Sliabh an Iarainn Mountain is the wild and rugged mountain in County Leitrim. It rises 585 metres above sea level and is located on the eastern shore of Lough Allen. Sliabh an Iarainn or “Mountain of Iron” derives its name from the iron deposits to be found in the rocks. It is said that iron ore from the mountain was used in the construction of Dublin’s Halfpenny Bridge.
A visit to the Sliabh an Iarainn Visitor Centre in Drumshanbo tells more of the history of the region and there are three lovely looped walks perfect for exploring and enjoying this majestic landscape.
