Obviously the main attreaction is Maid of the Mist but every part of the tour was amazing in its own way and I suggest you not to skip anything! (specially cave of the winds)
Our tour guide was Nick, who is extremely knowledgeable and very cool, if you are thinking about booking this tour I would STRONGLY recommend you ask for Nick. If he has his little helper with him then you are a lucky person.
