Loop trail for Beginners

My wife and I want to try a multi day loop trail. We are 26 both in good physical condition, but are not experienced hikers. So I'm only worried about getting lost not the trail being too difficult for us. Any ideas for a loop trail that would be marked halfway decently so that it wouldn't be to difficult to find our way. Peaks aren't really a must, but some good scenery and difficult sections of hiking would be fun. Also if possible I would prefer to hike somewhere that isn't terribly busy. Although I realize that may be somewhat difficult since I would like to have a well marked trail.
Thanks,
Ben
