Ballycastle

united kingdom

Ballycastle perches on County Mayo's Atlantic cliffs overlooking Bunatrahir Bay, reached via the R314 from Killala or the N59 from Ballina 27 kilometres southeast. Most visitors drive from Belfast (282 km) or Dublin (265 km) as there's no rail service. The village serves as base for exploring the Céide Fields, the world's oldest field system at 5,000 years old, and nearby Downpatrick Head where the isolated sea stack Dun Briste stands 50 metres tall, completely severed from the mainland by Atlantic erosion.
