Or you could just dayhike them. Bago is straightforward via Kearsarge Pass. For Gardiner, hike over Kearsarge Pass and turn north on the JMT shortly before Charlotte Lake. When the JMT turns right at about 11,100 feet, head NW across an obvious bowl. Climb out of the bowl and continue NW to "Charlotte Col" at the south end of Sixty Lakes Basin. Drop down about 300 feet into the basin using the chute just west of the low point. There is much loose rock on this descent. Traverse directly to Sixty Lakes Col without losing or gaining elevation. This traverse has surprisingly decent rock. Climb down into Gardiner Basin and head for Mt. Gardiner. This approach saves considerable mileage and elevation gain over following the JMT all the way to Rae Lakes before reaching Sixty Lakes Basin. The cross-country travel is strenuous, so not everyone will prefer this route to the trail.
