Andaman Islands Travel Guide: Radhanagar Beach, Scuba Diving, and Itinerary

Floating in isolation in the Bay of Bengal over 1,200 kilometers east of mainland India, the Andaman and Nicobar archipelago is a tropical paradise of dense primeval rainforests, blindingly white powdery coral beaches, and world-class underwater coral reefs teeming with manta rays, sea turtles, and kaleidoscopic reef fish. Once feared as Kalapani (the Black Waters) during British colonial imprisonment, the islands today represent India’s premier luxury beach and scuba diving frontier.

However, because the islands are separated by open ocean waters and governed by strict ecological and indigenous tribal protection mandates, island-hopping requires meticulous advance planning. A missed ferry booking can leave you stranded in Port Blair; an uncertified dive shop can compromise underwater safety. Based on extensive field investigations across the islands, we present this complete 7-day masterplan covering ferry booking, dive site selection, and coastal itineraries.

7-Day Island-Hopping Master Itinerary

Days 1 & 2: Port Blair (Colonial History & Marine Sanctuaries)

• Fly into Veer Savarkar International Airport (IXZ) in Port Blair.
• Cellular Jail National Memorial: Tour the imposing three-story panopticon penitentiary built by the British between 1896 and 1906 to exile Indian freedom fighters (including Veer Savarkar and Batukeshwar Dutt). Attend the poignant evening Sound & Light show narrating the struggle for independence.
• Ross Island (Netaji Subhash Chandra Bose Dweep): Take a 15-minute speed boat to explore the haunting, jungle-draped ruins of the former British colonial administrative headquarters, where banyan tree roots have swallowed colonial ballrooms, churches, and hospitals, now inhabited by wild spotted deer and peacocks.

Days 3 to 5: Havelock Island (Swaraj Dweep) – The Tropical Epicenter

Board a morning private luxury catamaran ferry (Makruzz, Green Ocean, or Nautika) from Haddo Wharf in Port Blair to Havelock Island (90-minute smooth voyage across the open sea).

• Radhanagar Beach (Beach No. 7): Step onto two kilometers of curving white silica sand framed by towering tropical mahua rainforest trees. The turquoise water here is crystal clear, completely devoid of rocks or coral underfoot, making it the safest and most idyllic ocean swimming beach in Asia. Savor the radiant sunset as the sky turns vivid violet and gold.
• Elephant Beach & Coral Reefs: Accessible by a 30-minute forest hiking trail or a short boat ride from the jetty. Elephant Beach is the hub for beginner-friendly sea walks, parasailing, and snorkel excursions over shallow branching staghorn coral beds.
• Kalapathar Beach: A wilder shoreline littered with dark volcanic boulders contrasting dramatically against turquoise water and white sand. Perfect for solitary sunrise walks.

Days 6 & 7: Neil Island (Shaheed Dweep) & Return to Port Blair

Take a 45-minute ferry from Havelock south to tiny, laid-back Neil Island:

• Natural Bridge (Howrah Bridge): A stunning geological rock formation carved over millennia by tidal action into a massive living coral arch. Explore the exposed coral reef pools at low tide to spot live sea cucumbers, starfish, and clownfish.
• Bharatpur & Laxmanpur Beaches: Bharatpur offers calm, shallow waters ideal for glass-bottom boat rides, while Laxmanpur Beach is celebrated for its shell-strewn shoreline and golden sunset point.
• Return by afternoon catamaran to Port Blair for your flight back to mainland India.

Mastering the Inter-Island Ferries

Movement between Port Blair, Havelock, and Neil is dependent on maritime ferries:

• Private Catamarans (Recommended): Operators like Makruzz, Nautika, and Green Ocean provide fully air-conditioned catamarans with reserved plush seating, onboard cafeterias, and luggage handling. Tickets cost between ₹1,200 and ₹2,500 per passenger each way. Book online 4 to 6 weeks in advance via their official portals.
• Government Directorate of Shipping Services (DSS) Ferries: Slower, conventional passenger ships primarily serving local islanders. While substantially cheaper (₹400 – ₹700), tickets are difficult to secure online and prioritize local residents.

Night Kayaking & Bioluminescence in Havelock

One of the most astonishing nocturnal experiences in the Andamans is guided night kayaking through the mangrove creeks of Havelock Island. On moonless nights, the water comes alive with bioluminescent phytoplankton (dinoflagellates). With every stroke of your paddle, the water glows with electric blue and green fairy-dust sparks—a phenomenon that feels like gliding across a starry galaxy.

Baratang Island: Mangrove Boat Safaris & Limestone Caves

Located 100 kilometers north of Port Blair, Baratang Island provides an adventurous day excursion. Board a speedboat through dense tropical mangrove tunnels where foliage forms a natural vaulted roof overhead. A 1.2-kilometer trek through rural teak forests leads to colossal subterranean limestone caves featuring ancient stalactite and stalagmite rock formations sculpted over millions of years.

Packing Essentials for the Andamans

• Reef-Safe Sunscreen: Traditional sunscreens containing oxybenzone and octinoxate bleach and kill coral reefs. Use mineral-based, reef-safe zinc sunscreens.
• Waterproof Dry Bags: A 10L to 20L roll-top dry bag is essential for protecting smartphones, cameras, and wallets during boat transfers and beach landings.
• Snorkel & Mask: While rental gear is plentiful, bringing your own properly fitted silicone mask ensures leak-free snorkeling at remote beaches.
• Cash Reserve: ATMs on Havelock and Neil frequently experience satellite network drops or run out of cash. Carry at least ₹10,000 to ₹15,000 in physical cash from Port Blair.
