Don't trust outdated WikiTravel info http://wikitravel.org/en/Long_Island_(Andamans). This is where I had one of the most memorable experience including getting stuck in the middle of Andaman sea at night with a failed engine in the boat (thankfully my Note 3 worked and called the emergency by giving the GPS co-ordinates). Leela Kempinsky and other groups are investing in some of the islands and I wish I could have explored little bit more in some of these beautiful islands.
