I was here 2 years ago, had no idea there were camping sites. I only saw hiking trails. Where are the camps, how much are they? What's included?

Check the website. There is different pricing for camping and the beach access. The price is also different for in state and out of state residents.

So going to the beach is separate from camp sites? 17 for beach and 27 to camp, 34$ for an out-of stater to stay and swim?
