Hello Maria,
Are you thinking of Mullagh in County Cavan? There is also a village of Mullagh in County Clare, plus some others around the island.
- First, Bus Eireann 109X from Dublin (Whitworth Rd Lower) to Kells (Parochial House)
- Second, Bus Eireann 108 from Kells (Parochial House) to Mullagh (Opp Sheridans).
I hope this is useful.
Wishing you a great trip,
David
