Spend a day exploring the historic sites and alluring villages that dot Spain's sun-soaked Mediterranean coastline. Walk in the footsteps of the Romans in the UNESCO World Heritage Site of Tarragona, and then enjoy the coastal atmosphere of the resort town of Sitges.

Meet up with your guide in the centre of Barcelona and head out of the city, travelling back in time as you cross the 2,000-year-old Devil's Bridge on your way to the port town of Tarragona. Arrive in this Roman city's UNESCO-listed historic centre and set out to explore on foot. Imagine a time when emperors and gladiators roamed these cobbled roads and listen to your guide share facts and stories about the city's past as you visit archaeological landmarks like the Roman Forum, Roman Circus, and the Roman Amphitheatre.

Continue along the coast, stopping in the quaint village of Roc de Sant Gaieta to wander among its whitewashed Mediterranean buildings. Once you arrive in laid-back Sitges, spend some time soaking up the town's beachy vibe on your own. Pick up pointers from your guide on great places to grab a bite to eat and museums and galleries that are worth a visit, or just kick back with your toes in the sand before heading back to Barcelona.
