From the upper trailhead, walk up the old roadbed for 2.5 miles to the old terminus for the road where it crossed the main creek. Last time we were on this road in 2009, we could still drive it and sections of it were unrelentingly rocky. Still, you should be able to cover this access in about an hour. Where there use to be parking at the upper terminus, look for the "shortcut" trail that heads more directly west to the lower and upper South Colony Lakes. This trail is the main access for Humboldt or Kit Carson if heading in that direction.
There is plenty of camping available in the vicinity of where the road used to end at 11,000 ft. and all along the trail "shortcut" trail to the lakes and at the lakes.
