, signposted 'Polly McQuinns'.

The water spills over the concrete weir wall, under the road bridge, over large exposed granite boulders and across a natural spillway into the deep-water pool. The two distinctive water features and rocky spillway create an attractive place for picnic and walks. The deep-water pool is fringed with reeds and trees, and there are picturesque rock groupings and cascades.

History: The weir takes its name from Polly McQuinn, an early settler who lived in the area. He was allegedly named Polly because he could not grow a beard. Local lore has it that when he was driving home in his horse and jinker one night he missed the bridge, fell into the water and drowned. There is a rumour that the waterhole is bottomless which is why no trace of him or his horse was ever found.
