Within easy reach of the city, if not already in the city proper, are two of the world's record-breaking landmarks: the CN Tower, which is the tallest free-standing structure in the world, offers spectacular views from its observation deck; and the famous Niagara Falls, one of the widest falls in the world and North America's most powerful, which straddles the border between the United States and Canada just 75 miles south of the city.
Sports fans can visit an architectural wonder of their own near Toronto's Financial District. Look up in the Rogers Centre, home of the Bluejays baseball team, and see the world's first retractable roof. Catch a game there and make a pilgrimage to the nearby Hockey Hall of Fame to view famous jerseys and catch a glimpse of the actual Stanley Cup.
Shoppers have their own "world wonder" to explore as well. Toronto's PATH system, the largest underground shopping complex in the world, covers 16 miles of shops, entertainment centers, and many other businesses. Access it easily from hundreds of entrances throughout the city.
As well as boasting modern architectural marvels, Toronto is chock full of historic buildings both charming and stately. The lovely neighborhood of Cabbagetown boasts the largest collection of refurbished Victorian buildings in North America, and Casa Loma, an immense medieval-style castle, overlooks the city and offers tours of its 98 rooms.
Nature lovers who want a short getaway from the stone and steel of the city can just take a short ferry from the Toronto HarbourFront to The Islands, an archipelago of eight islands that contain the city's largest parks system.
Getting out to The Beaches is a fun getaway for families, too. And you'll also find plenty of exciting fun for youngsters and the young at heart in the greater Toronto area, including Wild Water World, Canada's largest water park; the African Lion Safari; the 710-acre Toronto Zoo, and the rollercoasters of Wonderland theme park.
