A fairly grubby crag upstream (and therefore in no danger from) the sewer works on Stockdill Drive near Macgregor. Access is difficult to describe and very much cross country - essentially park right near the plant and walk to google maps coord -35.258971,148.981025
Septic Sector & Cave Routes have straightforward access following the directions below, but sewer wall has many routes starting with a hairy traverse over the water on untrustworthy bolts. Ideally you would abseil in to get to the cliff, but there are a few issues with this - firstly there are no trustworthy trees up top, nor anywhere to place gear for an abseil, and secondly between half to the entire cliff has water at the bottom depending on recent rain!
As you approach there is a very steep ramp to the left that can be used to access the cliff. Be careful.
As of last view (early 2010) the bolts on Sewer Wall were rusting and may not be trustworthy. This is not a well-attended crag - climb here at your own risk, it's an adventure even finding it. Septic Sector & Cave Routes were bolted 2014
Located about 10 minutes drive from Belconnen and a 20min walk, climbs vary in height from 8-55m, although the original (and longer, harder) climbs have not yet been rebolted and are probably NOT SAFE.
The original wall is in shade most of the day but through Summer Septic Sector & the Cave Routes are in full sun in the afternoon. The water is a great way to cool off; it's upstream from the water treatment plant so you're safe & it's usually a nice temperature throughout the warmer months.
It gets dark very quickly once the sun touches the Brindabellas in the West, and the start of the track back can be difficult to find, so pack a torch, as well as a camera not just for the climbs but for awesome scenery and an abundance of turtles, lizards &, yes, piranha carp.
Get yourself to Stockdill Dr, Holt, & follow it a way until you can glimpse the water treatment plant in the gaps between trees.
Drive past Shepherd's Lookout to a locked gate on your left & a plastic bollard with various pictograms saying what you can't do. Go over this gate as it is in Nature Reserve, whilst the paddock on the left is Private Property.
Follow the fenceline (keeping it on your left) and some feint wheeltracks below the dam and keep following it until you reach another gate in the corner. Turn left and keep hugging the fenceline an following feint vehicle tracks crossing the first gully & then passing just to the right of 2 large trees on top of the following crest. Continue straight as the track crosses another gully, and keep hugging the fenceline until it takes a left hand dog leg. At this point you want to walk directly SSW towards the river. you should be able to follow some animal tracks to a very large gum on the edge of the cliff. This is the top of Cave Routes.
Follow the trail downhill & left (upstream), staying close to the cliff until, just after stepping over a fallen tree, there's a clearing to your right & a lone tree near the edge of a 15m cliff. About 4m past the tree is the top of Hung Like A Sewer Rat, & you can scramble around Septic Sector from here.
Follow the river downstream to the obvious big wall for Sewer Wall.
