The landscape of Kildare can be divided into three types. In the north, rich pastures provide the perfect environment for raising champion racehorses. To the west lie the plains of the Bog of Allen. In the south tillage farms dominate.
Kildare is quite a flat county. The highest point in the county is Cupidstown Hill (379m) which can be found in the west of the county.
The Liffey, the Barrow and the Boyne are three great rivers which flow through parts of Kildare.
Beneath the Curragh lies the mid-Kildare Aquifer. An aquifer is a layer of rock through which water can move easily. The aquifer holds vast quatities of crystal clear water which is rich in calcium. It provides a good supply of water to the Curragh Military Camp and the National Stud.
Another rare habitat is found just outside the Curragh, about 3km north-west of Newbridge. Pollardstown Fen is a protected area. A fen is a marshy, wet area of land. Pollardstown Fen is supplied with water from the Kildare Aquifer. All plants and animals on the fen are protected by law. Rare orchids and insect-eating plants can be found on some parts of the fen.
