The 6 Best Attractions in Toronto

Toronto's civic heart in front of the curved twin towers of City Hall, home to the illuminated 3D TORONTO sign that everyone photographs. In winter the reflecting pool becomes a skating rink; in summer it hosts markets and festivals. It is a working public plaza, so expect construction hoardings and heavy crowds during events.

Canada's largest zoo, spread over 287 hectares in Scarborough with more than 3,000 animals grouped into geographic regions from the Americas to Africa and the Indo-Malaya pavilion. Plan a full day and a lot of walking, or ride the Zoomobile between areas. It is far from downtown, so budget 45 minutes or more each way by transit or car.

Toronto's 553-metre defining landmark, with a glass floor, LookOut level and the SkyPod higher up. The views are genuinely great on a clear day. It's touristy and pricey (adult from about $43), so go for a clear-weather visit and consider timing it for sunset.

A genuine 1914 Gothic-revival castle on the hill above midtown, complete with towers, secret passages and formal gardens. Worth it if you love grand architecture or have kids; skip if you expect a furnished, story-rich historic home. Adult admission runs about $45 plus tax, timed entry.

A pretty, historic town about 90 minutes from Toronto at the heart of Ontario wine country, with flower-lined Queen Street, patios and 100-plus wineries nearby. A lovely day trip, but you really want a car or a tour, and if you're driving to taste wine, bring a designated driver.

A slick, modern aquarium at the base of the CN Tower, best known for its moving-walkway shark tunnel. Great for families and a solid rainy-day pick, but it's pricey and gets packed. Buy timed tickets online, visit off-peak, and consider the after-5pm discount.
