I hadn’t spent much time exploring Leura before, and so was surprised to discover Sublime Point when we were visiting friends nearby. It has a better view in my opinion than Wenty Falls or even Echo Point, since you can see both valleys.
View to Katoomba.
View to the Kings Tableland.

And because access is via some very quiet suburban streets, there are no walks from it, and parking is limited, it seems to be one of the more secluded lookouts in the Mountains. Bonus!
