A nice side trip if spending some time in Killarney...I wouldn't recommend stopping JUST to see the waterfall and continuing on your way, as it is not really all that impressive. Having said that, we recently got the opportunity to do some of the walks surrounding the waterfall which are pretty nice. All in all, a nice place to spend the afternoon, but hard to do as a 10 minute stop. I should note that there is no charge to park at or enter the park area.
