Clinging to the northern limits of the world’s driest desert, Moquegua defies near zero annual rainfall by supporting a thriving wine industry and a valley full of green fields replete with grazing cows that look like they might have been peeled off the surface of northern France (it’s the rivers, you know). The town itself has a picturesque main square surrounded by well-preserved colonial buildings and makes a very pleasant stopover on the way to or from the southern border.
