Rising in the Devilsbit Mountains in the north of Tipperary, the River Suir runs down the length of the county before abruptly turning east in the face of the Knockmealdown Mountains. Along the way it nourishes countless dairy cattle and three significant towns along the southern border with Waterford. While Clonmel, the capital of South Tipp, holds little of interest for visitors, nearby Cahir is a compelling destination, with its mighty castle and the whimsical Swiss Cottage, and Carrick-on-Suir is the site of a rare and well-preserved Elizabethan manor house. Feeding into the Suir to the northwest of Cahir, the luscious Glen of Aherlow is one of the county’s prettiest spots and a fine base for exploring the scenic Galty Mountains. Tucked away on the south side of the range are the fantastic stalactites and stalagmites of Mitchelstown Cave, while the attractive villages of Clogheen and Ardfinnan lie to the east of here in the lee of the Knockmealdowns.
