Cartagena offers an exciting array of things to do, combining ancient history, cultural treasures, and scenic seaside experiences, all within easy reach of the cruise port. Begin with a visit to the Roman Theatre, one of Spain’s most important archaeological sites, where you can explore the amphitheater and attached museum that bring 2,000 years of history to life. Just above it, hike or take the panoramic lift to Castillo de la Concepción, a medieval fortress with spectacular views over the city and harbor. Wander down Calle Mayor, the city’s main pedestrian boulevard, lined with beautifully restored Art Nouveau buildings, boutiques, cafés, and ice cream shops. Dive into maritime history at the National Museum of Underwater Archaeology (ARQUA), showcasing shipwrecked artifacts, ancient anchors, and sunken treasures. Nearby, the Naval Museum houses the prototype of the world’s first electric submarine, designed by local inventor Isaac Peral. Art and history lovers should also visit the Muralla Púnica (Punic Wall), remnants of Cartagena’s Carthaginian past, and the Civil War Shelter Museum, offering insight into Spain’s 20th-century conflicts. If you’re in the mood to relax, enjoy a walk along the Paseo Alfonso XII promenade, or unwind at Cala Cortina, a picturesque beach just a short drive from the city. Foodies can savor tapas, fresh seafood, and local specialties like caldero, a rice and fish dish traditionally cooked by fishermen. Cartagena also hosts a variety of festivals, including historical reenactments of Hannibal’s era and lively music events. Whether you’re a history buff, beachgoer, or curious wanderer, Cartagena delivers a rich, walkable, and unforgettable cultural experience.
