Having recently turned 30, the funky CN Tower remains every bit as cool and iconic as it was when it opened in 1976. Its primary function is as a radio and TV communications tower, but riding the great glass elevators up the highest freestanding structure (1,800 feet/550 meters) in the world is one of those things in life you just have to do.
On a clear day, the views from the Observation Deck are absolutely astounding; if it's hazy, you won't be able to see a thing. For extra thrills, tread lightly over the knee-trembling Glass Floor deck, or continue climbing an extra 330 ft (100 m) to the uppermost SkyPod viewing area, the highest public observation gallery in the world.
Alternatively, if you're feeling chipper, you might want to enter the annual CN Tower Stair Climb - a heart-thumping dash to the top of the tower's 1,776 steps that happens every October.
The CN Tower is a popular tourist attraction, especially in summer, queues for the elevator can be up to two hours long - going up and coming back down. An IMAX theater and interactive displays add to the experience.
The CN Tower is just north of the Harbourfront Park, in downtown Toronto, and you can easily get here by subway, bus, and streetcar. Nearby attractions include the lakefront, Rogers Centre, Toronto Music Garden, and the Design Exchange.
