I am just travelling around northern Italy (typing this from a Milano-Torino train), and there is a visible difference between people in the Po valley and people from Como, merely 50 km apart.
People from the Po valley, such as the Milanese, are mostly "lighter Mediterranean" types. People around Como Lake are visibly more blond and pale. The ethnic substrate is different, the ancient populations in southern Alps were more Celtic and Germanic, and even though the contemporary folk no longer speaks anything but Italian, the difference to much more mixed places such as Milano is still visible.
Same in northern Spain. Galicia and Asturias have a lot of pale, blue-eyed people who would stand out in an Andalusian crowd. Galicia has Celtic ancestry (they even preserved bagpipes as a folk instrument), and Asturias was the last refuge of the Visigoths when they were crushed by the Arabs in the 8th century.
You can also easily distinguish some other European subpopulations. For example, I met a lot of Lithuanians built as a, uh, brick shithouse. Neighbouring Poles tend to be somewhat less bulky. Many Russians have a visible Tatar admixture, with broad and flat faces. Ukrainians much less so.
And you can usually tell a Greek before they open their mouths. Some of them, especially in their older age, still resemble the old beardy statues from way-before-1-AD.
