The Niagara Grand Tour is the most popular Niagara Falls tour flown by National Helicopters. It is a twenty minute flight that departs the Niagara District Airport and flies over Niagara's world renowned wine producing region on the way toward Brock's Monument in Queenston. Once over Brock's Monument, the aircraft turns southbound along the Niagara River, flying past the Sir Adam Beck Hydroelectric Generating Station, the Whirlpool Rapids, the Spanish Aero Car and the Maid of the Mist below. The tour culminates with an unforgettable view of the American Falls, Bridal Veil and Canadian Horseshoe Falls from high above. The helicopter will make a second pass over the falls so that passengers on the other side of the aircraft get the same view. The helicopter then retraces its route back to the Niagara District Airport.
