Yep
I tend to go up there quite a bit as for an hour and a half journey it certainly packs more excitement than round here IMO. Purple Mountain Cafe is good too.
I tend to do a slightly shortened version of the red route - starting at visitor centre following up to Dixons Hollow but then cutting across to miss out the top loop (Adderstone and some of Jerry Noddle)which gives me a good steady 3hrs with sandwitch stop at Dixons Hollow - which is plenty enough for me - but will obviously go with what ever.
