Those of us here out West are mostly spoiled with the various styes of riding we have available out here. As others have mentioned, depending on what you desire for style of riding will determine where you go. While there are trails out here, most often the trails are for tours and tourists who want to see the splendor of the Rocky Mountains in wintertime and get that feeling of being out in the cold so it feels awesome to come back in from the cold.
We don't really have the lake stuff that the Midwest has. We have everything else from steep aggressive chutes, tight trees all the way to wide open powder meadows that rarely see greater than 30* slopes. My preference is the latter. I'm not picky, however I do prefer 18-36" of new snow on a bluebird day in the meadows so I can ride my sled like I was riding a sea-doo on water, gliding on top of the powder.

Reason being? It hurts less when I fall.
As most visitors will try to get accommodations close to the areas they will be riding, distance won't be as much a concern for you than us. While we will look to do a overnight or two, most just drive from home the day of. As expected, there are usually rooms or AirBNB available near great spots. A few with ride-in and ride-out accessibility.
If you want a good combo of trails and meadows in Colorado, Grand Lake has lots of both. They get good snow, and for most of the season sleds are allowed on the streets in town.
Grand Mesa is fantastic, and usually gets tons of snow. There are places to stay very near the Mesa, but they are usually pretty booked.
I am hoping to get my first shot at the Snowy Range (In Wyoming) this winter. That general area between Northern Colorado and Southern Wyoming can get some very decent snow totals and have lots of similar terrain. That includes most of the stuff I mentioned earlier.
For the hardcore folks, north of Colorado has the most. Colorado does have its fair share, but nothing like Wyoming north.
Due to the terrain, it is usually after the holidays when the snow starts to be the best and can continue through April.
