Perth Rock (2013) lists 36 boulder problems across the different areas, from V0 to V4, although a lot of the fun comes from making up your own challenges.
A stretch of weathered limestone cliffs beside the Swan River, arguably Perth's best outdoor training site. Most opportunities for climbing involve traversing the several hundred metre-long cliff. However, there are a number of 8-10m faces above deeper water, providing an opportunity for soloing in relative safety.
Park at the Point Walter carpark and follow the paths around to the cliff (~500m). Alternatively, park on Honour Drive near the golf course tee and follow the fenced tracks down.
