The rock at the area is a hard, red, quartzose sandstone (somewhat reminiscent of the rock at Mt Arapiles) that could almost be confused for granite. The main pinnacle is the size of a large building and about 15m high, and there are a number of smaller boulders located nearby as well. The front side of the pinnacle is fairly low angled and quite shattered, and would be an excellent place to bring beginners. The sides and back of the pinnacle, as well as some of the isolated smaller boulders are steeper and / or less featured and offer a variety of harder problems.
Although the area offers a reasonable selection of bouldering, most of the best looking problems require a rope (due to both the height as well as the bad landings under the shorter problems around the back of the pinnacle).
Descent off the top of the pinnacle isn't immediately obvious, but it's possible to pick an easy line down the front face of the pinnacle if you get stranded. It's probably better for beginners to be lowered off or abseil off after completing a problem since the downclimb is quite exposed. There are no bolts anywhere here, so bring a selection of natural gear (including large cams) if you intend to set topropes.
Local climbing groups meet at the pinnacle every Sunday, making this the best time to visit if you're only briefly in town and don't have a full selection of gear.
