In reply to ncianca: You can still climb there as the following story clearly illustrates. Be warned.
Several years ago a lady in the cafe saw me and my mate climbing there and thought that we had been trapped by the tide so called the rescue services out. As we walked back along the top all we could see were blue and orange lights flashing as numerous coast guard, police and ambulance vehicles waited for us as two helicopters circled above. We even made the evening news that night. I think they were all more embarrassed than we were.
I can't recollect but this suggests that there is a way out.
