I think that there is a $2 parking fee. It is left at an honor box. Could be wrong on the amount but less than $5, because I had to dig for change in my glove box.
Per sign (12/2/21), $4 per vehicle with 8 people max or $2 person.
pay $2 to park and place in box provided.
No costs at the entrance I went. Just a nature trail.
