About Gray Line

Gray Line is a provider of sightseeing tours, activities, attraction tickets and in-destination transportation, etc. The company was founded more than 100 years ago. 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 helped establish the world's leading sightseeing tour company, known today as Gray Line. Today the company has more than 700 destinations on six continents to offer and show them to its clients. It provides around 4,000 tours and activities. Gray Line is currently based in Denver, Colorado.
