The access to White Water Wall is now kinda fucked unless you have a 4wd
Most people will find themselves walking in.
Its around 30 minutes to the White Water Wall campsite
But if you are climbing around the Tetragrammaton a new track has started to be developed which takes half that time.
The track has been cairned (could do with a few more) and starts 1/4 way down the 4wd drive track and ends at the top of Tetragrammaton buttress.
I've added the GPS coordinates for the new track here Coastal Crags
