Right below the famous Temple of Sounion there is a small cove with a sandy beach, two great tavernas and the Hotel Aegeon which is right on the beach. If you are taking a day trip to Sounion bring your bathing suits and your appetite. The beach is actually much nicer than this photo. Probably the closest to being on an island because actually it is the closest beach to the islands. You can take the orange KTEL bus from Pedion Areos or Syntagma and it leaves every half hour and takes about 90 minutes.
