Since 1910, Gray Line has grown into the most well-known consumer brand in sightseeing tours. Its global network of elite providers operates day tours, airport transfers, hop-on hop-off tours, multi-day packages, walking tours and other specialized destination services.


In March 1910, a young restaurateur by the name of Louis Bush refurbished an old Mack Truck chassis, painted it blue and gray and began offering sightseeing tours around the city of Washington, D.C. Little did he know, his earnest endeavors would help establish the world's leading sightseeing tour company, known today as Gray Line.

By 1926, Gray Line had expanded to other booming cities including New York, Chicago, Detroit, New Orleans, Los Angeles, San Francisco, as well as internationally to Toronto and Havana. With peacetime following World War II, Harry J. Dooley, a former Gray Line employee, acquired the company and helped re-establish Gray Line Chicago. Dooley soon became president of Gray Line and is today considered the father of the sightseeing industry.

With the advent of jet travel and increased gateways in the late 1940s and early 1950s, Dooley expanded Gray Line's market throughout the United States and established Gray Line companies in Canada, Mexico, Hawaii and Puerto Rico. The sudden popularity growth in motorcoach sightseeing helped position Gray Line as the leader in the sightseeing industry for decades to follow.

The brand is currently managed from an office based in Denver, Colorado.

Gray Line has a presence in over 700 locations, spanning six continents, and is the largest sightseeing company in the world. In 2018 its carriers handled over 35 million passengers.
