Question about rock climbing/rappelling

I have yet to visit HH and know that there are roughly 90 some acers in the park set aside for rock climbing activities but was looking to bring my own equipment as I have everything I need (no petons as I saw on your site a year or two ago stating they are not allowed due to the soft sandstone in the park) to climb/rappel and I know how to use my equipment and how to tie off to trees in places that petons cant be used, all this in mind would I be allowed to do so at HH all knowing if so I would be doing so at my own risk?
