Booking a cruise from Chennai to the Andaman and Nicobar Islands is one of the more unusual travel experiences available from mainland India, and as of August 2026 it has become noticeably easier than it was even three years ago. The short version: you can book through the official shipping operator (the Shipping Corporation of India, which runs passenger vessels between Chennai/Visakhapatnam/Kolkata and Port Blair), through private cruise operators that have recently added Chennai departures, or through a travel agent or AI-powered booking platform that consolidates both. There is no direct online government booking portal comparable to IRCTC for trains, so most travellers either call the SCI Chennai office, use authorised agents, or rely on digital booking assistants to handle the paperwork, berth selection, and permit requirements.

The sea route from Chennai to Port Blair covers roughly 1,190 kilometres across the Bay of Bengal and typically takes 60 to 72 hours depending on the vessel and weather. This is not a luxury leisure cruise in the Western Caribbean sense; historically, these sailings have been functional passenger-cum-cargo ships serving island residents, though the experience has improved. Chennai's importance here is growing: The Hindu reported that Chennai is being positioned as a cruise hub with operators committing additional ships to the port, which means departure frequency from Chennai specifically should increase through 2026 and 2027 rather than remaining at the sparse historical schedule of roughly one sailing per week or less.
The voyage itself crosses open ocean with no intermediate stops, so you board in Chennai and disembark at Haddo Wharf in Port Blair. Sea conditions in the Bay of Bengal vary dramatically by season: October through March offers relatively calm water, while the southwest monsoon (June to September) can bring rough swells and occasional cancellations. If you are prone to seasickness, carry medication regardless of season, because even in fair weather the Bay of Bengal produces noticeable rolling motion on smaller vessels.
Your Three Booking Channels Compared
There are effectively three ways to secure a berth, and each has trade-offs worth understanding before you commit money.
| Feature | Shipping Corp of India (Direct) | Private Cruise Operators | Travel Agent / AI Booking Agent |
|---|---|---|---|
| Typical cost per person | ₹2,500–₹7,000 (berth class dependent) | ₹15,000–₹45,000 | Agent fee ₹500–₹2,000 plus ticket |
| Booking method | Phone/email to SCI Chennai office; limited counters | Operator websites and OTAs | Chat, app, or phone |
| Schedule reliability | Fixed but infrequent; subject to change | Seasonal itineraries | Depends on underlying operator |
| Cabin choice | Class-based (bunk, 1st class cabin) | Deck and cabin categories | Filtered search across options |
| Permits/RAP assistance | No | Sometimes bundled | Usually included |
| Best for | Budget travellers, locals | Holidaymakers wanting comfort | First-timers, time-poor travellers |
Step-by-Step: How to Actually Book
Start by fixing your dates around the sailing calendar. SCI publishes its monthly schedule through its Chennai port office and regional agents; private cruises publish seasonal calendars, often with departures concentrated November through March. Once dates are fixed, decide your cabin class early — on government vessels, first-class two-berth cabins sell out fastest, sometimes weeks ahead during peak season (December 20 to January 10, when LTC-driven domestic tourism spikes).
Next, prepare documentation. Indian citizens need a photo ID (Aadhaar, passport, or voter ID); foreign nationals need a Restricted Area Permit, which since 2018 has been granted on arrival at Port Blair for most nationalities, but you should verify current rules before sailing because ship-based entry procedures differ slightly from airport-based ones. Book your ticket by contacting the SCI agent network or your chosen operator directly, pay the advance (typically 25–50% for private cruises, full payment for government berths), and collect your e-ticket or boarding pass. Finally, plan the return: flights from Port Blair to Chennai take about 2 hours 15 minutes and start around ₹4,000–₹6,000 if booked 30–60 days out, versus ₹5,000–₹12,000 for last-minute fares.
A practical tip: build at least one buffer day into your itinerary. Ship schedules shift with weather and cargo loading, and a delayed arrival in Port Blair can cascade into missed inter-island ferries to Havelock (Swaraj Dweep) or Neil (Shaheed Dweep), which run on tight daily timetables.
