While it's probably best noted as a good escape route from the bottom of the cliff, it's actually not a bad little number in its own right. Some of the climbing might feel a few grades harder than grade 11, but by and large it's possible to find a line that conforms to the grade.
A standard rack of wires and cams (to #3 camalot size) is sufficient, although a #5 camalot is also recommended. Helmets are an absolute must and 60m double ropes are highly recommended as well. Definitely not for the inexperienced.
20m (4) Up the easy ledges then halfway up the right tending gully. Belay off a small tree.
35m (11) Move left along the obvious traverse line then up as you will to the large, steeply sloping ledge. The initial moves up are harder than they look and it's much easier to traverse back onto the wall from further left.
80m (4) Walk up the ledge, trending left initially, then solo up a short 8m wall (might be an idea to belay up this). At the top of this move up and slightly right to the small stand of saplings below the obvious squeeze chimney corner crack (#5 camalot for this belay).
45m (11) Grunt up the squeeze chimney for a move or two then fondly bid it farewell and venture out onto the right wall. Engaging climbing (suss dinnerplates) to the top of a lovely little exposed pinnacle perched in the middle of outer space. Step back to the main wall and up to a spectacular belay ledge.
55m (11) Move right and up the obvious chimney (which is often wet at the back). At the top, head left and up a steep dirty gully for about 15m, passing the two dodgy looking banksia trees. Belay off a small gum further up, with the trusty #5 camalot in a block just to the left.
To get off, walk directly away from the cliff for about 250m and you'll hit the Fortress Ridge walking track. Turn right and follow the track back to the Mt Hay Road, taking the left fork at each junction. It's about 45 minutes of flat walking back to the road.
