We went there first of October. $30 to get inside the park but if you have a America beautiful pass for $80 it’s good for a year. In the RV area with electric hook ups is more like a parking lot Loop b is pretty much tents only. Loop a there are a few decent size sites 14-19 but you better have reservations. It’s $25 a night for the campground. The hike to the falls is nice and not too bad or long.
