The bouldering is pretty much all on the western side of balls head on a 4m high wall. There are some toprope anchors and a good long traverse. There is also a huge detached block down near the water on the southern side of the headland. The block is covered in bolts, with about 5 climbs with many variants.
NOTE: Balls Head has been closed to climbing by the local council, because of severe erosion in the area (source: Rock No 26, Autumn 1996). Keep an eye out for more information as to when / if it will be reopened.
The guide for the area is the newly published Sun, Surf and Sandstone online guide book. This crag is described here.
