Andaman and Nicobar
Andaman and Nicobar  are a large group of nearly 600 islands in the Bay of Bengal. Though they are a part of India politically, they are closer to Myanmar and Thailand than to the Indian mainland. They are grouped here with Southern India. They were just north of the epicenter of the Boxing Day quake of 2004, and were the site of dozens of aftershocks. The Nicobars were badly hit by the resulting tsunami, while the Andamans escaped with a few bruises. With the exception of Little Andaman Island and the Mahatma Gandhi Marine National Park, the rest of the tourist destinations are operating normally again.
1400 km from mainland India and 1000 km from Thailand, the Andaman and Nicobar Islands are one of the most remote spots on the planet. The original inhabitants are various aboriginal tribes who exist more-or-less out of the mainstream. There are some tribes who have had no contact whatsoever with the rest of the world. Of nearly 600 islands, only 9 are open to foreign tourists, and all of these are in the Andamans.
The islands exist in India's popular consciousness mainly because they were used as a penal colony by the British rulers to imprison rebels and freedom fighters, in addition to hardened criminals. Most of the inhabitants of these islands are in fact migrants from the mainland, some of them descended from the prisoners.
During World War II, the Andamans were the only part of India briefly occupied by the Japanese. While notionally handed over to Subhash Chandra Bose's Free India, in practice the Japanese held the reins of power. The territory was run brutally — suspected resistance members were tortured and executed, and when food started to run out towards the end of the war, people were deported to uninhabited islands to fend for themselves as best they could.
Mid-January until mid-May sees the best weather, and often the best diving conditions. The days are mostly sunny at this time of year, and the sea sometimes flat enough to reflect the clouds. The monsoon usually hits around late May, lasting until the end of July, and is probably the worst time to visit the islands – strong winds, frequent rain and low visibility underwater. August through November some occasional showers and slightly rougher seas are possible but diving can still be great at this time of year. The weather often takes a turn for the worse for the month of December through early January. Andaman has a moderate temperature all through the year within the range of 23 degrees to 31 degree celsius. It has tropical climate, there are no severe climate conditions except for tropical storms and rains in late Summer and Monsoon.
The Andaman and Nicobar Islands stretch out almost 500 km in length, with the Andamans in the north and the Nicobars in the south. The main island, aptly known as Great Andaman, is divided into 3 portions - North Andaman, Middle Andaman and South Andaman. Port Blair is located on South Andaman.
Non-Indians need a Restricted Area Permit to visit the islands, but these are now issued on arrival at the Port Blair airport. If you plan to arrive by sea, you'll need to arrange your permit before arrival, either in Chennai or when applying for your Indian visa. Visitors usually receive a 30 day permit, although some travellers arriving without a confirmed flight back have only received a 15 day permit. Ask for the full 30 days in your application; if you write in your return flight date, your permit will be issued to end on that date, which will cause unnecessary pain if you choose to extend your stay or, worse yet, get unexpectedly delayed by weather.
Permits can be extended by 15 days in Port Blair, for a maximum single stay of 45 days, although this extension is granted only in, to quote the local police guidelines, "deserving cases". You must then leave the islands and can return after 72 hours. The permit is checked when arriving at most islands, checking into hotels and booking ferries, and must be surrendered when you leave the islands, so don't lose it.
The permit allows overnight stays in the following locations: South Andaman Island, Middle Andaman Island and Little Andaman Island (except tribal reserves), Neil Island, Havelock Island, Long Island, Diglipur, Baratang, North Passage and islands in the Mahatma Gandhi Marine National Park (excluding Boat Hobday Island, Twin Island, Tarmugli Island, Malay Island and Pluto Island). Overnight stays in the park are with permission only.
The permit allows for day-trips to: South Cinque Island, Ross Island, Narcondum Island, Interview Island, Brother Island, Sister Island and Barren Island which can be visited on board vessels only with landing possible.
Indian nationals do not require a permit to visit the Andamans. However, permits are required to visit Nicobar Islands and other tribal areas, which are rarely given. Application on a prescribed form may be addressed to the Deputy Commissioner, Andaman District, Port Blair.