Cost Breakdown: What You Will Actually Pay
Budget realistically for the full journey, not just the ticket. A government-ship passage in bunk class costs roughly ₹2,500–₹3,500 one way; a first-class cabin runs ₹5,000–₹7,000. Meals on SCI vessels are available but basic, budget another ₹1,000–₹1,500 for a three-day crossing. Private cruise fares range from about ₹15,000 for interior cabins on shorter itineraries to ₹45,000 or more for premium suites, usually including meals. Add port fees, GST (5% on most passenger fares), and travel insurance (₹300–₹800 for a domestic policy covering trip cancellation).
Compare this against flying: Chennai–Port Blair airfares average ₹5,000–₹9,000 round trip when booked 45 days ahead, so the cruise is rarely a money-saving choice — it is a choice about the journey itself. Where the economics do work is the one-way combination: sail to Andaman over three days, then fly back in an afternoon. That structure costs only marginally more than flying both ways while giving you the sea experience without sacrificing half your island holiday to the return crossing.
Common Mistakes Travellers Make
The most frequent error is assuming cruise availability mirrors flight frequency. Ships from Chennai may sail once weekly or less, and monsoon cancellations are real — June through September departures get rescheduled regularly. Booking a non-refundable hotel in Port Blair for a specific arrival date is therefore risky; choose flexible-rate accommodation or arrive with a day's slack.
Second, travellers underestimate seasickness. Even experienced flyers can struggle on a 65-hour crossing; buy motion-sickness tablets before boarding rather than relying on the ship's dispensary. Third, people confuse the Andaman tourist islands with the tribal reserve areas: North Sentinel Island and parts of the Nicobar group are strictly off-limits, and no legitimate operator will take you there — any tour promising such access is a scam or illegal. Fourth, some visitors skip checking baggage allowances; government ships have generous limits (often 50 kg or more), but private cruises follow airline-style rules. Fifth, waiting until December to book for the Christmas–New Year window almost guarantees disappointment; that fortnight sells out months in advance, particularly first-class cabins and any private-cruise suite category.
When to Book and When to Sail
Timing matters on two axes: when you sail and how far ahead you book. The sweet spot for sailing is mid-January through March and again October through early December — calm seas, good visibility for snorkelling, and fares below peak. Avoid late May through September unless you specifically want monsoon pricing and accept cancellation risk; iDiva's coverage of budget monsoon cruises notwithstanding, the Bay of Bengal in August is genuinely rough, and this article is being written on 21 August 2026, squarely inside that risky window.
For booking lead times: government berths open roughly 30 days before sailing and sell on a first-come basis, so set a reminder for the opening date. Private cruises release seasonal inventory earlier — book 60 to 90 days ahead for the best cabin selection and early-bird discounts, which commonly run 10–20% off brochure rates. If you are using an AI booking agent, its main value in this market is monitoring schedule changes and rebooking automatically when a sailing shifts, something manual bookers often discover too late.
Is the Cruise Worth It? A Critical View
Honesty requires acknowledging the downsides. The government vessel experience is spartan: shared facilities, limited dining hours, and three days at sea with no ports of call. If your goal is simply to reach the Andamans cheaply, a ₹4,000 flight beats a ₹3,000, 65-hour crossing on every metric except price alone. The private cruise product is better but still maturing; Chennai's new hub status means capacity is expanding, yet service quality varies between operators, and reviews are inconsistent.
Where the cruise genuinely earns its place is for travellers who value the passage itself — the novelty of approaching Port Blair by sea, the sense of following the old trade routes toward Java, Sumatra, and Malaya that made these islands a historic halt point — and for budget travellers with more time than money who want the cheapest possible way to reach the islands. It also suits LTC travellers: central government employees can now claim Leave Travel Concession against trips to these areas, and combining a subsidised outbound cruise with a discounted return flight stretches the benefit further. Choose deliberately, know what you are buying, and the crossing becomes a highlight rather than an ordeal.
Practical Checklist Before You Board
Confirm your sailing 48 hours before departure by phone — schedules do change. Pack motion-sickness medication, a power bank (cabin sockets are limited on older vessels), cash in small denominations (card acceptance aboard is unreliable), and photocopies of your ID. Arrive at the Chennai port terminal at least 3 hours before sailing; security and manifest checks are slower than airport equivalents. Keep your return flight or onward ferry bookings flexible, and download offline maps of Port Blair before losing signal at sea. Finally, register with your accommodation in Port Blair in advance — during peak weeks, walk-in availability near Aberdeen Bazaar is close to zero.
