Long Island (Andamans)
Long Island has very little infrastructure. There is one small village, and only 1 government resthouse that must be booked through Port Blair.
Flora and fauna
The permit you receive on arrival in Port Blair is good for Long Island.
There are two reasons to come to Long Island:
There is one government resthouse on Lalaji Bay which must be booked in Port Blair. Don't show up without a booking as you will likely be turned away, and other options don't really exist.
Other than a few tourists at Lalaji Bay the real reason to come here is for secluded self-sufficience... you must bring all of your own gear and food and cook for yourself. The government changes it's mind regularly about whether or not you can camp here... but it's possible to do it either way.
