Ancient Corinth, Epidaurus, Nafplio private tour from Athens

The Corinth Canal connects the Gulf of Corinth in the Ionian Sea 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 kilometres (4 mi) in length and only 21.4 metres (70 ft) wide at its base, making it impassable for many modern ships.
From high up, you can enjoy the best view of Corinth's isthmus and admire the steep limestone walls while you observe the vessels below you navigate their way through the canal.

Corinth was a city-state on the Isthmus of Corinth, the narrow stretch of land that joins the Peloponnese to the mainland of Greece, roughly halfway between Athens and Sparta. The modern city of Corinth is located approximately 5 kilometres (3.1 mi) northeast of the ancient ruins.
For Christians, Corinth is well known from the two letters of Saint Paul in the New Testament, First and Second Corinthians. Corinth is also mentioned in the Acts of the Apostles as part of Paul the Apostle's missionary travels. In addition, the second book of Pausanias' Description of Greece is devoted to Corinth.
Ancient Corinth was one of the largest and most important cities of Greece, with a population of 90,000 in 400 BC. The Romans demolished Corinth in 146 BC, built a new city in its place in 44 BC, and later made it the provincial capital of Greece.

The Archaeological Museum of Ancient Corinth was constructed between 1931-1932, with intentions to display the numerous recent archaeological excavations. The museum is located within the archaeological site of Ancient Corinth, Greece, and lies under the jurisdiction of the 37th Ephoreia of the Greek Archaeological Service.
Key aspects of the Archaeological site of Ancient Corinth include:
Hadgimoustafa spring

The Temple of Apollo at Corinth was constructed in 550 BC.

Acrocorinth, "Upper Corinth", the acropolis of ancient Corinth, is a monolithic rock overseeing the ancient city of Corinth, Greece.
With its secure water supply, Acrocorinth's fortress was repeatedly used as a last line of defense in southern Greece because it commanded the Isthmus of Corinth, repelling foes from entry by land into the Peloponnese peninsula.

Archaeological Museum of Epidaurus is a museum in Epidaurus, in Argolis on the Peloponnese peninsula, Greece. The museum, noted for its reconstructions of temples and its columns and inscriptions, was established in 1902 and opened in 1909 to display artifacts unearthed in the ancient site of Epidaurus in the surrounding area.

The Ancient Theatre of Epidaurus is a theatre in the Greek city of Epidaurus, located on the southeast end of the sanctuary dedicated to the ancient Greek God of medicine, Asclepius. It is built on the west side of Cynortion Mountain, near modern Lygourio, and belongs to the Epidaurus Municipality. It is considered to be the most perfect ancient Greek theatre with regard to acoustics and aesthetics. The monument retains the characteristic tripartite structure of a Hellenistic theatre that has a theatron, orchestra, and skene. During Roman times, the theatre (unlike many Greek theatres) did not suffer any modifications.

The Temple of Asclepius was a sanctuary in Epidaurus dedicated to Asclepius. It was the main holy site of Asclepius. The sanctuary at Epidaurus was the rival of such major cult sites as the Sanctuary of Zeus at Olympia and Apollo at Delphi. The temple was built in the early 4th century BC. If still in use by the 4th century AD, the temple would have been closed during the persecution of pagans in the late Roman Empire, when the Christian Emperors issued edicts prohibiting non-Christian worship.

Free time for lunch, coffee, or shopping at the ‘Naples of the East’ rich in Venetian architecture, cobbled squares, and towering castles with commanding views of the Argolic Gulf.
Afterwards, unwind by the harbor or get lost in the colorful back streets of the most elegant town in mainland Greece.
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 Nauplia, 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.

Enjoy the view of the water castle of Bourtzi, a Venetian castle located in the middle of the harbor of Nafplio, and take fascinating photos from the harbor side.

The Acronauplia is the oldest part of the city of Nafplion in Greece. Until the thirteenth century, it was a town on its own. The arrival of the Venetians and the Franks transformed it into part of the town's fortifications. Later, part of it was used as a prison until the Greek government decided that the view provided from its location would benefit the local tourism and built a hotel complex which still stands there today.

Palamidi is a fortress to the east of the Acronauplia in the town of Nafplio in the Peloponnese region of southern Greece. Nestled on the crest of a 216-metre high hill, the fortress was built by the Venetians during their second occupation of the area (1686–1715).
The fortress commands an impressive view over the Argolic Gulf, the city of Náfplio and the surrounding country. There are 913 steps in the winding stair from the town to the fortress. However, to reach the top of the fortress there are over one thousand, while locals in the town of Nafplion will say there are 999 steps to the top of the castle.
