Aetolia-Acarnania in the context of "Vonitsa"

Continental Greece (Greek: Στερεά Ελλάδα, romanized: Stereá Elláda; formerly Χέρσος Ἑλλάς, Chérsos Ellás), colloquially known as Roumeli (Ρούμελη), is a traditional geographic region of Greece. In English, the area is usually called Central Greece, but the equivalent Greek term (Κεντρική Ελλάδα, Kentrikí Elláda) is more rarely used.

It includes the southern part of the Greek mainland (sans the Peloponnese), as well as the offshore island of Euboea. Since 1987, its territory has been divided among the administrative regions of Central Greece and Attica, and the regional unit (former prefecture) of Aetolia-Acarnania in the administrative region of Western Greece.

The Gulf of Patras (Greek: Πατραϊκός Κόλπος, Patraikós Kólpos) is a branch of the Ionian Sea in Western Greece. On the east, it is closed by the Strait of Rion between capes Rio and Antirrio, near the Rio-Antirrio bridge, that is the entrance of the Gulf of Corinth. On the west, it is bounded by a line from Oxeia island to Cape Araxos. To the north it is bounded by the shore of Aetolia-Acarnania in continental Greece, and to the south by Achaea in the Peloponnese peninsula. It is 40–50 km (25–31 mi) long, 10–20 km (6–12 mi) wide, and has an area of 350–400 km.

The port city of Patras lies to the southeast and is the only major port on the gulf. It serves ferries to Ancona and Brindisi in Italy and to Cephalonia. On the northern shore Missolonghi, also has a port. The old ports of Rio and Antirrio lie at the east end of the Gulf; there is a ferry service between them which complements the traffic over the Rio-Antirio bridge. The gulf is rich in fish and molluscs, including sea snails and clams.

The Gulf of Corinth or the Corinthian Gulf (Greek: Κορινθιακός Κόλπος, romanized: Korinthiakós Kólpos, Greek pronunciation: [koɾinθiaˈkos ˈkolpos]) is an inlet of the Ionian Sea, separating the Peloponnese from western mainland Greece. It is bounded in the east by the Isthmus of Corinth which includes the shipping-designed Corinth Canal and in the west by the Rion Strait which widens into the shorter Gulf of Patras (part of the Ionian Sea) and whose narrowest point has been crossed since 2004 by the Rio–Antirrio bridge. The gulf is bordered by the large administrative divisions (regional units): Aetolia-Acarnania and Phocis in the north, Boeotia in the northeast, Attica in the east, Corinthia in the southeast and south and Achaea in the southwest. The tectonic movement across the gulf is comparable to parts of Iceland and Turkey, growing by 10 mm (0.39 in) per year.

In the Middle Ages, the gulf was known as the Gulf of Lepanto (the Italian form of Naupactus).

Antirrio (Greek: Αντίρριο, pronounced [aˈndirio], Latin: Antirrhium) is a town and a former municipality in Aetolia-Acarnania, West Greece, Greece. Since the 2011 local government reform it is part of the municipality Nafpaktia, of which it is a municipal unit. The municipal unit has an area of 50.794 km.

It is situated on the north side of the narrow (2.4 km) Strait of Rio, which separates the Gulf of Patras in the west from the Gulf of Corinth in the east. Since August 2004 the Rio–Antirrio bridge connects northwestern Greece with the Peloponnese. The name Antirrio means "opposite Rio".

Oxeia (Greek: Οξεία) is a Greek island in the Ionian Sea. As of 2011, it had no resident population. It is the chief island in the southern group (the Ouniades) of the Echinades, part of the Ionian Islands. Oxeia possesses the highest point in the Echinades, 421 metres (1,381 feet). It is situated near the mouth of the river Acheloos, off the coast of Aetolia-Acarnania. The island is around 5 kilometres (3 miles) in length and its width is approximately 2 km (1 mile). The Battle of Lepanto took place near the island in 1571.

In April 2012, it was bought by Qatar Holdings.

Cape Araxos (Greek: Ακρωτήριον Άραξος), also known as Cape Pappas (Άκρα Πάππα), is a cape in the northwest of the Peloponnese in Greece. It is the northwesternmost point of Peloponnese and separates the Gulf of Patras from the Ionian Sea. It lies at a distance of 30 km (19 mi) west of the city of Patras and very close to the village of Akrotirio Araxou. In 1877 a stone lighthouse was built, but it was destroyed during the Second World War and a modern lighthouse was installed after some years. The waters in the area are dangerous because of the continuous additions of sediments, eroding from the uplands of Aetolia-Acarnania via the rivers Acheloos and Evinos, The waters are quite shallow in some parts.

Missolonghi or Mesolongi (Greek: Μεσολόγγι, pronounced [mesoˈloɲɟi]) is a municipality of 32,048 people (according to the 2021 census) in western Greece. The town is the capital of Aetolia-Acarnania regional unit, and the seat of the municipality of Iera Polis Mesolongiou (Greek: Ιερά Πόλις Μεσολογγίου, lit. 'Sacred Town of Missolonghi'). Missolonghi is known as the site of a dramatic siege during the Greek War of Independence, and of the death of poet Lord Byron.

Ithaca (Greek: Ιθάκη) is one of the regional units of Greece. It is part of the region of the Ionian Islands. The capital of the regional unit is the town of Vathy. The regional unit consists of the islands of Ithaca, Atokos, Arkoudi, Oxeia, Drakonera and several smaller islands, all in the Ionian Sea. It has one municipality, Ithaca. The municipality includes islets other than Ithaca including two near Cape Melissa, Arkoudi and Atokos to the northeast and the numerous islets in the Echinades Island group (the larger ones being Drakonera, Makri, Oxeia, Petalas, and Vromonas) to the east near the mainland of Aetolia-Acarnania. Its largest towns are Vathy (pop. 1,676 in 2021), Perachori (368), Stavros (327), Platreithias (221), and Kioni (131).

In 2011, as part of the Kallikratis plan, the previous prefecture of Cephalonia was divided into the regional units of Cephalonia and Ithaca.
