West Yellowstone south to I80

I would take 26/287 to Dubois and then hit I-80 at Rawlins. There is a nice campground in Dubois called the Long Horn Ranch and RV Park. A few more campgrounds you might like: At Lincoln, jump off I-80 to Nebraska Rt 2. At Nebraska City, stay on Rt 2 into Iowa for about 10 miles and you'll hit Waubonsie State Park. $16 a night for electric.Then go back and get on I-29 south to Rt -36 across Missouri. This is a nice 4 lane highway with a 65mph speed limit. We stayed at Pershing State Park which is right off Rt 36. $19 a night with electric.

Thank you all for your responses! We would love to stay over in the places you all mentioned but at that point we will be pushing 3 weeks and need to be getting home! Our concern was mostly the roads and if there were any concerns we should avoid with our motor home and trying to see the best scenery while trying to get to I80. Thank you all so much for your input, it is greatly appreciated!!

Ditto. Quick and dirty. The shortest distance between two points is a straight line.

Just noticed a typo in my post above. It's route 28 off route 287 to get to South Pass City.

ditto to Cloud Driver's route.

Here's our favorite scenic route heading east from Yellowstone/Grand Teton.

Exit Yellowstone via the south entrance to Grand Teton NP. Stay a few days if you can, it's our favorite place. Take route 26 out of Grand Teton to Riverton then route 26/20 to I25 at Casper. Route 26 goes over the Togwotee Pass with great mountain scenery plus red rock formations further east. In early June there may still be snow at the top of the pass. An alternate would be to get off 26 north of Riverton and take route 287 to Lander. A few miles west of Lander is Sinks Canyon State Park. From Lander you can take route 789 to Riverton to join 26/20 to Casper or continue southeast on 287 to Muddy Gap and then east on route 220 to Casper. A possible side trip off 287 would be to take route 128 south to the turn off for South Pass City, then return to 287. Along route 220 you will pass Oregon Trail sites including Split Rock, Devils Gate and Independence Rock.

From Casper take I25 south and get off onto route 26 again to Guernsey for the Oregon Trail Ruts and Register Cliff. Further down 26 is Fort Laramie Historic Site. Continue on 26 past Scotts Bluff, Chimney Rock and Ash Hollow Oregon Trail sites to join with I80 at Ogalalla. We actually prefer to use route 30 eastbound from Ogalalla to avoid the heavy truck and speeding car traffic on I80.

At North Platte is the Bailey Yard of the Union Pacific RR, the largest rail yard in the world. The Golden Spike Tower there affords an elevated view of the operations.

Eastbound I would be going through the Park then east on US 26 and folow that to US 287 and south to I 80.

Agree. Just decide that you are going to enjoy that last drive through Yellowstone and the Grand Tetons and don't expect to make normal highway speeds. And be sure to look back at the Tetons from Togwotee Pass. From there on good roads and normal speed.

When we were there last Summer we departed down through the park to Moran Junction; then through Green River to Flaming Gorge (a stop for the Grandson at Dinosaur NM); then to 80.

Which direction are you going when you get to I 80?

Going west I would come down US 20 to Twin Falls and south on I 15
