Travelling by road in Idukki
Idukki has no railway line, so roads carry almost all travel in and out of the district. Most journeys involve ghat sections with steep climbs and tight bends, so travel times are usually longer than the distance suggests.
Hill roads can be affected by heavy rain and landslides during the monsoon. Before a long journey, check current conditions with local authorities. Route details here are summaries and are marked as verified only once they have been checked.
