Big Bus Tours is the largest operator of open-top sightseeing tours in the world, providing sightseeing tours in 20 cities across three continents.

It was formed by the merger of two established sightseeing tour businesses: the Big Bus Company Ltd (based in London) and Les Cars Rouges (based in Paris). The two businesses, each with over 20 years of successful tour experience, created Big Bus Tours in May 2011. Big Bus was purchased by Exponent LLC a London based private equity partnership in 2015. The Big Bus philosophy is to ‘think global and act local’. “Understanding each city, its character and culture as well as its landmarks is key to our success” commented Pat Waterman, CEO. “We aim to provide exceptional levels of service and a unique sightseeing experience to the millions of customers we receive” every year.
