I've stopped by a few times and it always seems very busy so I never went in.
However I stopped by on new years day and there was hardly anyone here, which made the experience very peaceful.
It's $20+ dollars to get in per car.
There are some beautiful spots on top of hills here.
The waterfall is pretty big and there are some pretty cool viewing angles.
There are random caves you can walk/crawl into.
Streams/rivers have pretty clear water.
It's a very pretty place.
The water was a little low at the time I went, which is no fault of the park itself.
So I imagine with the water up a bit it looks even better. The pictures I have don't really do it justice.
I would come back, but tbh only if I knew it wasn't going to be as busy as it usually seems.
UPDATE:
Went back, was going 18mph when the limit is 10. Should've gone slower but it's very hilly so speed your speed fluctuates without noticing.
Officers stopped and told us to slow down and let us go. Understandable, but he had a bit of an attitude the way he handled it. Could be a bad day, but it was part of the experience.
