Can I travel to any part of India on a tourist visa?
Yes, you can travel to every part of India on a tourist visa.
However, there are some places which are Restricted/Protected for visit by foreigners. These include some states in the North East of India which require Inner Line Permit for visit by foreigners. Such permits are issued by the concerned state governments. Some other areas which fall in the 'Restricted' category can be visited by tourists for which the Indian embassy can accord permission.
It is necessary for the applicant to clearly mention the places they are planning to visit during their stay in India including reasons for visiting such areas.
