I had a great six day trip through the Granite Chief Wilderness, plus some additional country to the north. I went in at Alpine Meadows Trailhead, and out at Squaw Valley Trailhead, with at least 67 miles in between.
Since some people read this blog for trail conditions: Five Lakes Creek cannot be crossed anywhere downstream of the PCT trail crossing, except on logs. The Middle Fork of the American River cannot be crossed at the Picayune Valley trail crossing, but can on a log downstream. The Five Lakes Creek Trail is mostly clear of snow. Upper Grayhorse Trail, upper Picayune Valley Trail, and upper Granite Chief Trail are largely under snow, but the trails can be followed with attention.
