The Barrow way is a 121km route following the Barrow river from the upper canal section at Robertstown in Co Kildare down to St Mullins village in Co Carlow. 

The Barrow is the second longest river in Ireland and was a major transportation route historically. A series of canals and locks were constructed to allow barges to navigate the river and a tow path to allow horses draw the barges now runs the length of the Barrow way, in paved and unspoiled, it's a predominantly grass verges, very flat and perfect for running and hiking.

This is a really cool route that covers all of the trails in Cromwell Valley Park, about 15 minutes outside of Baltimore, MD!

This was one of the last of the Victorian railways – it opened in 1899. It supplied milk to London and several quarries were opened along the track sending limestone to the industrial areas. The Trail was created after the railway closed in 1967. The signal box at Hartington Station has been preserved. You can go inside and see how it worked. At its southern end, the trail goes into a 600-metre long tunnel to emerge in the centre of Ashbourne.
