Marina Eleusis

Marina Eleusis sits in the Saronic Gulf just outside Athens, open year-round and backed by one of Greece's most historically significant cities — Eleusis, home to the ancient Eleusinian Mysteries and a 3,400-year-old story. You get solid modern facilities for your boat alongside easy access to archaeological sites that most people only read about in history books. It's the kind of stop where you end up staying longer than planned.
