Alpine Loop for sure. That is super good ride. Though if you are a real green noob, you might avoid Cork Screw Pass. Here is a link to a ride report from my trip a year ago. The first day was a section of the Alpine Loop . Some decent pictures so you can see what it is like.

If interested, this was a 2600 mile ride. A big loop starting in Colorado and going up in to Montana and back.
