8 meters of average rock. Handy if you are a local and desperate.


A small bouldering area in the bush, with sharp, pocketed sandstone providing a few problems and a short traverse.

Access issues

The crag is in bush parkland, close to part of the Two Valleys Track (TVT) in Canterbury council area.


Park at the end of Unwin Street, Undercliffe, or walk from Tempe train station. Take walking track that starts by the water treatment plant. The boulder is on your right after 20 meters.

The secret's in the topping.

About 20m left of the main cliff (looking in) is another small outcrop.

Grab the pointy bit and fly over the top.

FA: Graham Dowden, 26 Apr 2019

Start on the lower level at the crack as for Loop the loop. Move right and then directly up to meet the start of Sharp Angle. Up and top out.

FA: Dan Adijans, 26 May 2019

Start on the lower level at the crack. Move right along the lower level to the far end, before bumping up to the lip and traversing it leftwards to end where you began.

FA: dwebster, Jan 2018

Getting full value out of this wall by zigging and zagging your way up.

Start as for 'Loop the loop' but once you get to the nose on the arete zag back down on the next band of edges up. Follow this to the far right, then move up to the next band of edges and go left (a longer move here) to top out.

Done without using any hand holds twice. The best way to do some endurance training on this wall. Reverse once at top for more value.

Set by Phillip Booth

One mover slapping from low left hand side-pull in the weakness to the big break. Continue up easily to top out.

FA: Phillip Booth, 2020

Starting as for Loop the Loop. Contrived eliminate traversing from left to right keeping hands below (and out of) the big break, utilising the slopes and small holds. Lower break towards the end is in however. Finish matched on far right jugs or continue for easy top out above.
