County Carlow, one of Ireland’s smallest counties, is bordered by the scenic Blackstairs Mountains to the east. The fertile limestone land of the Barrow Valley and the Killeshin Hills lie in the west of Carlow.

The county’s most prominent feature is the 5000-year-old granite formation known as Browne’s Hill Dolmen. It's believed to have the largest capstone in Europe, weighing a colossal 100 tonnes.
