This morning, enjoy a short city tour of the "Mile High City", including the gold-domed State Capitol whose 13th step on the west side of the building is exactly 5,280 feet above sea level - one mile high. A short distance from Denver you'll enter Rocky Mountain National Park where you'll feel like you're on top of the world. Here, 415 square miles encompass and protect spectacular mountain environments. And if you thought the journey to the park was beautiful, just wait until you experience Trail Ridge Road. Known appropriately as the "Highway to the Sky", and offering incomparable views in every direction, Trail Ridge Road winds past countless peaks, through tundra high above the treeline and crosses the Continental Divide at 12,183 feet. Continue to Cheyenne, Wyoming's capital city that embodies the spirit of the Old West. Considered the nation's railroad capital, Cheyenne is home to a collection of steam engines, including Old Number 4004, the world's largest steam locomotive and one of the eight remaining Big Boys on display throughout the country.
