The Barrow Way – Graiguenamanagh to St. Mullins
The Barrow Way follows the towpath, originally a path alongside the River Barrow where horses pulled barges and goods for transport. Nowadays, visitors can enjoy excellent flat walking, passing good land where tillage and cattle farming is predominant. The path offers much of architectural interest to the visitor – bridges, many arched, and pretty lock houses, some still in use. The full length of the Barrow Way from Robertstown in Kildare to St. Mullins in Carlow is 113 kilometres. Accommodation is available at regular intervals and varies from hotels to self-catering and B&B.
The details in this post are mainly taken from the Guide to Carlow from carlowtourism.com and details the many walks and trails to discover around Carlow. The Barrow Way is divided into 6 stages and this post details the final stage, Stage 6, which is also the shortest.
