Fishing Bridge Campground to Livingston

Best route IMO is Fishing Bridge to Canyon Jct to Norris Jct to Mammoth area, then take the "new-old" road to the north entrance & Gardiner.  Definitely go slow & careful down to Mammoth (lots of switchbacks) and then follow signs at the north end of Mammoth area (past the post office) to Gardiner.  The old road was washed out by a flood a couple years ago and the new one is actually a paving over of the old stagecoach road.  Take that one slow too - not as many switchbacks as the old north entrance road, but still some good stretches of downhill with lots of traffic both directions, and not super wide.   We haven't towed on the new road yet but did drive it in our pickup last summer.  It's been a lifesaver for the folks in Gardiner, Cooke City and Silver Gate!
