Six day, five night backpack trip into Lone Lakes. 6,210 feet of elevation gain & loss. Good water everywhere except the last day descent out of Seven Lakes. There are springs & seasonal creeks along the way of the last leg out. Optionally could add an extra night stop at Stanley Hot Springs on the way out (likely shared with other campers). 3,153 feet descent and 5 mile hike to Stanley Hot Springs, then 3,624 feet descent and another 4.6 miles to the trailhead.
