New signage has appeared at the start of the track, it is now private property but the track can be used by walkers. All the climbers bolts have been removed and/or cut so almost pristine arch restored!
Now you have to walk all the way which is only a km or so as vehicles are not allowed, in fact there is a temporary barrier at the start of the track, I assume until a proper gate can be placed.
None of this will affect the Picnic so all is well.
