If you are interested there is a new smart phone app climbing guide recently released for Dreamtime Wall in the Serra range, Grampians (about 25km south of halls gap over the hill behind Mt Frederick & Mt Lang).
Search the app store for ICrag (same guys who did the Arapiles and around Melbourne Iphone app) - they currently have three iphone apps for sale.
This is just one cliff, but it has a decent number of sport and trad climbs starting at grade 6, with lots in the mid teens as well as some harder stuff for those strong men and women among us. Please do take a helmet and plb as there is still some loose rock and no mobile coverage with any carrier.
The walk in track is well established and the climbing is more thin and technical than steep and thuggy.
Closest official campsite is Jimmy's creek.
Please note the Henham track is currently closed (hopefully not for too much longer) so it's a long walk in on the un-named track 10km along the Serra Road from where you leave the bitumen. If the gate is open you save yourself about 30-45mins of walking. There is also some lovely bush camping along there.
Enjoy - care of ICrag and Rockmaster Publications! (Ps any feedback or suggested changes to josef.goding@gmail.com please).
