Lower Savage Lake, Holy Cross Wilderness Area
Savage Lakes are in the Holy Cross Wilderness area. The trailhead is east of Ruedi Reservoir, in the Fryingpan Valley.
If you go, consider the Savage-Carter loop. Though not "an inventoried trail," there is a way down from Carter Lake, so you don't need to backtrack.
The trailhead to Savage Lakes is near the end of a dirt road that branches off to your left as you head up the Fryingpan River valley east of Thomasville.
