Achaea in the context of "Agrampela, Achaea"

The Panachaiko (Greek: Παναχαϊκό, "Panachaean"), also known as Vodias (Βοδιάς) mainly at the Middle Ages, is a mountain range in Achaea, Peloponnese, Greece. It spans about 20 km in length from north to south, and 15–20 km from east to west. It is the northernmost mountain range in the Peloponnese. The highest point, named Pyrgos Palavou (Πύργος Παλαβού), is 1,926 metres (6,319 ft).

The mountain is home to two shelters, Greece's largest wind farm with 40 generators, which opened in 2006, and two communications stations. Snow is common in areas over 1,000 m in the winter. Paragliding is common in areas under 1,100 m. Due to overgrazing, frequent forest fires, and the appropriation of land for housing, the mountain's ecology and soil have suffered greatly, to the extent that much of the soil is now barren or can only support herbaceous vegetation. The range is sparsely forested, mainly on its western and southern slopes, while the most fertile areas lie on the eastern and western slopes.

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.

Elis (/ˈiːlɪs/) or Eleia (/ɪˈlaɪ.ə/; Attic Greek: Ἦλις, romanized: Ēlis [ɛ̂ːlis]; Elean: Ϝᾶλις [wâːlis]; Greek: Ήλιδα, romanized: Ilida) was an ancient district in the northwestern Peloponnese in Greece, roughly corresponding to modern regional unit of Elis. It was bounded to the northeast by Achaea, east by Arcadia, south by Messenia, and west by the Ionian Sea. The region is a fertile lowland with extensive plains, watered by the Peneus, Alpheus and other rivers that flow down from the Arcadian highlands. The region's name is probably cognate with the English 'valley'.

The Eleans traced their roots back to the mythical Dorian invasion. They united into a single polis ("city-state") centred on the city of Elis in 471 BC. Over the course of the archaic and classical periods, the city gradually gained control of much of the region of Elis, most probably through unequal treaties with other cities; many inhabitants of Elis were Perioeci—autonomous free non-citizens. Elis' main claim to fame was its control over the sanctuary at Olympia and the Olympic games.

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).

Rio (Greek: Ρίο, Río, formerly Ῥίον, Rhíon; Latin: Rhium) is a town in the suburbs of Patras and a former municipality in Achaea, Western Greece, Greece. Since the 2011 local government reform it is part of the municipality Patras, of which it is a municipal unit. The municipal unit has an area of 98.983 km. The municipal unit had a population of 14,219 in 2021. The campus of the University of Patras and the Casino Rio is located in Rio.

The Peloponnese Region (Greek: Περιφέρεια Πελοποννήσου, romanized: Periféria Peloponnísou, [periˈferia pelopoˈnisu]) is a region in southern Greece. It borders Western Greece to the north and Attica to the north-east. The region has an area of about 15,490 square kilometres (5,980 square miles). It covers most of the Peloponnese peninsula, except for the northwestern subregions of Achaea and Elis which belong to Western Greece and a small portion of the Argolid peninsula that is part of Attica.

The Pineiós (Greek: Πηνειός, Latin: Peneus) is a river in Peloponnese, Greece. It is probably not named after the god Peneus. It is 70 km (43 mi) long. Its source is on the southwestern slope of the mountain Erymanthus, near the village Kryovrysi. It empties into a bay of the Ionian Sea, southwest of Gastouni. For a part of its upper course, it forms the border between Elis and Achaea. The river flows through the plain of Elis. The river passes through the following villages:

• Kryovrysi
• Agia Triada
• Kalfas
• Kentro
• Kalyvia Ilidos
• Agia Mavra
• Kavasila
• Vartholomio

Akrotirio Araxou (Greek: Ακρωτήριο Αράξου) is a small coastal village of Achaea, Greece. The village lies at the northwestern part of Peloponnese near Cape Araxos. The village of Araxos and the namesake military airport are few kilometers away.

Since 2011, Akrotirio Araxou is part of the municipal unit of Larissos, of the municipality West Achaea. The village is beside a lagoon known as Pappas, Kalogria, or Araxos. The lagoon covers an area of 450 hectares and has a maximum depth of 3,4 m. In the 2011 population census it had a population of 35.
