The Group has used the dynamism of tourist mobility to develop offers and services entirely dedicated to passengers. The aim here is not only to enable them to travel around more easily, but to also to make mobility an integral part of their journey. This is how sightseeing was born, a double-decker panoramic bus trip, which provides a unique view of the city and has enabled Open Tour, the dedicated RATP Group subsidiary, to now run in Paris and London where it operates 100%-electric sightseeing buses: a world first.
