About 30–40 minutes from central Paris; arrive close to opening to avoid crowds. Palace usually opens around 9:00am (check special schedules for the gardens/fountain shows).
Visit Musée Picasso if missed or use time for boutique shopping near Marais/Opéra; check specific museum hours as many close mid-late afternoon on certain days.
