Port Blair is the entry point to the Andaman Islands, and your time here will largely depend on your flight and ferry schedules. Private ferries to Havelock Island leave from Haddo Wharf between 6:00 AM and 2:00 PM, while government ferries depart from Phoenix Bay Jetty. It's crucial to check your ferry ticket for the correct departure point to avoid confusion. Booking private ferries in advance is recommended, especially during peak season from October to May.
