Braga is Portugal's most underrated city — older than Lisbon, with more churches per square kilometre than anywhere in the country, a thriving student population that has transformed the food and nightlife scene over the past decade, and prices that make it the best-value city in mainland Portugal. The Bom Jesus do Monte sanctuary — a baroque staircase of 577 steps climbing the hill above the city, with chapels representing the Via Crucis at each landing — is one of the most beautiful architectural approaches to any building in Portugal and gave Braga the name "the Rome of Portugal". An hour from Porto by train and completely free of the tourist pressure that has made Porto increasingly difficult to navigate.
From London it's 90 minutes to Porto (easyJet, Ryanair) plus a 50-minute train to Braga (€6.20) — a practical combination with a Porto day trip. Alternatively, direct Ryanair services to Porto from Manchester, Edinburgh and other UK regional airports. Braga has no airport of its own. Go from April to October: the Semana Santa (Holy Week) processions through the baroque streets are among the most dramatic in the Iberian peninsula. The student festival Festas de São João in June is the most vibrant week of the year.