Andaman’s airport is at Port Blair. it's connected to Chennai, Kolkata and lots of different cities within the country. Jet and Air India are the most important flights operators for Andaman. throughout the tourer seasons discounted airfares also are provided by the airlines. the price of the tickets is usually cheap, particularly if reserved earlier.
For now the only way to reach the Andamans by air is from the Indian mainland to Port Blair. There are talks of opening up flights from Bangkok, which could drastically change the situation in the islands, but as of 2009 these remain just plans. Flights can fill up in peak season and immigration doesn't look kindly on people arriving without confirmed flights back, so book a return ticket and change the flight date if you decide to hang around longer.
Flights to Port Blair are not really "low-cost", if compared to the same airlines' mainland India flights, but still cheaper than any other way to get to islands. Price varies significantly with date, so if your travel dates aren't fixed, you can save significantly by choosing the right day to fly. Advance booking (available on respective airline's website) at least several days before trip is recommended.
Port Blair's Vir Savarkar Airport is probably one of the most quaint and idyllic airports in India. There is a scenic view point where the whole airport can be seen. There are no night flights as the airport is handed over to the Indian Air Force after 3pm.
It is possible to take a ship from Kolkata (~60 hrs), Chennai or Visakhapatnam which takes almost 4 days to arrive in Port Blair. It is less expensive. Facilities are basic, though and many prefer to sleep on the deck rather than in the cramped bunks. The ferries can take up to five days to arrive depending on weather and various other variables... this can be quite frustrating for many.

Andaman and Nicobar are a vast archipelago, and aside from some erratic, infrequent and expensive helicopter shuttles and a pricy seaplane service to Havelock Island, passenger ferries are the only way to get between the islands. There is also the Infiniti Liveaboard that makes trips to destinations such as Cinque, Barren, Narcondam and other islands.
All passenger transport in the islands is handled by the government-run Directorate of Shipping Services (DSS), which also runs the ferries back to the mainland. The DSS operates basically two kinds of vessels: small "tourist" ferries, and larger "local" ferries. Despite the names, fares are more or less identical on both, at Rs.150-200 one way from Port Blair to Havelock Island.
Tourist ferries seat about 100 people in padded bucket seats in a notionally air-conditioned cabin (which can still get sweltering hot). While you can access the top deck, there are no seats, shade or shelter outside. These boats are fast(er) and seaworthy, but top-heavy, and sway quite a bit in high seas. There is no canteen on board, so bring snacks or at least drinks.
Local ferries are considerably larger, seating up to 400 in two levels: padded "bunk" or "luxury" seating upstairs, and plain old benches on the "deck" downstairs. Neither class is air-conditioned, but ocean breezes keep temperatures tolerable, and a canteen dishes out chai(tea), samosas and bottled water. Due to their larger size, they're more stable in heavy seas, but take about twice as long as tourist ferries to get anywhere.
There's a new a/c catamaran ferry from Port Blair to Havelock. Tickets are 650, 750 or 1000 (which gets you a leather seat and your own tv) and can be booked from a dedicated ticket booking window at Port Blair, thus avoiding the queue barging, and through your guesthouse (or wild orchid, emerald gecko & andaman bubbles) on Havelock.
In high season demand often exceeds supply, so book your tickets at least one day in advance, either through a travel agent or directly at Port Blair's harbour. Ferry ticket booking has now been computerised. This means you can book any ferry from any jetty - i.e. Rangat to Havelock from the Diglipur ferry jetty. This obviously depends on the computers working! Services may be changed or cancelled at short notice due to inclement weather, notably cyclones in the Bay of Bengal. If you're prone to sea-sickness, pop a pill an hour before you get on board.
The only place with historical attractions of note is Port Blair, which houses both British-era colonial buildings, including the notorious Cellular Jail, and a few World War II bunkers dating from the brief Japanese occupation.
Neil Island: It is an amazing beautiful island with lush green forests and sandy beaches. This island is located at a distance of around 36 kms from the Port Blair. This is a perfect outing and holiday destination for the Eco-tourists.
Some people come to see members of the Jarawa Tribe. However, this is not recommended as contact with the outside world can be dangerous to the Jarawas' health. Groups such as Survival International encourage people to stay away from the reserve that they inhabit.
