North Lake over Lamarck Col to Evolution, then north on JMT over Muir Pass to Leconte, then exit over Dusy/Bishop Pass to South Lake. Do this as a 2 nighter as you seem to be fast, 3 nights if you want to fish.
did you know the NPS is actively netting trout to exterminate them from high lakes in SEKI? Trout were introduced, therefore are alien species to the area. Harvey
