The Corinth Canal connects the Gulf of Corinth with the Saronic Gulf in the Aegean Sea. It cuts through the narrow Isthmus of Corinth and separates the Peloponnese from the Greek mainland, arguably making the peninsula an island. The canal was dug through the Isthmus at sea level and has no locks. It is 6.4 kilometers (4 miles) in length and only 21.4 meters (70 ft) wide at its base, making it impassable for most modern ships. Nowadays it has little economic importance and is mainly a tourist attraction. The canal was initially proposed in classical times and a failed effort was made to build it in the 1st century AD. Construction started in 1881 but was hampered by geological and financial problems that bankrupted the original builders. It was completed in 1893 but, due to the canal's narrowness, navigational problems and periodic closures to repair landslides from its steep walls, it failed to attract the level of traffic expected by its operators.

According to myth, the first kings of Corinth were descendants of Sisyphus, the man who was punished by the Gods for his hubris by being forced to roll an immense boulder up a hill only for it to roll down again when they came near the top, repeating this action for eternity. Thanks to traffic and trade over the Isthmus, the narrow strip of land that connects the Peloponnese to the mainland of Greece and Attica, this ancient city, whose foundation dates back to the 10th century BC, could easily compete in terms of wealth and fame with Athens and Thebes. Until the middle of the 6th century BC Corinth's main export product were the black-figured vases, many of which made their way to several colonies in Magna Greece. The great temple on its Acropolis (the Acrocorinth) was dedicated to Aphrodite. Corinth was one of the most important cult centers for the Goddess of Love throughout its history. According to some sources, there were more than a thousand temple maidens serving,

Mycenae is an archaeological site near Mykines in Argolis, north-eastern Peloponnese, Greece. It is located about 120 kilometers (75 miles) south-west of Athens; 11 kilometers (7 miles) north of Argos; and 48 kilometers (30 miles) south of Corinth. The site is 19 kilometers (12 miles) inland from the Saronic Gulf and built upon a hill rising 900 feet above sea level. In the second millennium BC, Mycenae was one of the major centers of Greek civilization, a military stronghold which dominated much of southern Greece, Crete, the Cyclades and parts of southwest Anatolia. The period of Greek history from about 1600 BC to about 1100 BC is called Mycenaean in reference to Mycenae. At its peak in 1350 BC, the citadel and lower town had a population of 30,000 and an area of 32 hectares. The first correct identification of Mycenae in modern literature was during a survey conducted by Francesco Grimani, commissioned by the Provveditore Generale of the Kingdom of the Morea in 1700.

Nafplio is a seaport town in the Peloponnese in Greece that has expanded up the hillsides near the north end of the Argolic Gulf. The town was an important seaport held under a succession of royal houses in the Middle Ages as part of the lordship of Argos and Nafplia, held initially by the de la Roche following the Fourth Crusade before coming under the Republic of Venice and, lastly, the Ottoman Empire. The town was the capital of the First Hellenic Republic and of the Kingdom of Greece, from the start of the Greek Revolution in 1821 until 1834. Nafplio is now the capital of the regional unit of Argolis.

Tolon is a sea town, 7 kilometers (4 miles) east of Nafplion. You will enjoy your lunch at a traditional family owned restaurant enjoying the view of the Saronic gulf.
