It's 21 bucks for 3 people then 7 dollars for every orher person a night dogs are allowed not sure about reserving a spot but you could go mark a spot with a tent, Yes It Is first come first serve
Its first come first serve, you can bring your dog, when i stayed for 2 nights i think it was 28$ or 35$ not sure, but it was fun, there are port a potties all over, no regular bathrooms.
I can't quite remember the prices, but it's very reasonable. In my experience it's always been 1st come 1st served.
