On a recent visit to Pine Valley we shared the ferry ride to Narcissus with a group of Europeans heading up the range for a relaxing bit of highlining ( tightrope walking by another name ).
Apparently these guys had already been down to the Tasman Peninsula and were off to Frenchmans Cap after Pine Valley to test their luck there.
I haven't seen any footage of the Peninsula or Frenchmans Cap but some a video of their escapades highlining Geryon's gun sight has been posted on Vimeo.
I hope this link works;

If this doesn't get you there search for, "The Book of Laughter and Forgetting" on Vimeo.
It's not a Du Cane Traverse route I would recommend and definitely goes off track a bit !!
