Beachy Head

I'm planning some seascape trips a bit further afield than my local Suffolk coast and Beachy Head is on the list.

Can anyone local (or with knowledge of the area) help me out with good viewpoints and best places to go to get down on to the beach in that area, parking etc.

I'm planning on going in the next couple of weeks probably for sunrise... any local info would be much appreciated.

Thanks
