Start time could be flexible. Hiked this a few weeks ago, and it was even better than I remembered. Kinda gnarly, 5.2 mi. RT, w/some great rock scrambling, summit exploring, and holy-crap views.
Last I drove in, North Fayston Rd was totally blocked off halfway down for major construction/repair. Recommend Center Fayston Rd approach, unless you have time to test the alternative.
