Pithagorio, south across the island from Vathi, is a charming but overcrowded seaside resort built on the site of an ancient village and harbor. Although this is a convenient base for touring the southern half of Samos, the town exists primarily for the tour groups that pack its streets in the summer. We recommend staying only for a day or two to explore the nearby historic sites, then moving on to the more interesting and authentic villages of the north coast.
