Estes Park / Yellowstone / Grand Teton Trip

The road Bill Satellite describes is the Wind River Canyon Scenic Byway and I completely agree on how gorgeous it is. I always try to send visitors to the state that way. The tunnels look scary but it is a U.S. highway and sized for semis so you won't have any problem in your Class A. (The first timee I drove my then-Class-C through it, I called the state highway patrol first to make sure the tunnels had enough clearance!)

Another gorgeous spot more-or-less on your route is the Snowy Range Scenic Byway. Twisty turny and some fairly steep bits but I've been over it in both a Class C and an underpowered Class A. There was still snow up there when we went over on July 4. The "hobo" hot pool/springs in Saratoga are free and VERY hot - I can't do the pool.

The road from I-25 to Estes is another U.S. highway and I strongly urge you to plan to drive it in full daylight. First, because it is gorgeous and second, because there are some VERY twisty turny bits and you want all the visibility you can get. Daylight gets blocked by the mountains earlier than you would expect.

I've done Yellowstone in a MH with no toad. There was one road I chickened out of driving in the class C but there is so much to see that it's not like we suffered from missing that one area. Old Faithful is completely accessible to motorhomes - tons of parking.

If you stop in Jackson, expect to spend 3x the amount of money for anything. Too many rich people there.

Plan for no cell coverage oftener than you want. I was steered to a program called Maps.ME that is designed to work with no data coverage, you download the state maps ahead of time and it works off GPS. Works pretty well in my car, I haven't tried it in a MH yet but planning to have it handy for the eclipse (to hunt for alternate routes if the traffic is as bad as expected).

You should find this article to be helpful. It describes the various routes in and out of the park and recommends some places to stay.

Another tourist trap that many miss is Virginia City,MT. Take the narrow gauge RR from Virginia City to Nevada City,MT. Nevada City has one of the largest collections of self player instruments in the country. Touring the old time town is a hoot. Allow 1 day. Approx. 87 miles NW of West Yellowstone,MT.
When we travel to Yellowstone, we stay at Henry's Lake State Park, ID. Good rates. Great view. 15 miles west of the west gate.

A big X2 on what Bill.Satellite suggests. Been there done that.

Many folks miss Cody, WY while in, or on their way to, Yellowstone. The museum there is not to be missed and needs at least 1 full day but 2 days is better. Thermopolis is also a fun stop but the drive leading up to Thermopois on 26/120 is one of the greatest drives I have ever taken. We had no idea there was such spectacular scenery and we were completely blown away. We stayed at an RV park with there own hot spring and really enjoyed our overnight stay. So, 25 N to Casper, 26 to Thermopolis, and 120 up to Cody. It's then 14W into Yellowstone's West Entrance.

We have traveled to all three of these locations and enjoyed them very much.

Will you be towing a car? The reason I ask is that many of the sights, especially in Yellowstone are very limited as to access for Class A motorhomes. The roads in Yellowstone tend to be somewhat narrow and at the 'choke points'- any place animals have been spotted - the traffic flow is stop and go and single lane.

Many of the turn-out areas are limited in size and maneuvering any motorhome, let alone a Class A is sketchy.

Don't let these comments stop you from going to Yellowstone, just beware of the potential problems.

Have fun.
