Known for its wide-open skies, cowboy culture, and massive expanses of farmland and wilderness, and with all that open road, it's a perfect destination for RV exploration. Montana is definitely a summer destination, particularly if you plan to drive over the Continental Divide on Glacier National Park’s Going-to-the-Sun Road, which is only open seasonally (overhangs make this famous road unsuitable for larger RVs). The shoulder seasons are also great for visiting, with multi-hued wildflowers galore in late spring and colorful fall foliage in the autumn months, while winter is great for cross country skiing and soaking it up in the state's many Hot Springs. Most visitors make a point of spending time in and around Yellowstone National Park, and while RV sites inside the park often fill up well in advance, there are tons of options—many with full hookups, wifi, clubhouses, and more—within a quick drive of the park’s north entrance.
