Land and Resources

The flat terrain is mainly covered by the Bog of Allen, Boora Bog, and Clara Bog. The River Shannon delineates Offaly's western border and the Grand Canal, which connects the Shannon and the Liffey, also flows through the county. The Slieve Bloom mountains rise to 518 m (1,700 ft) in the south-west.

Offaly has mild summers and winters. There is plentiful rain throughout the year, often accompanied by strong winds which blow unimpeded over the flat countryside.
