15 Best Sights in Cody, Sheridan, and Northern Wyoming, Wyoming

This extraordinary "five-in-one" complex, an affiliate of the Smithsonian Institution, contains the Buffalo Bill Museum, the Whitney Western Art Museum, the Plains Indian Museum, the Cody Firearms Museum, and the Draper Natural History Museum. All are well organized and mount superb exhibitions in their respective subject areas. The flagship Buffalo Bill Museum puts into context the life, era, and activities of its (and its town's) namesake, William F. “Buffalo Bill” Cody (1846–1917), whose numerous careers included guide, scout, actor, and entrepreneur. If you want to understand how the myth of the American West developed, this is the place to come. The other four museums—there's also a research library—are equally absorbing. Plan to spend at least four hours here—and to discover that this isn't enough time to take it all in. Luckily, your admission ticket is good for two consecutive days.

In 1877 a few members of the Nez Perce tribe killed some white settlers in Idaho as retribution for earlier killings by whites. Fearing that the U.S. Army would punish the guilty and innocent alike, hundreds of Nez Perce fled on a five-month journey toward Canada along what came to be known as the Nez Perce Trail. On the way they passed through what is now Yellowstone National Park, across the Sunlight Basin area north of Cody, and along the Clarks Fork of the Shoshone River before turning north into Montana. To see the rugged mountain area they traveled through, follow Highway 120 north 17 miles to Highway 296, the Chief Joseph Scenic Highway. The highway twists and turns for 46 miles, ending at similarly stunning U.S. 212, the Beartooth Scenic Highway, which leads west to the pretty hamlet of Cooke City, Montana and then the Northeast Entrance of Yellowstone, or east to the small ski and hiking hub of Red Lodge. Along the way you'll see open meadows, pine forests, and a sweeping vista of the region from the top of Dead Indian Pass.

Begun in 1938 and billing itself the world's longest-running nightly rodeo, this festive, family-friendly summer spectacle at Stampede Park is less flashy and more endearingly intimate than bigger rodeos around the region, such as Cheyenne Frontier Days. Kicking off at 8 pm each evening from June through August, the Cody Nite Rodeo offers kids' competitions, such as goat roping and junior barrel racing, in addition to the regular adult events. Over early July's Independence Day weekend, the annual Cody Stampede features a full long weekend of events at the same venue.

As you drive east from Gillette, the highways begin to rise into the forested slopes of the Black Hills. A detour north will take you to Devils Tower. Geologists attribute the butte's strange existence to ancient volcanic activity. Rock climbers say it's one of the best crack-climbing areas on the continent. The tower was a tourist magnet long before a spaceship landed here in the movie Close Encounters of the Third Kind. Teddy Roosevelt made it the nation's first national monument in 1906, and it has attracted a steadily increasing throng of visitors ever since—up to nearly half a million people a year.

When you visit, take some time to stop at the visitor center. Exhibits here explain the geology, history, and cultural significance of the monument, and a bookstore carries a wide selection of materials relating to the park. Park rangers can provide updated information on hiking and climbing conditions. A short and easy walking path circles the tower.

The land that became Wyoming's first state park in 1897 had always been sacred to Native Americans because of its healing natural hot springs. You can partake of these waters by soaking indoors or outside at the free 104°F mineral pools at the State Bath House, which is a central feature of this impressive 1,104-acre park that's also home to two waterparks (which charge admission fees) with more indoor and outdoor hot mineral pools, waterslides, and other amusements. You can also hike or bike on 6 miles of trails, view the park's sizable bison herd, traipse across a swinging suspension bridge that traverses the Big Horn River, offering views of the dramatic travertine mineral terraces.

The Jim Gatchell Memorial Museum is the kind of small-town museum that's worth stopping for if you're interested in the frontier history of the region, including the Johnson County Cattle War. It contains Native American, military, outlaw, and ranching artifacts collected by a local pharmacist who was a close friend of area Native Americans. The museum completed a $300,000 renovation project in 2011. Visitors will discover new exhibits and interpretive opportunities.

A ring of rocks 75 feet in diameter, this ancient site is the best preserved of nearly 150 Native American stone wheels found in Wyoming, South Dakota, Montana, Alberta, and Saskatchewan. Evidence such as the 28 spokes (one for each day of the lunar cycle) leading from the edge of the wheel to a central cairn has persuaded some that the wheel was an ancient spiritual observatory much like England's Stonehenge may have been. To protect the area, access to the wheel is restricted to foot travel; it's a 1½-mile hike on a well-maintained unpaved road to the site from the parking lot (people with disabilities may drive to the site). Up in the Big Horn Mountains, at an elevation of 9,642 feet, the site affords views of the entire Big Horn Basin. Dress warmly, as it's cool up here, even in summer.

Five major immigrant trails passed near or through Casper between 1843 and 1870. The best-known are the Oregon Trail and the Mormon Trail, both of which crossed the North Platte River in the vicinity of today's Casper. The National Historic Trails Interpretive Center examines the early history of the trails and the military's role in central Wyoming. Projected onto a series of screens 11 feet high and 55 feet wide, a film shows Wyoming trail sites and scenes of wagon travelers. You can climb into a wagon to see what it was like to cross the river, or learn about Mormon pioneers who traveled west with handcarts in 1856.

Evidence of the area's old-world ties can be found at the Sheridan Inn, just a few blocks from downtown near the old railroad depot. Modeled after a hunting lodge in Scotland, the 1893 building sports 69 gables in a show of architectural splendor not often seen around these parts. On the National Register of Historic Places, the inn once lured the likes of Herbert Hoover, Will Rogers, and Ernest Hemingway, and Buffalo Bill auditioned performers here for his Wild West Show. The Inn underwent a $4.8 million restoration from 2006 to 2009, employing "green" technologies, and an additional $2.8 million was spent in 2010 to refurbish the 22 guest rooms. The original Buffalo Bill Bar, an oak-and-mahogany monstrosity on the main floor, is purported to be a gift sent from England by Queen Victoria.

Casper College's Tate Geological Museum in the Tate Earth Science Center displays fossils, rocks, jade, and the fossilized remains of a brontosaurus, plus other dinosaur bones. The centerpiece for the Tate is Dee, an 11,600-year-old Columbian Mammoth. Dee is one of the largest complete Columbian Mammoths ever discovered.

Among the nearly 60 dinosaur skeletons displayed at this nonprofit museum and research center is the winged "Thermopolis Specimen," the only Archaeopteryx exhibited outside of Europe, and "Stan," one of the most complete Tyrannosaurus rex skeletons in the world, measuring 35 feet long and weighing in at nearly 6 tons. Special full-day programs allow kids and adults to try their hand at paleontology by digging in one of the several active dinosaur sites nearby (some 10,000 dinosaur bones have been excavated in the vicinity since 1993). Tours of the dig site are also offered daily in summer.
