Tarragona

Tarragona, the ancient Roman capital of Tarraco on Catalonia's southern coast, sits 100km southwest of Barcelona and is reached in about 1 hour on the Renfe Rodalies R4 or in as little as 35 minutes on the faster AVE/Avant services; driving via the AP-7 toll road takes roughly the same 1 to 1.25 hours. The city's UNESCO World Heritage Roman remains include the amphitheatre, built directly above the Mediterranean and used for gladiatorial games, along with the Roman Circus and Praetorium ruins beneath the old town, and the Passeig Arqueològic, a walkway tracing sections of the ancient city walls. Tarragona Cathedral, blending Romanesque and Gothic architecture, crowns the old town's highest point, while the Rambla Nova offers a modern promenade for a break between historic sites, and the El Serrallo fishing quarter preserves a working harbor atmosphere near the water. A typical day begins at the amphitheatre and Roman Circus in the morning, when the light over the sea is softer for photographs and the sites are less crowded, before moving to the cathedral and the Passeig Arqueològic walls walk in the afternoon. Warm-weather months from April through October suit Tarragona best, since much of the Roman archaeological area offers little shade and stone surfaces can be uncomfortably hot at midday in summer. For food, the El Serrallo fishing quarter serves fresh seafood in a more local setting than the touristy stretches near Rambla Nova, making it a good choice for a sit-down lunch after the morning's sightseeing. Beneath the amphitheatre, Platja del Miracle offers a beach break for those with extra time before the return train. Because the main Roman sites are spread across the old town with some elevation change, a full circuit involves a moderate amount of walking, and a combined archaeological sites ticket is worth buying to cover the amphitheatre, circus, and walls at a discount.
