5 Day Blue Mountains Walk

Hi. I'd like to do a five day walk in the Blue Mountains in spring. Ideally the walk would be contiguous without the need to transit between two walks. The group I’m walking with is experienced, and would be happy for a “medium” grade with some hard sections if required. Looks like there are some great 2 – 3 day options. Wondering if someone can suggest a five day walk! Thanks, Dean
