Take a full-day excursion to Tarragona and Sitges and combine a tour of the Roman city with an afternoon lazing on the beach. The 11-hour trip departs from Barcelona and heads south to Tarragona’s breathtaking 2,000-year-old Roman Aqueduct, known locally as El Pont del Diable (The Devil’s Bridge). The perfectly preserved piece of ancient Roman history is hardly ever visited by tourists, but leaves an indelible impression on all who see it. From the Aqueduct, travel into Tarragona city center and explore the ancient Roman capital of the Iberian Peninsula, entering the Old Town through a narrow gateway in the Roman walls. Starting at the Archaeological Walkway, admire the surviving stone walls, wander through the historic old quarter, pass the medieval hospital, and stop at the cathedral to enjoy the Sunday morning antique market for a great chance to pick up some unique gifts.
