Through any travel office you can sign up for a wine cruise along the Mosul river. They start and end at many different towns. In the fall, be sure to take the "Rhien in Flames" tour. Its a wine cruise down the Rhine river while all the towns you pass are lighting off fireworks!
If you're lucky to have "JAFA-Rease" or "rmbtac" on your friends' list then you have a pretty good chance to get into the base itself. Personally, I enjoyed going there for shopping. There are so many little things I got addicted to while living in the US and unfortunately I can't get them in the Netherlands or any other European country. (I will not post here the whole list 'cause I'm sure that many of you will strat laughing out very loud).
But it is also very interesting to see all these huge jets. You'll find about 4 of them there, for the first time in my life I've seen these things and was able to take a picture. Definitely a great experience