The best dive sites in the Andamans are in very remote locations and accessible via a liveaboard. The dive sites around Havelock are actually very ordinary by Andamans standards. The best diving in the Andamans is: Barren Island (an active volcano), Narcondam Island (an extinct volcano), Invisible Bank (an extensive seamount approx. 100 miles Southeast of Port Blair) and 4 spectacular but un-named sea mounts off the west coast. There is also a good wreck dive just south of North Brother Island. There is one regular liveaboard in the Andaman Islands - the Infiniti Liveaboard, and it is the best way to get around. Its brand new & fully equipped, though a little expensive but well worth the money for the comfort & adventure.
Seafood is the order of the day. From upscale restaurants in Port Blair to local dhabas on Havelock, fish abounds. Be prepared to pay a little more for good fish and seafood dishes than for standard indian food, but it's well worth it. Basic Indian food is also available, and as cheap as on the mainland in most of the small dhabas. Resort restaurants on Havelock can also whip up a limited set of more or less Western dishes, but the resort restaurants are pretty expensive for Indian standards. Fresh Crab & Tuna can be enjoyed here.
Booking A&N Tourism Accommodation
There are a variety of hotels around the islands which are run by Andaman & Nicobar Tourism. You can book all A&N tourism hotels both in person at A&N tourism in Port Blair, by phone on 03192 232694, or by email on email@example.com. Tariff is Rs. 1000 per night for a double occupancy room. But these rooms get booked from months in advance. Hours are 0830-1100,1400-1500.
The Andamans are a fairly safe destination. Tourism is still in its early stages which makes it almost hassle free. That said, you should keep your wits about you as you would anywhere.
The Andaman Islands are the home of some of the last un-contacted tribes of Eurasia. These tribes have resisted modernization for some time. An example is the Sentinelese tribe, who inhabit North Sentinel Island. They maintain their sovereignty over the island and are hostile towards outsiders. However, as a tourist, you will go nowhere near them, so this is not really an issue. Actually, the Indian government bans entry into the island.
Saltwater crocodiles (Crocodylus porosus) are present within suitable habitat throughout the Andaman & Nicobar Islands.
While attacks on locals do occur every year within the island chain, the only attack on a foreigner within recent history occurred off the coast of Havelock Island in April of 2010. While saltwater crocodiles generally remain within the rivers and coastal mangrove swamps, they do occasionally travel within the open ocean, as was the case in this attack. Attacks on humans in the ocean are very rare.
The main crocodile populations are around Little Andaman Island (Northern and Western sides), Interview Island and in the narrow straits that seperate the main islands MacPhearson Strait, Andaman Strait, Homfrey Strait and Austen Strait. Crocodile populations are also known from many of the Nicobar Islands.
Andaman and Nicobar are malarial, although generally no more so than mainland India.
The Indian country code applies here (91) and the area code for the entire Andamans is (3192). So, from outside India, you dial +913192xxxxxx. Within India, you dial 03192xxxxxx.
Mobile phone coverage nominally exists on many islands, but the coverage is poor and dropped signals are the norm. State owned BSNL, and private operators Airtel and Vodafone-Essar are the operators providing mobile services there. Landlines are frequent in Port Blair, but more erratic as you move around the islands.
Internet access is slow but tolerable in Port Blair,BSNL EVDO Sticks on CDMA Technology Works the best with Speed upto 1 Mbps,Bsnl 3g Gives speed around 100 kbps and ADSL is un-serviceable most of the times. Private Players like Airtel,Vodafone offers Internet Acess Through GPRS & EDGE which is pathetically Slow. Reliance Internet Only works in the City but slow. Project for Inter Connectivity of Islands with Underwater international Chennai-Singapore marine cable is under Consideration.Once finished will offer Seamless and fast connectivity .
Tourism is still relatively new on the Andamans and as such the traveler has a special responsibility in guiding its developement. Leave the bikinis on the beach. Remember that this is India and local women are very conservative in their attire. Alcohol should be consumed on the premises of your hotel only. The quiet and peacefulness of the islands are one of their best assets; help to maintain these.
