Lonely Planet review
County Longford's main attraction is the magnificent Corlea Trackway , an Iron Age bog road that was built in 148 BC. An 18m stretch of the historic track has now been preserved in a humidified hall at the visitor centre, where you can join a 45-minute tour that details the bog’s unique flora and fauna, and fills you in on how the track was discovered, and methods used to preserve it. Wear a windproof jacket as the bog land can get blowy. The centre is 15km south of Longford on the Ballymahon road (R397).
