Iron Mountain Road (16A) is a must do. You will encounter tunnels, pigtail bridges, superb lookouts and 314 curves. It is a scenic delight! The most magical moment of the drive is the view through the Scovel Tunnel where 4 presidential faces greet you at the other end, like a postcard. That leads you to Custer State Park loop and gets you close up bison encounters. Enjoy Re: 40 foot 5th wheel in Yellowston NP Fishing Bridge is the only location that could accommodate our 40 ft Class A. 50 Amp full hookups. Reserve early to get a spot. You will need a minimum of 4 days to see everything, more if the flooded out northern road is open. Call them with sizes of rig and tow vehicle and they will tell you what site is best. Yellowstone has a north and south loop forming a figure eight, FB is near the center.
