Wyoming's geography includes wide-open plains, swaths of high desert and sweeping mountain ranges. To help visitors get oriented and navigate around, the Wyoming Office of Tourism divides the state into five distinct regions: Wyoming is a great place to discover the American West at affordable prices while also visiting what is considered to be a US tax haven state. With many unspoiled mountain vistas, vast blue skies and the awe-inspiring scenery of the high plains and Rocky Mountains, Wyoming offers much of what travelers to this region seek. Unlike other states in the Rockies, Wyoming's demographic growth has been restricted to a few areas of the state where mineral extraction has expanded in the recent past. While mining and drilling have expanded recently (and very notably in some regions), Wyoming is still relatively unspoiled compared to other parts of the region. Wyoming is the least populated U.S. state, with slightly more than half a million residents, the majority of whom cluster into a handfull of cities and towns. Of these, Cheyenne and Casper are the largest and are home to more than a quarter of the state's citizens. For visitors, this means that the distance between towns is often vast, requiring more planning and self-sufficiency than travel in more densely populated parts of the country. It also means that travelers will have the chance to experience first hand the feeling of being all alone in vast, wide-open spaces.
