Cnoc Uí Choileáin
The place name
The Irish name Cnoc Uí Choileáin means "hill of the O'Coileáin" — a local sept that held the rise for generations. The O'Coileáin were minor gentry in west Limerick, never grand enough for the histories. The name survives. The septs are gone. The hill is still here.

The greenway
The Limerick to Tralee railway line ran through west Limerick and closed in 1976. The track bed became the Great Southern Greenway, opening in 2021 as a walking and cycling trail. Mountcollins is close enough to tap into it — ten minutes west toward Abbeyfeale or east toward Newcastle West. The viaducts and the old station sites are still there, ghosted into the landscape.
