I've been more than a few nude beaches over the years, and I live in a country that used to have nude bathing sections in a lot of public pools. Let me add one point (basically for guys): Don't go if you are expecting to pick up chicks. You'll be disappointed.

Hanging out at nude beach is a great experience. Go for yourself to feel free and natural. That is the attitude of most everyone I've ever met there (and the one exception kind of proves the rule, but that is a different story). People aren't there to "see and be seen" as is often the case at a regular beach.
