Scenic Routes/Places to See in WY, ID, MT, SD & E. CO

There's much more to see at Rapid City beside Mt Rushmore,the badlands, hill City Dinosaur dig,Lead, Sturgis. A side trip to Devils Tower In WY.
Cody as a great museum.

Several favorites we have enjoyed over the years: (1) MT 509 from Henry's Lake, ID west to Monida, MT in the Red Rocks Country, (2) MT 278 and MT 43 from Bannack northwest to Chief Joseph Pass thru the Big Hole Country, (3) US 12 from Lolo, MT westward to Lewiston, ID along the Lewis & Clark Highway and the Lochsa and Clearwater Rivers. Good camping spots along US 12, stop at the visitor center on Lolo Pass for more info.

When you say "Eastern" Colorado, how east are we talking? Actual Eastern CO doesn't have a whole lot of scenic anything as it's all flat and farming/ranching.

In WY there's too much to list... depends on your route.

Tyler0215, Islandman, thanks for your input! Much appreciated.

JAC1982, we look at I25 as the east/west division point for CO. We've given some thought to visiting Pikes Peak. That's about as far west (into CO) as we want to go on this trip.

Island Park, ID can be a good base camp for at least some of Yellowstone (about 15-25 miles from the west gate of the park, depending where in Island Park you land). From there you can also spend 1/2 day or so at Mesa Falls (beautiful)! and even head up to Virginia City MT - old mining town - or Hebgen Lake area (Quake Lake, etc.) Or south from there to the Tetons, via either ID 33 or (better route for RVs) US 26 - longer drive but pretty. Definitely you'd need reservations in the Tetons unless you can dry camp.

Craters of the Moon NP is a neat little park, and very different. You can camp there (hot & you have to dry camp) or base camp in Arco ID, about 20 miles east of the park; on US 20.

ID 12 from Lolo Pass south is a fav of ours. We always camp at USFS CG Powell. Any road in Idaho is pretty hard to beat. Enjoy. Betsy.

The area around Dubois, WYO is great. Not crowded as everyone goes onto Jackson Hole. Several nice USFS CGs NW towards Moran but stay on east side of Continental Divide to avoid crowds. Spectacular rugged snow-capped peaks, good fishing, and mosquitos the size of bumble bees until September. Should be okay then. Enjoy!!
There are a couple of nice RV parks in Dubois.

Sitting Bull Campground in Bighorn NF is beautiful and lots of bear and moose around. That entire area is worth a visit.
