Big Bus Tours is the world’s largest operator of open-top sightseeing tours, inspiring the spirit of adventure in 25+ world-famous cities across four continents. Beginning its journey with a fleet of only three buses, Big Bus Tours has swiftly expanded to a global fleet of hundreds of open-top buses, turning millions of tourists into explorers, every year. With a sightseeing concept designed to provide a flexible approach to city discovery, each open-top bus tour provides a hop-on, hop-off facility at a variety of interesting locations, with complimentary additions to enhance the visitor sightseeing experience. In February 2015, private equity firm Exponent purchased Big Bus Tours, with a shared vision to make Big Bus Tours the number 1 thing to do in each world-famous city. In 2016, Merlin Entertainments PLC became a shareholder, offering a natural synergy with Big Bus Tours and Merlin attractions and experiences around the world. With entertaining audio guides and knowledge of the latest events in each city, the Big Bus experience leaves every passenger with a story to tell. A perfect city companion, The Big Bus Tours app includes tour highlights, city guides and map and real-time bus tracking, downloadable in the Apple and Android App stores.
