Recomended Beach in West Sussex
Church Norton is a very quiet beach used by nudists. Its a little walk from the car park but ideal for hanging out nude with not too much traffic passing by. We use it from time to time.
Eastney's good as well and official but a bit further West than you may want
Try Climping Beach (near to Littlehampton) not an official beach but many locals go there !
Climping Beach is also known as West Beach. You can get to it from Littlehampton - catch the ferry across the river and go west along the dunes. Or road access is via Climping, the beach is well sign posted and there is a large car park and refreshment hut.
You can go nude in the dunes but it's not really accepted to walk down to the sea or along the beach naked.
There is a warden, I have been informed,that patrols the beach sometimes and nudity is tolerated although not official.
