If you are looking for a bit more miles, check out the Thunder Point Loop. Starts on Big Sag, drop into Ottertrack, then into Knife Lake. Swing home via Eddy, Ogish, Alpine, and Sea Gull Lake. There is a "back entrance" (so to speak) to the campground if you end up parking at End of the Trail.
Plenty of places to divert. As YaMarVA mentioned, Cherry, Hanson, Ester, et al.
Here is a link to the loop.
