Wrens Flat is a free, dog-friendly bush campground situated on the South Branch of the Jamieson River in Victoria's High Country, within the Jamieson State Forest.

Access requires a four-wheel drive, and travellers should exercise extra caution on the approach road, which sustained damage from an earthquake. There are no facilities on site, and visitors must pack out all rubbish.

The campground is reachable via Mt Sunday Road and sits within a broader network of riverside camps and 4WD tracks in the Jamieson region. Swimming is possible at the site.

Like other camps along the Jamieson River, the area is subject to seasonal road closures during the snow season, so checking current access conditions before visiting is advisable.
