As it is tucked away at the bottom of the gorge it does stay shaded in the morning, but its north facing aspect opens it up to the sun for the rest of the day. Best to climb when its overcast but unsuitable for rainy weather. In winter the warm sun makes being at the crag totally bearable.
The climbing here lends itself to harder moderate climbing with smatterings of trad climbing on the fringes. Routes are mostly overhanging and quite powerful. These routes do not see much traffic so be prepared to do some cleaning and potentially make friends with a wasps nest or two. Pump House will seep after heavy rains for about 3 days.
The base of the crag can be awkward as you must belay standing on a wall against the base of the crag. There are however great flat spots a few metres back to stow gear and watch climbing. Pump House is the first crag you get to in the gorge. It has a shorter walk-in making it convenient for time sensitive sessions.
From the parking follow the dirt road passed some houses on your left, the road turns to a 4x4 track with a garage on your right. Follow this track into the gorge as it turns to a steep concrete road. Walk down the road, passed the water pump-house and down the stairs. Pump House is the looming rock face on your right behind the small building.
