Keith me and my mate joined last year. There is a big fence at the beginning of the pier and you buy a key for a fiver when you join-me and my mate share my key-but we have only been on a couple of times. It is a canny walk from the top all the way down but if you are disabled you can drive down the hill-think you need some sort of pass as there is a barrier.
the end of the pier is snag city. Half way up fishing onto the sand is the best bet.
Don,t know out about the green wall.
Mick.
