Mendoubia Gardens sit just west of the Grand Socco, making them an easy pause between Tangier's new town and the medina. The garden has shaded paths, benches, old trees, and a large marble fountain, with enough local life around it to feel like part of the city rather than a formal show garden.
It is best treated as a short stop while walking the central sights, especially if you want a quieter break before entering the busier lanes of the medina.
