Having walked the top of the falls the day before, I can say that the view from the cruise is so much more spectacular.
The boat takes in the sights of the river with an interesting and non-intrusive commentary provided by the driver. Once at the falls the boat stays as long as necessary for people to get photos of themselves in front of the amazing blue and white bubbling water.
Free tea and coffee on board, plenty of seating inside and out. If you can manage the walk down a ramp onto the boat this would be suitable for people with limited mobility as they can stay seated for the whole cruise if they wished.
Highly recommended. $37 for 1 and a half hours was well worth it.
Note that the morning cruise (10.30am) normally has less people on it, and therefore more opportunity to take photos without a crowd.
