Yes they are within an hours drive. I used to take friends (Japanese, English...) and my students to see them. There is also a hiking trail along the falls itself and crosses the upper falls to go to an interior trail system.
The A.Y. Jackson lookout has numerous viewing points for those that the hike would be too much.
There is a covered section where you (we did it often) have a meal and there was maybe still exist a small museum.
