The 20th keeps its village heights better than any other arrondissement, and La Campagne à Paris is the proof: three cobbled lanes of brick cottages on a hill, built in the 1920s so working families could own a house with a garden. It still looks like a film set, except the people are real.
Start at Porte de Bagnolet and climb the steps into the village. Walk all three streets — they take ten minutes and reward every one. Then drop off the hill down rue de la Mare, a steep old lane that follows a vanished stream, to the medieval church of Saint-Germain de Charonne and its sloping graveyard, one of only two parish churchyards left inside the walls.
From the church, the cobbled rue Saint-Blaise runs downhill through the old village core. Then cut to the Jardin naturel by the wall of Père-Lachaise — a garden the city has let run wild on purpose. You don't have to linger, but you'll want to.
End at place Gambetta and the M3 — or walk straight on into the cemetery.
