Introduction
The Andaman and Nicobar Islands sit far closer to Myanmar and Indonesia than to mainland India — a scattered archipelago of over 500 islands in the Bay of Bengal, of which only a small fraction are inhabited or open to visitors. What draws travellers here is a combination rare anywhere in India: turquoise water and coral reefs on a par with better-known Southeast Asian diving destinations, a colonial penal-colony history centred on Port Blair's Cellular Jail, and some of the last places on Earth where isolated indigenous communities continue to live entirely apart from the outside world, under strict legal protection.
Overview
Most Andaman itineraries centre on three islands. Port Blair, the capital, is the practical entry point and home to the Cellular Jail, the colonial-era prison where the British held political prisoners under the “Kala Pani” system — a sobering historical anchor before the trip turns toward beaches and reefs. Havelock Island (officially Swaraj Dweep) holds Radhanagar Beach, repeatedly ranked among Asia's best, and functions as the archipelago's main diving and beach base. Neil Island (Shaheed Dweep), smaller and quieter, offers a slower-paced alternative a short ferry ride away. Beyond these three, Ross Island's colonial ruins, now reclaimed by strangler figs and resident deer, make an easy day trip from Port Blair, while the wider archipelago holds significant marine biodiversity and, in its more remote reaches, indigenous communities whose islands and waters are legally protected from any visitor contact. Inter-island travel runs on ferries and a limited network of flights, and the islands' remoteness — a two-hour flight or several days by sea from the mainland — shapes a slower, less rushed kind of itinerary than most of India encourages.
Discover Andaman and Nicobar Islands
Port Blair, the archipelago's capital and main gateway, is built around a natural harbour and functions primarily as the practical base for arranging permits, ferries and onward travel. Its central historical site, the Cellular Jail, was built by the British colonial government in the early 20th century to hold political prisoners in solitary confinement — the “cellular” design, with cells arranged so no prisoner could see another, was intended specifically to isolate freedom-movement activists from mainland India. The site, now a national memorial, includes a sound-and-light show most evenings narrating this history, and stands as one of the more sobering colonial-era heritage sites in the country. The Samudrika Naval Marine Museum and Anthropological Museum in town add context on the islands' marine environment and indigenous cultures respectively, the latter presented through a conservation and protection lens rather than as a display of the communities themselves.
Ways to Experience This Destination
Port Blair's sobering national memorial to the British colonial penal-colony system, alongside Ross Island's fig-tree-reclaimed ruins of the former administrative headquarters.
Radhanagar Beach, ranked among Asia's finest, and a well-developed PADI diving scene on reefs that rival better-known Southeast Asian destinations.
A quieter alternative to Havelock with village guesthouses, good beaches and the tidal Natural Bridge rock formation.
Coral reef ecosystems beyond the main Havelock dive sites, from North Bay near Port Blair to more remote live-aboard destinations.
Andaman and Nicobar Islands — Practical Travel Notes
- Domestic travel permits apply to certain areas of the islands for Indian and foreign visitors alike — arranged routinely on arrival or in advance through a travel agent, standard administrative process rather than anything unusual.
- Indigenous community reserves, including the Jarawa and Sentinelese territories, are strictly off-limits by law. Do not stop, slow down or attempt any photograph or contact if travelling the Andaman Trunk Road near the Jarawa reserve — this is both illegal and a serious ethical line, not a grey area.
- The islands are reached by flight (roughly two hours from Chennai or Kolkata) or by a multi-day ferry from the mainland — most visitors fly given the time difference, reserving the ferry for a genuinely slow-travel preference.
- Inter-island travel runs on government and private ferries between Port Blair, Havelock and Neil Island, with schedules that can shift with weather — build a buffer day into any tight itinerary rather than scheduling a flight home the same day as the last island transfer.
- The dry season (roughly November to April) offers the best diving visibility and calmest seas; the monsoon (June to September) brings rain and rougher water that can disrupt ferry schedules and reduce visibility for diving.
- Coral reef health is a genuine concern here as elsewhere — choosing operators who brief divers and snorkellers on reef-safe practices (no coral contact, reef-safe sunscreen) supports the ecosystem's long-term health.
