Step inside the Fondation Louis Vuitton, Frank Gehry's striking glass-and-steel landmark in the Bois de Boulogne, and spend your visit moving freely through its sail-shaped pavilions. Skip-the-line entry means you head straight into the galleries, where rotating exhibitions of modern and contemporary art unfold across bright, naturally lit spaces. Take your time tracing the building's curves from both sides, the cascading glass "sails" overhead inside, and the sculptural exterior set against the trees outside. Climb up to the terraces for sweeping views over the park and the Paris skyline, a highlight many visitors say rivals the art itself. Whether you're drawn in by the architecture, the exhibitions, or simply the chance to wander an iconic cultural landmark at your own pace, this is a calm, self-guided way to experience one of the city's most photographed buildings from the inside.
