The Sears tower in Chicago?

Travel Info
Well I am just interested, is it possible when you come in Chicago to see the Sears tower from inside or to see the top of the building.Thanks. = )

Travel Tips

Ivan, the observation deck on the Sears tower is open 365 days. I, personally, prefer the observation deck at the John Hancock building because, since you're not as high as on the Sears Tower, your view is a little bit better.

Yes, there is a public observatory you can go nearly to the top.
yes and yes
yes
Sure is! I was up top at the observation deck once at sunset, and it was one of the most beautiful things I ever saw. It's a must-see if you are there.
yes it is. Tickets are available from the ground floor to what they call skydeck.
Yes, there is an Observation Deck on the 103rd Floor...can't go to the roof, though, but if you charter a small plane from Palwaukee Airport, you can fly around the city and see the roof.
