Arigna sits at the foot of the Arigna Mountains, where coal was worked from the 17th century until the last Irish mine closed in 1990. The Arigna Mining Experience lets you descend into the seams with men who spent their lives there—former miners guide you through the chambers and explain what the work took.
The Arigna River flows through the area, and the landscape curves toward Lough Allen and Iron Mountain (Sliabh an Iarainn). It's a small place, honest in its scarcity, but specific in what it holds: underground history, lived experience, the bones of industrial rural Ireland.

Wear waterproofs. Bring a sandwich. Tell someone where you're going if it's the mountain.
