Victoria Harbour Ferries offer one hour narrated tours of both the Lower Harbour and the Upper Harbour, or Gorge.    The Lower Harbour tour is ideal for younger children, as it features sea planes taking off and landing, harbour seals, floating villages, and a chance to roam the docks at Fisherman's Wharf and enjoy Barb's Fish and Chips or an ice cream cone. The Gorge tour, on the other hand, is perfect for history buffs and anyone who wants to learn more about this city's long and interesting colonial past, as well as see some parts of the city that are only visible from a ferry.  (The Gorge is a winding, scenic tidal inlet that runs from the front of the Empress Hotel all the way up to the reversing waterfall at Tillicum Road, where early Victorians used to frolic and picnic in the warm and welcoming waters.)  One of the highlights of the Inner Harbour during the summer is the Harbour Ferry Ballet, 10:45 a.m. every Sunday, when a small flotilla of these cute, highly maneuverable ferries puts on a display of pinwheels, figure eights and in-line dashes that delight the thousands of spectators lining the Lower Causeway in front of the Empress Hotel and the Parliaments Buildings.
