Lisbon rises over the Tagus on a tangle of hills best explored on foot and by the rattling Tram 28. Wander the medieval Alfama, where fado drifts from tiny bars, and climb to the miradouros for sweeping views.
In Belém, the Age of Discovery lives on in the Jerónimos Monastery and the riverside tower — and in the original pastéis de nata, still baked to a secret recipe.
Lisbon is affordable, sunny and endlessly photogenic, an easy city to fall for over a long weekend.
