The only other outcrop of the dyke that creates the Jane Fonda Workout Wall. At least one route was put up with terrier bolts so development may date back to the 80's. There are around 15 sport routes, almost all grades 18–21, of about 20m height with more holds and (even better) more bolts than JFWW. Each route is at least as good as the best of (say) Transmitter crag, so an excellent crag for a warm day. It is only 100m west of JFWW but it is probably faster to approach from above via the Crater Rim walkway and abseil. Earthquake damage and hazard is relatively low and the rock is mostly good but helmets are worth it as development and traffic have not cleaned off all loose holds.
Apparently one or two trad routes have been done that may be of interest to pushy young alpiners but probably not rock climbers.
The crag is on the Lyttelton Harbour side of the hills, above Livingstone Bay. Drive to Evans Pass on the Summit Road, then 3km further towards Godley Head. At the saddle directly above Taylor's Mistake, park in the lay-by on the right. You could follow either the upper or lower approach to Jane Fonda.
Pick up the track to the base of Jane Fonda. At the Left end of Jane Fonda the track extends Westwards past the base of a rocky pinnacle, then slightly upwards to the base of the Wobbly Wall.
Alternatively. Continue up the walkway Westbound for about 8 minutes. Just past a point above JF, pick up a climbers trail angling down to the right towards an obvious rocky notch. The notch is the east edge of the crag. When the trail peters out descend the broad spur for a minute ending in a distinct grassy ledge with a couple of old warratahs. There is a galvanised double bolt abseil anchor on the uphill side of the ledge, from here it is 30m to the base of the crag.
It is best if a rope is left in place for top-rope egress, as the central route anchors are about 5m below the grassy ledge. Otherwise you could egress via routes on climbers right or by descending and sidling to the base of Jane Fonda.
