The siblings go to great heights! Gabby and Maddox visit the historic Niagara Falls and make new friends traveling from Canada. They learn about the rich history of the area and the people who have tried to conquer the powerful falls. Seeking adventure themselves, the kids brave the Cave of Winds and explore the Hurricane Deck at the base of the American Falls. They take a ride on the Maid of the Mist boat tour all the way to the bottom of the Horseshoe Falls. Of course, a trip to Niagara wouldn't be complete without an exciting helicopter ride!
