West Glacier MT to Devils Tower WY

There's a decent KOA about 50 yards from the entrance to Devil's Tower. Next door to a trading post/souvenir shop/cafe. I think they still show "Close Encounters" every night in the Trading Post.

Two nice R V parks at Buffalo. Watch for pronghorn everywhere.

Thanks Desert Hawk for all the info. We will check our route and may modify it. We do have to travel on Hwy 2 to 93 to Missola but then we have a long time on I90.

Morning all, We will be traveling I90 from West Glacier to Devils Tower. Any suggestion on good rv parks to stop at? Also any must see's along the way? Thanks for any suggestions. Safe travels.

If you're talking about West Glacier, MT, that's on Highway 2, not I-90. You would have to go west to Kalispell to Highway 93 and drop south to I-90.

A short detour from the Route: East of Billings on I-94, we drove by Pompey's Pillar not knowing what it was in 2009, about 25 miles east of Billings, Montana, on our way to Yellowstone. "It bears the only remaining physical evidence of the Lewis and Clark Expedition, which appears on the trail today as it did 200 years ago. On the face of the 150-foot butte, Captain William Clark carved his name on July 25, 1806, during his return to the United States through the beautiful Yellowstone Valley." Might be worth a stop, if time allows.

On 1-90 between Billings & Sheridan, Little Bighorn Battlefield Nat'l Mon't has a special place in history. Not far from Sheridan.

Also off I-90 in WY, The Site of the Fetterman Fight and Fort Phil Kearny.

One would have to leave I-90 at Buffalo, WY & use I-25 S to see these. Just in case I'll add:

Overnighting Sites & Sights in the Douglas & Wheatland Area. Includes Guernsey & Fort Laramie Area.

Guernsey State Park ------- Fort Laramie National Historic Site ------ Oregon Trail Ruts and Register Cliff

From This Area:
One can use WY 59 N from Douglas to Gallette to return to I-90. A very nice hwy. Many supper long coal trains along it, Bison often seen in places by the roadway & open pit coal mines off in the distance. Coal mines & Trains reason for the good roadway.

Or use US 85 N from the Lusk or the Lingle Area to Newcastle; US 16 to I-90 (Keyhole State Park) & US 14 which runs up to Devil's Tower.
Keyhole

Very long detour, but some neat sights & sites (the above tour).

A detour by Sheridan:
We drove up & over the Big Horns from Sheridan on US 14 & took the 14 A down (a very steep descent & one I wouldn't want to do again). BighornMountains.Com

We passed the turn off to Medicine Wheel, but didn't go see it, on 14 A. I've wanted to see the site. 14 A was too bad yet by this turn off. Not for an RV.

Years ago, we did a layover in Buffalo (trouble with the pickup) one sunday & an overnight. We rode our bikes around the town, went to a museum & by a city swimming pool. Things to do in Buffalo

US 14 & 14 A Video US 14 A was a harry drive, extremely steep. Video: US 14 A I believe the steepest parts are after the Medicine Wheel exit.
