The falls are just beautiful. We visited on a warm, sunny weekend and there was no room in the parking lot; cars were parked haphazardly along the side of the road. It was sad to see just a beautiful place being trampled by so many cars and people and there was some trash, too. We had a bag with us and picked-up what we could.
Still, it is a place well worth stopping and looking if you are in the area - it takes no time at all.
If you have young children or adventurous teens keep them in hand - many people have died by going off trail and trying to see more. There are fences for protection in the authorized areas. Stick to those areas.
