.Weather CAN be a factor, because most of the park is 5,000 to 13,000' in elevation. This means a wide variation in weather from place to place, but it generally means autumn and winter are brisk.

From about October to spring (time frame varies from year to year and could be as late as May) is the snow season. It can snow 30-40 inches in a month in winter. Roads can be closed to vehicles at higher elevations, but you could get around on snowshoes or x-c skis. Some campgrounds are open in winter, but there is no water (I think the supply lines freeze).

You can check the park website for more specific open and closure info.

Great Basin is beautiful all year. In winter, there are few visitors and it is peaceful. The visitor services in town consist of a motel, grocery store, automated gas station (unstaffed but always open), and a restaurant or two. They may have limited hours or services in winter--that is, in downtown Baker. This is most of downtown Baker:

The other nearby facility is about 5 miles away, right on US 50 at the NV-UT state line. It’s a motel with restaurant and gas station—not very scenic or quaint, but your factory-built modular house will have a bed, plumbing, and a heater.

Just about anywhere in the Great Basin region (the area between the Rockies and the Sierra Nevada) can be iffy in winter. The elevations are high and the snow and wind can be wicked. Hwy 50 in both states is desolate and lightly traveled in winter. The nearest town, Ely NV, is over 60 miles mountainous miles away. Going east, Delta UT is 100 miles away. These are not "cities," but they have food, gas, and lodging. The nearest real cities are Salt Lake (250 miles) and Las Vegas (300 miles). In fact, I wouldn’t suggest coming out here just to visit Great Basin, but it would be an enjoyable side trip in connection with a trip to one of those cities. Also, before you ask, the north rim of the Grand Canyon is likely to be closed by late November,
