Havana packs centuries of history into a compact, walkable core, making a short visit surprisingly rewarding if you prioritize well. Old Havana (Habana Vieja) is the natural starting point, its colonial streets opening onto Plaza de la Catedral and the baroque facade of Catedral de La Habana. From there, the grand dome of El Capitolio Nacional showcases the city's early twentieth-century ambition, while a sunset walk along the Malecón Boardwalk captures Havana's atmosphere better than any museum. Across the harbor, Fortaleza de San Carlos de la Cabaña rewards the climb with sweeping views and a glimpse of colonial defense. Together these sites cover Havana's essential character in a single, unhurried day.
