Open Question: Looking for secluded camping in Washington?

We want a place that's kinda private, like with the campsites nicely spaced out, preferably near the beach or a lake. Trails would be cool too. Activities! and yeah. So, privacy is definitely the most important thing though, I do not want to have to interact with anybody should I want to be alone, if I can see my neighbors, that isn't even camping, I mean come on guys. And it'd be cool if we didn't have to take this huge hike to get there, seeing as how we've only got a few people and a bunch of food and stuff.
