Starting at Kilbeggan, the trail follows the River Brosna for approximately 7 kilometres (4.3 miles) and the crosses countryside to the village of Ballinagore.[4] From Ballinagore, the route travels on to reach the shores of Lough Ennell at the townland of Lilliput, from which Jonathan Swiftused the name in Gulliver's Travels.[5] The trails follow tracks and roads around the lough, via Dysart village, before reaching Bellmount Bridge where it follows the Royal Canal to Mullingar with a rail-trail over the disused Mullingar-Athlone rail line to Athlone.[6][1][5]
A review of the National Waymarked Trails in 2010 found usage of the trail to be low and recommended that the amount of walking on tarred roads (41%) be reduced, that a series of looped walks off the main trail be developed and the trail should be promoted to day walkers.[3]
