I had not enough time to stay in Calgary,so my first thing on my list was to see Calgary Tower.
The ticket is $18,a kind of pricey, but worth it.You can get an audio guide which was very helpful.Many people but not overcrowded.As you walk onto the glass floor it's scary.It takes your breath away for the first minute.Like you fall down but it's cool.Spectacular views!
And audio tour is a plus.You can find a place of interest on the monitor and click on it and listen to the history.So great views of the city and self guiding tour- two in one.
Top place to see!
