On top of the balloon flight which is a must when going to Cappadocia, there is quite a lot else to see. There are several torus organized bringing you around the area. Bare in mind that tou can do the balloon flight and one of the tours in the same day (time wise) 

This is for sure one of the most amazing experiences out there. I am sure that there are many others but, this one needs to be high on anyone's list.
