Hillside 
Http://hillside.camp 
- Men only.  
- Sex in public generally okay.  
- No restaurant  
- Pool 
- Great bonfire pit 
- Has a 'rougher/more hardcore' sex vibe.  
- Site is on a mountainside, so it's, well, hilly.  
I've not been to Hillside for a couple of years, so bear that in mind.  
The Woods is great for day trips- the pool is huge and very active, and proximity to Philly/NJ/NY is a plus. Have only attended on leather weekend at The Woods. Had a great time, but would go with Hillside if I had to choose.  
There's also Oneida, which I believe is primarily women. Also Rainbow Mountain Resort. I don't know if Rainbow has campsites. They do have a hotel (and cabins?)
