To the west of Savage and Carter lakes in the Holy Cross Wilderness Area is Josephine Lake. It's a longer and more strenuous hike than the Savage-Carter loop, but one worth doing once you've done the others.
To reach the trailhead, take the North Fork Road (#501), a left turn from the Frying Pan road, a little ways east of Thomasville. It's the same road you take to reach the Savage Lakes trailhead, but you don't need to go nearly as far. Keep a lookout for the signs indicating the trailhead on your left.
