Correct location
I stayed here for one night. It is $5 per night. I had decent Verizon signal. There were at least eight camping areas. While I stayed here about half were full. The camping limit for this area is 14 days. There is a camping host that lives here so you cannot overnight park for free. There is river access. The only plot that I found that I could use my hammock at was plot 8. Just because of the lack of strong trees.
