The Utah Parks Company, a subsidiary of Union Pacific Railroad, owned and operated restaurants, lodging, and bus tours in Bryce Canyon and Zion National Parks, the north rim of Grand Canyon National Park, and Cedar Breaks National Monument from the 1920s until 1972. Operating as a concessionaire of the National Park Service, the company operated from a base in Cedar City, Utah. The company's bus tours connected there with Union Pacific trains as well as tour buses from Los Angeles, San Francisco and other west coast cities, and offered a loop tour of the region's parks and monuments, escorted by a Utah Parks Company driver/guide.
