Attempted to hike from Boone Fork Trailhead (mile 299.9 on the Blue Ridge Parkway) to Callaway Peak at Grandfather Mountain in western North Carolina. Had to turn back about about 2 miles in because foot-deep snow was obscuring the trails. Went up Daniel Boone Boy Scout Trail, which becomes snow-covered past the Flat Rock trail junction. There's a bit less snow on the Cragway Trail, which also has much better views. I'm guessing the snow will be gone by the end of April 2010, perhaps sooner. Trip write-up at Two-Heel Drive
Trail is steep and craggy -- trekking poles come in very handy. If you go up before the snow melts, be careful about following tracks of previous hikers -- they might not have known where they were going.
