Six days total as follows camping at Soldier Lake over New Army Pass, Guitar Lake, summit Mt Whitney and camp at Crabtree Meadow, Soldier Lake, half day hike to Sky Blue Lake and camp at High Lake then back to trailhead. Total of about 65 - 70 miles via the Pacific Crest & John Muir trails (no cross country). Hiking to Sky Blue Lake is not difficult as I follow Rock Creek to the base of the wall where the creek ends and then over the wall to Sky Blue Lake. There are other ways to go where there is not as much elevation gain/loss via the north end of Soldier Lake. Hope that helps. If you have added questions by all means don't hesitate to ask.
