While the days of the Wild West seem like history to many of us, Wyoming is still a land of cowboys and ranches. Even in high-end Jackson Hole, western attire mixes with ski gear. True to that frontier spirit, it's a land perfect for exploration. The world's oldest national park, Yellowstone, brings scores of visitors to the state every year for the geothermal features and abundant wildlife. But don't miss out on the Grand Tetons, atmospheric towns like Cody and Jackson, and vast stretches of wide-open plains.
