BIGBUS is the world's largest operator of open-top sightseeing bus tours. The famous BIGBUS double-decker buses have a fleet that is mostly electric and offer a complete tour to discover the iconic monuments of Paris. 

BIGBUS has been a partner of BATOBUS since 2025, with an offer—the DUO LIBERTÉ Pass—that allows full enjoyment of our two hop-on hop-off services on land and on the Seine.
