Zion
Zion was rugged, beautiful, and downright impressive (until we made it to Bryce and the Grand Canyon).  It is the best run national park I have ever been to, anywhere in the world.  Most of the park no longer has car access.  There are shuttle buses that run every 6 minutes from one stop to the next.  There are trails at every stop, and usually nice vistas.  There were lots of German tourists as well.  I think I have seen more Germans on this trip than in my numerous trips to Germany.
