Those looking for something to do in Montana probably won't have to wait in any lines. The state isn’t just one of the country's largest, it’s also one of its least-densely populated, and boasts a vast, rugged landscape little changed since Lewis and Clark passed through in 1805.

Any guide to Montana would undoubtedly begin with a list of must-see sites in the great outdoors. Inside Glacier National Park, the aptly named Going-to-the-Sun Road cuts across the Continental Divide, revealing panoramic views of Rocky Mountain peaks, alpine meadows, and crystalline lakes. On Montana's southern border, Yellowstone National Park unfolds into 2.2 million acres of wilderness. Here, visitors can watch geysers leap into the sky and spy the Lower Falls waterfall as it topples 308 feet downwards into the Grand Canyon of the Yellowstone.

While many would be content to simply gaze into the state’s scenic landscape, there are many more active things to do in Montana. At Hawley Mountain Guest Ranch, guests channel their inner cowboys while horseback riding through the mountains, fly fishing in the Boulder River, and chowing down at a campfire cookout. Known for its powdery slopes, the Bridger Bowl ski resort in Bozeman is a popular spot for winter sports. And if you want to warm up, head to the Potosi Hot Springs Resort in the Tobacco Mountains, for a soak in one of two pure mineral thermal springs.

There's more to soak up than just nature, though. The Little Bighorn Battlefield National Monument memorializes the battle famously known as "Custer's Last Stand," while the Old No. 1 Trolley in Butte whisks passengers on tours of the town's colorful gold mining past. Looking for nightlife? Forget the theater and head to the Butte Vigilante Rodeo, for some bull riding, calf roping, and rodeo clowns instead.
