The crag is now open after being closed for five years.
Though described in Tim Wethey's Canterbury Rock as "unprepossessing", you may actually find the crag quite prepossessing.
There are some impressive routes over 30 metres high, including long jam cracks, steep bolted arêtes, and routes where you have little idea what's ahead when you leave the ground.
The median grade is 19, and the harder routes tend to be cleaner and better. Extensive cleaning during the early 2010s has improved many of the routes that were formerly very dirty, but a five-year closure has enabled some routes to become dirty again.
The crag is essentially one long cliff line, but to make it easier to orient it has been divided into a serious of "walls", generally separated by more vegetated sections.
In a new innovation the NZAC has funded small aluminium signs to indicate some of the more significant routes, as an aid to orientation. Generally there is one route identified in this way on each wall. In addition a few routes are noted below as being relatively easy to identify.
Hubris; A brown corner system, with a roof to the right of the climb.
Hello Possums: Starts with the short jagged crack
Monarch: The prominent right-facing corner with a huge roof on the right.
The Ghost of Tom Joad: Look for the middle line of new bolts; undercut start.
Big Mama: The black streak to the right of the fence, with three bolts.
Featureless Fault: The brown streaked shallow corner, with the tower above; includes 2 bolts low down.
The cliff is very pleasant on a hot mid-summer nor-west day since it's shady and vegetated. In winter it tends to remain wet.
Another Lindsay Main find, with the first route on the cliff being Eclipse (16) in January 1975. In 1977 he climbed *Monarch (18) with Henry Mares, who put up The Pretender (17). A break-through was made in October 1979, with the ascent of *Brain Damage (20), after which John McCallum and Joe Arts started to take an interest, with many good routes developed in the 1980s and 90s. Later Alan Hill, Richard Kimberley, and Pete Gresham added a new crop of routes prior to the crag being closed for a decade in 2004.
After the crag reopened another major development phase started in 2013, with many routes added and older routes cleaned.
The rock is sometimes shattered, especially near the base of the cliff. Descents are by abseil, generally from double ring anchors, though there are some obscure routes that rely on a tree. Some abseils require two ropes.
