Catch a train from Tarragona to beautiful Barcelona, one of Spain’s most famous cities. The ride itself is just over an hour and often costs around 10 euros, leaving you plenty of time to explore the best things to do in Barcelona before returning to port. Some of the most iconic sights include La Sagrada Familia, bustling La Rambla, and the city’s historic Gothic Quarter.
Is looking out at the ocean not enough for you? Dip your toes into the golden sands of Costa Dorada. El Miracle beach is the liveliest and closest to the city center, while the beautifully isolated Cala Fonda, just several miles north, evokes the Balearic islands that sit far off Tarragona's shores.
