Every time I see a mention of Castellabate I have this urge to go SHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH Don't tell everybody! I really love that area, and in particular San Marco. If I get overly stressed , or just feel a great need to unwind, that is where I like to go (Spring and Autumn only - I would not wish to be there with the crowds in August - I believe it gets extremely busy).
It is a beautiful area with a great beach, good walking, and some superb restaurants.
