These climbs are usually accessed by abseiling down from the top to a ledge 6m above the ground (a continuation of the ledge running from Sector A). It is possible to abseil all the way to the ground and find the routes, but this means lots of bushwhacking to find the way. Many of these routes originally started from the ground, moving up to the ledge and then to the top.
There is also a set of abseil chains above Quality Street, which by a 45m drop, gives access to Quality Street, Son of a Gun and Wall Street, Tumbleweed and A Twist of Sand
