Another option (I have not yet done) would be the "Panoramic Loop". Starts at Lake George trail head for Mammoth Crest Hike, and finishes at Trail head for Duck Pass/lake. See following link for more details.

Perhaps longer than you would like, and requires someone pick you up (or add 2 miles to get back to your car).
