Greyhound buses operate along I-80 through the south. The rest of the state is covered only patchily by regional bus companies; it takes considerable time and planning to get where you want to go, so your own car is definitely the best option. Jackson has the state's largest airport, though flights also go to Casper and Cheyenne. Cycling across northern Wyoming can be great fun, although if you're crossing the Bighorns you'll need to pick your routes carefully, as roads here have incredibly steep gradients. Northern Wyoming is the prime tourist goal, with well over three million per year heading for the simmering geothermal landscape of Yellowstone National Park, and the craggy mountain vistas of the adjacent, and equally outstanding, Grand Teton National Park. Wedged in between Yellowstone and South Dakota to the east are the helter-skelter Bighorn Mountains, likeable Old West towns such as Buffalo, and the otherworldly outcrop of Devils Tower.

Information for the visitor to Wyoming, WY, United States
The classic triangular peaks of GRAND TETON NATIONAL PARK , which stretches for fifty miles between Yellowstone and Jackson, are every bit as dramatic as the mountains of its congested neighbor, and a visit should be more than an afterthought on the route south. Though not especially high or extensive by Rocky Mountain standards, these sheer-faced cliffs make a magnificent spectacle, rising abruptly to tower 7000ft above the valley floor. A string of gem-like lakes is set tight at the foot of the mountains; beyond them lies the broad, sagebrush-covered Jackson Hole (a "hole" was the pioneers' term for a flat, mountain-ringed valley), broken by the winding Snake River.
Northern Wyoming has a lot more to offer than just a handy route between the Black Hills and Yellowstone. The surreal volcanic monument of Devils Tower, the abrupt Bighorn Mountains and the desertscape of the Bighorn Basin are the major natural attractions in a land steeped in the history of Native American wars, outlaw activity and pioneer hardships. Small towns such as unassuming Buffalo and the more commercialized Cody, developed by Buffalo Bill himself, are potential stopovers.
State capital Cheyenne is the only town of real note in the lower two-thirds of Wyoming. Set in the heart of rich prairie - a surprise after the scrubland, mountain and desert of most of the region - it has closer economic ties with Omaha or Denver than with the rest of Wyoming, a point the more northerly oil city of Casper stressed in its unsuccessful bids to become the seat of government. West of Cheyenne, smaller Laramie possesses an agreeable frontier feel, while the spectacular wilderness of the Wind River Range, accessible from Pinedale and Lander, accounts for most of the west central portion of the state.
Millions of visitors each year come to YELLOWSTONE NATIONAL PARK, America's oldest national park and the largest in the lower 48 states, to glory in its magnificent mountain scenery and abundant wildlife, and above all to witness hydrothermal phenomena on a unique scale. Measuring roughly sixty by fifty miles, and overlapping slightly from Wyoming's northwestern corner into Idaho and Montana, the park centers on a 7500ft-high plateau, the caldera of a vast volcanic eruption that occurred a mere 600,000 years ago. Into it are crammed more than half the world's geysers, in which the rain and snow that seep through the bedrock escape the pressure-cooker conditions under the surface in intermittent spectacular blasts, plus thousands of fumaroles jetting plumes of steam, mud pots gurgling with acid-dissolved muds and clays, and hot springs .
Yellowstone amounts to an extraordinary experience, combining the colors of the Grand Canyon of the Yellowstone, limpid Yellowstone Lake, the wild flower meadows and the rainbow-hued geyser pools; the sounds of subterranean rumblings, belching mud pools, and steam hissing from the mountainsides; and the constant smells of drifting sulphurous fumes, with the presence of browsing bull moose, shambling bears, heavy-bearded bison, herds of elk and ubiquitous scurrying marmots . It is, however, very popular; if you let yourself get frustrated by the inevitable crowds and expense, you risk missing something very special. The key to appreciating the park is to take your time, and to plan carefully; above all, try to allow for a stay of at least three days.
Touring the park
All of Yellowstone's major sights are labeled and signposted within a few hundred yards of the 142-mile Loop Road, a figure-of-eight circuit fed by roads from the five entrances.
