I've been to the observation deck of several of the tallest towers in the world, so I wasn't going to miss the opportunity to visit the top of the CN Tower on a bright sunny day. It was disappointing that the outdoor walkway was closed due to "weather". As far as I could tell, it was not due to wind, just cold. Of course it's going to be cold out - it's Toronto in February. Come on! One of the two elevators was out of commission while I was there, which made the lines longer than they needed to be. The view was spectacular, although the sun glare off the lake made it hard to see New York.
The admission price is much too expensive. Sky Tower in Auckland, N Seoul Tower, Tower of the Americas - none of them charge even half what the CN Tower charges.
