Hi, It is about 5800 kms from France (Calais) to Karachi.. This journey would take approximately 65 hours to drive. From U.K (dover or other port), you can take a ferry to France (Calais) It depends where in India you want you destination to be. From Karachi to India (generally), it would be 1000-3000 kms more.
