Mount Lemmon and hiking trails

Tomorrow I am going down to Mount Lemmon to see the fall colors as they are supposed to be at their peak right now. While there I would like to do some hiking. Can someone recommend some hiking trails that are about 4-6 miles long and in the easy-moderate range? Thanks everyone.

I haven't hiked there yet, but found these websites: http://arizona.sierraclub.org/trail_guide/HIKE1.HTM http://www.virtualtucsonmagazine.com/main/mountains/palisade_trail.html
