Being an Indian citizen, you do not need to apply for a passport to the Andamans because the Islands are a part of India.  One is required only to have a valid government ID (Aadhar or driver license). The foreigners on the contrary have to possess a passport, Indian visa, and Restricted Area Permit (RAP) in order to visit the islands.

Major islands are linked by ferries, which can vary with changes in weather, hence scheduled bookings are advisable.
