Cork is the
largest county in Ireland by land area, and the largest of Munster's six counties by population and area. At the latest census in 2022, the population of the entire county stood at 584,156. Cork is the second-
most populous county in the State, and the third-most populous county on the island of Ireland. County Cork is located in the
province of
Munster, bordering
Kerry to the west,
Limerick to the north,
Tipperary to the north-east and
Waterford to the east. The county shares separate mountainous borders with Tipperary and Kerry. The terrain on the Kerry border was formed between 360 and 374 million years ago, as part of the rising of the
MacGillycuddy's Reeks and
Caha Mountains mountains ranges. This occurred during the
Devonian period when Ireland was part of a larger continental landmass and located south of the
equator. The region's topography of peaks and valleys are characterised by steep ridges formed during the
Hercynian period of
folding and
mountain formation some 300 million years ago. Twenty-four historic
baronies are in the county—the most of any county in
Ireland. While baronies continue to be officially defined units, they are no longer used for many administrative purposes. Their official status is illustrated by Placenames Orders made since 2003, where official Irish names of baronies are listed. The county has 253 civil parishes. Townlands are the smallest officially defined geographical divisions in Ireland, with about 5447 townlands in the county.
Mountains and upland habitats The county's mountains rose during a period
mountain formation some 374 to 360 million years ago and include the
Slieve Miskish and
Caha Mountains on the
Beara Peninsula, the
Ballyhoura Mountains on the border with Limerick and the
Shehy Mountains which contain
Knockboy (706 m), the highest point in Cork. The
Shehy Mountains are on the border with Kerry and may be accessed from the area known as Priests Leap, near the village of Coomhola. The upland areas of the
Ballyhoura,
Boggeragh,
Derrynasaggart, and
Mullaghareirk Mountain ranges add to the range of habitats found in the county. Important habitats in the uplands include blanket bog, heath, glacial lakes, and upland grasslands. Cork has the
13th-highest county peak in Ireland.
Rivers and lakes Three rivers, the
Bandon,
Blackwater and
Lee and their valleys dominate central Cork. Habitats of the valleys and floodplains include woodlands, marshes, fens, and species-rich limestone grasslands. The River Bandon flows through several towns, including
Dunmanway to the west of the town of
Bandon before draining into Kinsale Harbour on the south coast. Cork's sea loughs include
Lough Hyne and
Lough Mahon, and the county also has many small lakes. An area has formed where the River Lee breaks into a network of channels weaving through a series of wooded islands, forming 85 hectares of swampland around Cork's wooded area. The Environmental Protection Agency carried out a survey of surface waters in County Cork between 1995 and 1997, which identified 125 rivers and 32 lakes covered by the regulations.
Land and forestry Like many parts of Munster, Cork has fertile agricultural land and many bog and peatlands. Cork has around 74,000 hectares of peatlands, which amount to 9.8% of the county's total land area. Cork has the highest share of the national forest area, with around of forest and woodland area, constituting 11.6% of the national total and approximately 12% of Cork's land area. It is home to one of the last remaining pieces of native woodland in Ireland and Europe. is the most south-westerly point of both Cork and Ireland
Wildlife The
hooded crow,
Corvus cornix is a common bird, particularly in areas nearer the coast. Due to this bird's ability to (rarely) prey upon small lambs, the gun clubs of County Cork have killed many of these birds in modern times. A collection of the marine
algae was housed in the
herbarium of the
botany department of the University College Cork. Parts of the South West coastline are hotspots for sightings of rare birds, with
Cape Clear being a prime location for bird watching. The island is also home to one of only a few gannet colonies around Ireland and the UK. The coastline of Cork is sometimes associated with whale watching, with some sightings of fin whales, basking sharks, pilot whales, minke whales, and other species.
Coastline Cork has a mountainous and flat landscape with many beaches and sea cliffs along its coast. The southwest of Ireland is known for its peninsulas and some in Cork include the
Beara Peninsula,
Sheep's Head,
Mizen Head, and
Brow Head. Brow Head is the most southerly point of mainland
Ireland. There are many islands off the coast of the county, in particular, off
West Cork.
Carbery's Hundred Isles are the islands around Long Island Bay and Roaringwater Bay.
Fastnet Rock lies in the
Atlantic Ocean 11.3 km south of mainland Ireland, making it the most southerly point of
Ireland. Many notable islands lie off Cork, including
Bere,
Great Island,
Sherkin, and
Cape Clear. With an estimated of coastline, Cork is one of three counties which claims to have the
longest coastline in Ireland, alongside
Mayo and
Donegal. Cork is also one of just three counties to border two bodies of water – the
Celtic Sea to the south and the
Atlantic Ocean to the west. Cork marks the end of the
Wild Atlantic Way, the tourism trail from
County Donegal's
Inishowen Peninsula to
