This is a great route approaching Mt Whitney and giving access to the Mountaineer's Route
. The trail is usually done in about three days, though more time can be taken to acclimate to the elevation. This trail skirts the crowds of the Mt. Whitney Trail in favor of a more technical, but more rewarding approach.
The trail begins sharing the Mt. Whitney Trail, then cuts off to the north at the North Fork of Lone Pine Creek. This is where the steep terrain begins. The first technical challenge is the Ebersbacher Ledges. I recommend helmets for falling rock, as well as time spent studying a guide book as to where you first climb on to the ledges. Continue on along the trail, and camp at either Upper Boy Scout, or Iceberg Lake. The further you make it the first day the smaller your task on summit day, if you summit, or the more you'll get to enjoy before your way back down.
