Walking backward while talking is useful for leading a tour, demonstrating a moonwalk, or retreating from a room full of ominously staring toddlers. See the reverse saunter put to good use with today's Groupon: for $25, you get an all-day Niagara Falls outing from ISX Tours. This Groupon is valid for the tours on Saturday, August 27; Sunday, August 28; Saturday, September 10; and Sunday, September 11. Tours depart at 10 a.m. from 100 Queens Park outside the Museum subway station.

ISX Tours' passionate guides illuminate Canada's cultural and geographic diversity, blazing charter bus trails to camera-worthy destinations. During the Niagara Falls day trip, guests hop aboard spacious charter buses from Pacific Western Transportation, whose gentle purr harmonizes with sing-a-longs on the all-day expedition. Buses that depart on August 28 or September 11 release passengers outside of one of Ontario's award-winning wineries, where oenophiles can tour the premises and sample wines while scoping out new bottle-homes for miniature ships. Alternatively, buses that depart on August 27 or September 10 lead passengers to the Canada One Factory Outlets mall teeming with 40 brand-name stores. Next, tour groups infiltrate Niagara-on-the-Lake, admiring quaint shops and historic sites. Buses then cruise alongside the Niagara River, stopping at Whirlpool Gorge for passengers to marvel at its circular currents that stem from schools of indecisive fish. While in Niagara Falls, clients can also opt to embark on a Maid of the Mist boat tour or climb to the top of the Skylon Tower. Alternatively, sightseers can spend their day meandering through Niagara Falls before hopping back on the bus and reuniting with Toronto by 8:30 p.m.
