Kildare is an inland county of eastern Ireland in Leinster Province, bounded on the east by the counties of County Dublin and County Wicklow, on the south by County Carlow, on the west by County Laois and County Offaly, and north by County Meath. Its area is 654 square miles.
About 40,000 acres of the northwest section consists of the Bog of Allen. The rest of the surface is flat or slightly undulating.
The principal rivers are the Liffey, Boyne, Greese, Blackwater, and Barrow. Near Mullingar are three well known fishing lakes, Ennel, Owel, and Derrevaragh. The Royal Canal traverses the northern boundary line, connecting Dublin with the River Shannon at Cloondara. Many tourists are attracted to Kildare because of the great profusion of wildflowers.
The county town is Kildare. Other important towns in the county are Athey, Naas, Newbridge, and Maynooth.
