La Défense sits at the western edge of Paris at the end of the Historical Axis, a 6-mile-long (10-km) route that stretches from the Louvre, along the Champs-Elysées, past the Arc de Triomphe, and across the Seine to La Défense.
The main attraction is the Grande Arche Paris La Defense, a cube-style contemporary structure with a rooftop observation platform that provides a different view of the city. Book admission in advance to avoid waiting in the ticket line. A few city tours might include a stop or drive through La Défense but it’s not common; if you’re interested in visiting with a guide, consider booking a private tour.
