This is the walk where Lisbon's two faces meet on one hill: the castle that crowns the city and the Mouraria that crowds beneath it. You climb to the view, then come down into the quarter that has absorbed everyone the city ever sent its way.
Three kilometres, a loop. Start at Martim Moniz — the loudest, most mixed square in Lisbon — and get the steep part over while the morning's cool. The Castelo de São Jorge is the summit and the postcard: ramparts, peacocks, and the entire city poured out below to the river. Walk the walls before the crowds and the heat arrive.
Then down. Past Largo das Portas do Sol for one last river view, and inland into the Mouraria — the ground the Moors were moved to after the 1147 reconquest, and the most diverse quarter in the city ever since. The lanes are thick with murals and cooking smells; fado (the music) was born here too. Climb to Largo do Intendente, once notorious, now all tiled façades and cafés.
Back to Martim Moniz for the metro, and lunch from half the world within one block.
