Dublin - Satellite navigation systems have been causing chaos in Ireland's idyllic Ring of Kerry, a 180-kilometre stretch of road around the rugged landscape of the island's south-west, national broadcaster RTE reported Wednesday.

Large vehicles have travelled anti-clockwise around the circular route to and from Killarney since the 1800s, but modern sat-nav systems have been sending tourist coaches and lorries in the wrong direction.

The large vehicles are also getting trapped in tunnels and on bridges on the road which winds round the mountains of Macgillycuddy's Reeks on the Iveragh peninsula.

Councillors in Kerry have called for sat-nav systems to be updated, RTE reported. (dpa)
