Hi Rajeev, You can take a road trip from Kerala to Nepal in 2 weeks or maybe 20 days, if you want a more relaxed stay in Nepal. Assuming you are driving from Trivandrum, here is a rough plan for you: Trivandrum to Bangalore Bangalore to Chhindwara Chhindwara to Allahabad Allahabad to Gorakhpur and then to Kathmandu, Here is an article on the best places to see in Nepal and how to make the best of your stay there in Nepal, and your return can be done in the same way, with some changes in the halt stations, e.g you can return via Lucknow instead of Allahabad, and Ooty or Coorg instead of Bangalore. Have a happy trip!
