We camped in tents on 3/2018 and we paid 20 dollars per night per site. The gentleman that used to run the place was amazing. And very easy going. He is not longer there but his wife is nice too. We enjoyed the river and found shark teeth and other fossils. We took a canoe trip and it was fantastic. The park has lots of shade.
The cost depends on what type of camping. Tents in the wilderness area is the least expensive around $12 and RV sites with full hookup was $30 - $33.00 per night.
I dknt recall, but less than 15, i think it was 10.
