Self-drive cars are not generally available. An International Driving Permit is required. Taxis and auto rickshaws are available in large cities and fares should be charged by the kilometre. They do not always have meters but, where they do, visitors should insist on the meter being flagged in their presence. Fares change from time to time and therefore do not always conform to the reading on the meter, but drivers should always have a copy of the latest fare chart available for inspection.
Public transport is often crowded and can be uncomfortable.
Boat journey from Chennai takes 3-4 days.
