The tower can be accessed and climbed, but you need to book a ticket that gives you a time that you can walk up, there could be a wait of a couple of hours.
Whilst waiting you can do what all the other tourists do and surround the tower to take cheesy photos of your loved ones pretending to hold the tower up.
Unfortunately the area around these magnificent structures are taken up with cheap touristy markets, with many of the vendors walking around on foot shoving fake branded watches and sunglasses in your face.
