Slieve Anierin, Mountain in County Leitrim, Ireland

Slieve Anierin is a mountain in County Leitrim, Ireland, rising to 585 meters (1,919 feet). It forms part of a range of hills that stretch across the county, with a broad, rounded summit and slopes covered in grass and heather.

The mountain has a long history of human activity, with evidence of ancient settlement and farming on its slopes. In the 19th century, iron mining took place on the mountain, leaving traces that can still be seen today.

The name Slieve Anierin comes from the Irish language, likely meaning 'mountain of the iron' or referring to an iron mine. Locals and visitors often climb it for the views and the sense of wildness, and it is a place for quiet walks and nature observation.

The mountain is best accessed from nearby roads, with parking available at trailheads. Weather can change quickly, so bring waterproof clothing and sturdy boots, and allow several hours for a round trip.

The mountain is home to a rare type of blanket bog, which supports plants like sundew and butterwort. These plants catch insects to survive in the nutrient-poor soil, a surprising sight for many visitors.
