This attraction is ADA accessible. Although the handicap parking is in the "paid parking" area, handicap parking is free. This attraction gets a full 5 stars from us!
There is a picnic area just before you get to the falls, so it's a lovely spot to have a snack or picnic lunch and hang out for a while.
We didn't get the chance to check out whether or not the lower power houses were ADA accessible.
