Here's a Recent Post on
Yellowstone & Wyoming Sites & Sights, maybe something in it will be of help.
At Cheyenne, I'd use I-25 up to Casper then west from there to Moran Junction in the Tetons north of Jackson (miss having to tread your way on somewhat narrow city streets of Jackson). Jackson is a town in the Jackson Hole valley of Teton County.
One could take advantage of the Overnighting Sites & Sights in the Douglas & Wheatland Area. Includes Guernsey & Fort Laramie Area found in the ^ above link.
As I mentioned the I-25 to Casper then US 20/26 to Moran in the Tetons, then up to Yellowstone. Thermopolis is off this route. One could go via Cody to Yellowstone as well & bypass the Tetons. More of a climb by going the Cody route. We entered via Cody once in the '90s. Came out that way in 2009.
We've gone by Thermopolis, WY twice to do a soak in the hot spring water at the State Bath House. Very neat. We overnighted in the Wind River Canyon in Aug '09 & at one of the Boysen State Park campgrounds by the lake some years ago. But each time, we had already gone to Yellowstone, before stopping.
thermopolis.com/todo/hot-springs-state-park/Easiest Route would be the South entry from Rock Springs (US 191/189) & I have heard from Rawlins (US 287) is not bad, but it takes one up to US 26 which is basically like going to Casper then over. I've heard I-80 can have fierce sidewinds at times between Cheyenne & Rawlins. But have not driven it. I-25 can also have some nice winds blowing at times as well. After all it is in the plains. Lot of rolling grassland.
We have used the US 191 and/or US 189 a few times, but we were going up from farther west than Denver. Never used the up from Rawlins route. We exited from Moran to Casper, once (with a detour to the Hot Springs) & from Cody then to Casper (with a stop at the Springs) in 2009.
The Rock Springs Route wouldn't be very reasonable for someone coming up from Houston. IMHO.
Yea! Here's an older post:
Houston to Yellowstone Question.
Lot of Sights & Sites in the above ^ link.
Basic Route would be to take I-45 N to US 287 N to Wichita Falls & onto Amarillo & Dumas. US 87 to Clayton, NM & on to I-25 N. Follow I-25 N to Casper.
Nice Rig TW,
Have a Great Trip.
