The Barrow is the making of this county: a great river running through farmland and small towns in the south-east midlands. It is a compact, largely rural county of farmland, river walks and small towns, with the Blackstairs Mountains forming its eastern border with Wexford and offering its best hill walking.
Carlow town has a long history as a Norman stronghold, and the county is rich in early monuments, from the great Brownshill Dolmen to medieval churches. Gardens are a particular strength, and the Barrow Way towpath gives walkers and cyclists a gentle, scenic route through the county. It is also a good-value, unhurried base for the wider southeast: Kilkenny, the Wicklow Mountains and Waterford are all within reach, while Carlow itself stays refreshingly local, with weekly markets, riverside pubs and a strong sense of a working county town.
