200m. From the top of the gully follow bolts (grade 3 climbing) out right, then back left up slabby rock to the start of the cables. These lead up and left, round the crux bulge, and along into the huge cave. Finish across the slabs and scamble up the gully.
Decent: walk to the hill top (5 mins) the walk straight down the slope to pick up the old pack-horse trail that leads down the gorge and out past Symplegades.
