The Peloponnese is a large peninsula in southern Greece, forming the southernmost part of the Balkan Peninsula. It's connected to the mainland by the Isthmus of Corinth, spanned by the Corinth Canal.
Major cities include Patras, Kalamata, and Nafplio. The region is rich in ancient sites—Olympia, Mycenae, Epidaurus—and diverse landscapes from rugged mountains to olive-groved valleys and sandy coasts.
