The Lion Head Winter Route itself is very short - I've done it in under an hour.......it's merely a connector between the Huntington Ravine Fire Road and the Lion Head Trail, which is more avalanche-prone in the winter time.
I guess I should've clarified that the trailhead to summit takes 4-6 hours....but the actual Lion Head Winter Route takes less than 2. Sorry 'bout that.
