Sunset Strip is indeed an underrated area at the Cathedrals; the vibrant orange colour of the sandstone is quite impressive. I recently did Devil's Pastry Cook and while it felt like an easy tick for grade 18, i'm keen to return. The Cathedrals has an abundance of quality climbing, but as dalai said most of the crags require some full on hiking to get to them.
One place i've never been to though is Cathedral Gorge. Might be planning an exploratory trip in the next few weeks if anyone's interested ?
