On your second day, dive into the cultural offerings of Parc de la Villette. Visit the Cité des Sciences et de l'Industrie, a science museum that offers interactive exhibits on various scientific topics. Explore the Explora exhibitions, which cover subjects like space, biology, and technology. Don't miss the impressive Géode, a giant silver sphere that houses a cinema with a giant screen. Afterward, head to the Cité de la Musique, a museum dedicated to music. Discover the history of music through its extensive collection of instruments, manuscripts, and audiovisual archives. If you're lucky, you might even catch a live performance or a workshop. In the evening, enjoy a meal at one of the park's many restaurants or cafes, and take a leisurely stroll along the canals to soak in the atmosphere.
