Travelling by road to Chiang Mai from another country is challenging due to the distance and the need to navigate complex border crossings. It's generally not practical or recommended for travelers coming from India.
When planning a road trip from any of the above cities in India to Chiang Mai, there are considerable distances and international borders to be crossed. Therefore, for practical purposes, it is not recommended to undertake such a journey by road.
If one were to consider overland travel, multiple stopovers, visas, and special permissions for crossing borders would be required. The journey would traverse several countries, such as Myanmar, and could take weeks to complete. Since this is highly inadvisable, details of such a hypothetical route have not been provided.
