Last year a few people commented on one of my photos in the Training Forum from a sport climbing day. In the background was the impressive tiered face of Mt Banks, possibly the tallest cliff in Australia's Blue Mountains, depending on how you count. It's about 500m high.
We traversed it across the middle from right to left, using the second vegetated ledge.
Mt Banks was kind of the "First Great Problem" for Blue Mountains climbers in the 1950s, with the legendary Original Route requiring a few seasons of siege tactics and bivvies.
After that era it has been extremely rarely revisited by climbers. The muddy, black, chossy, and badly protected jungle mountaineering was abandoned for the sun-kissed orange jugs and clean splitter cracks found elsewhere. There are some modern routes tackling cleaner unbroken sections, but the tallest Central Gully section has been mostly abandoned, too steep for walkers and too vegetated and chossy for climbers.
In 2015 a party from the Springwood Bushwalking club discovered a hidden ledge, that allows you to link an unlikely 3rd-class traverse horizontally across the whole face. This was nicknamed the "Traverse of the Gods".
We got together a party of 5 of fairly experienced Blue Mountains hikers and climbers. I was actually worried we had too much climbing ability, as we might go try forcing passage into more difficult free solo terrain instead of backing off and finding the proper hiker-friendly passage. (Spoiler alert - this happened)
To start off there's an easy 1 hour walk on a dirt road around the back. Then you do a short scramble down to the main ledge system and we were off.
