There is only a charge to camp in Ricardo Campground. Besides thst you can explore the park for free.
National parks are not always free and with the conflicting answers I would either call to be sure about any costs or, just be prepared Boy Scout.
It's a national park. Its free. You just drive up to the rock and admire.
Day use is $6 per day per car. 1 year state park pass is $195.
The park is free, overnight stay has a base price per vehicle on the campground.
