Island hopping the Caribbean in one bag works when you pack to the strictest leg of the trip, not the most generous one: a soft bag of about 35 to 40 litres and under 10 kilograms, built for ferry decks, small turboprop cabins and immigration queues between different territories. Ferries such as FRS Express des Iles in the French Caribbean and Bahamas Ferries are comparatively forgiving with luggage. Short flights are not. Pack once to the flight limit, keep every document for every territory in one pouch, and the whole route, by sea or by air, becomes a single system.
Quick Facts
- Bag target: One soft sided bag, roughly 35 to 40 litres, plus a small personal item; aim for 7 to 10 kilograms total
- Ferry benchmark: FRS Express des Iles allows 1 checked bag up to 25 kilograms and 1 cabin bag up to 10 kilograms per passenger on its Guadeloupe, Dominica, Martinique and Saint Lucia routes, as published by the operator and checked on 10 November 2026
- Flight reality: Regional turboprop services set much lower and stricter cabin limits than ferries, and some small aircraft take no standard cabin bag in the cabin at all, so the flight leg sets your packing ceiling
- Ferry check in: The operator advises arriving at least 1 hour 30 minutes before departure for international routes between Guadeloupe, Dominica, Martinique and Saint Lucia
- Documents: Passport plus, for each territory, its own entry form, visa rules and onward ticket; rules change as you cross between French departments, independent states and other territories
- Core principle: Never plan a same day ferry to flight connection with no slack; weather, sea conditions and schedule changes are normal in the region
How do Caribbean ferry networks actually fit together?
There is no single Caribbean ferry system. There are clusters, each useful inside its own arc of islands, with flights filling the gaps between clusters. In the eastern Caribbean, FRS Express des Iles, the service long known as L’Express des Iles, links Pointe-a-Pitre in Guadeloupe with Roseau in Dominica, Fort-de-France in Martinique and Castries in Saint Lucia, running several round trips a week depending on the season. Crossings take roughly two and a half hours between Guadeloupe and Dominica and considerably longer for the full Guadeloupe to Martinique run via Dominica. Shorter local ferries connect Guadeloupe with Les Saintes and Marie-Galante in about an hour. Schedules are seasonal and changeable, so the operator’s live timetable, not a blog post or a printed guide, is the document to build around. Check it on the FRS Express des Iles Guadeloupe timetables and fares page before you book hotels on either side.
In the northwest, Bahamas Ferries connects Nassau with Family Islands including Eleuthera, Exuma, Andros, Abaco, Grand Bahama and Long Island, with services to Harbour Island and Spanish Wells. That network suits a Bahamas only hop, Nassau out to one or two Family Islands and back, rather than an international itinerary. Elsewhere, ferries are mostly local: between Antigua and Barbuda, between Saint Kitts and Nevis, between Saint Vincent and the Grenadines, and between the US and British Virgin Islands. The practical conclusion shapes your packing: most multi island trips mix at least one short flight with the ferries, and that flight is where a heavy bag becomes a fee, a gate check or a refusal.
Why does one bag change the trip so much?
Every hop involves the same sequence: check in early, pass immigration out and in, clear customs, and move your own luggage across a dock or up a gangway in the heat. With one soft bag you can carry everything up ferry stairs and walk straight off a small plane. With a large wheeled case, each step gets slower, and the case then has to fit into small taxis, guesthouse staircases and boat transfers.
One bag also protects the itinerary. Ferry operators adjust sailings for weather and operational reasons, and the operator’s own practical guide to Caribbean ferry travel stresses advance booking in peak periods such as Carnival and Easter. If a sailing moves, a single bag traveller can switch to a flight or a different port without repacking. Keep a first route simple: two or three islands in one cluster, three or more nights on each. If Trinidad at Carnival time is your anchor, our Trinidad Carnival first timer guide shows why that one event deserves its own unhurried block of days.
What is the one bag packing system?
Pack for heat, rain and air conditioning, in fabrics that wash in a sink and dry overnight. The wardrobe is five to six tops, two pairs of shorts, one pair of light long trousers, one set of smarter clothes for dinners and any entry requirements at upscale restaurants, swimwear times two so one set is always dry, underwear and sleepwear, and a light layer for ferries and flights, where air conditioning can be fierce even when the dock is at 30 degrees. Wear your heaviest items, usually trainers and the long trousers, on travel days. Everything else should roll into two packing cubes: one for clothes, one for swim and laundry, with a dry bag inside the main bag for wet swimwear and for boat days.
Footwear is where one bag trips fail, so cap it at two pairs worn or packed: walking trainers or sturdy sandals worn in transit, and one pair of reef safe sandals or water shoes packed flat. Add a wide brim hat that crushes and recovers, reef safe sunscreen bought before you reach small islands where choice is limited and prices are high, insect repellent, a small first aid kit, and any prescription medication in your personal item, never in a bag that might be gate checked or put in a ferry hold.
Technology stays minimal: a phone, charger, power bank and a dry pouch for ferry spray and sudden rain. Download tickets, bookings and entry form confirmations offline for every island, because connectivity at small ports is not guaranteed and immigration officers may ask to see onward travel details. The layering logic is the same one used in our Morocco winter packing carry-on system: few items, every item earning its place across several days and several settings.
How do documents work between territories?
Treat every hop as an international arrival, even when the distance is 30 miles. Guadeloupe and Martinique are French overseas departments and part of the European Union, but they are not in the Schengen area, and entry rules there are not identical to mainland France. Dominica, Saint Lucia, Antigua and Barbuda, the Bahamas and other independent states each set their own visa, passport validity and entry form rules, and several Caribbean destinations now use digital arrival forms completed before travel. British, Dutch and US territories in the region each apply their own rules again. Your nationality determines what applies to you, so check the official government or tourism authority page for every territory on your route, in order, before you book non refundable legs.
Keep one document pouch, physical and digital, for the whole trip: passport, printed or offline copies of every onward ticket, accommodation confirmations in arrival order, travel insurance documents, and any completed arrival form receipts. Carry proof of onward travel out of each territory, not just out of the region, because checks can happen at a ferry dock as readily as at an airport. Allow for fees too: some territories charge departure taxes or visitor levies, sometimes built into tickets and sometimes not, so a small reserve in US dollars and in local currency prevents a dockside problem.
How should you sequence ferries and flights?
Put the longest and least flexible leg in the middle of the trip, not at either end. Fly into the cluster’s best connected hub, ferry outward through the nearer islands, and fly home from the last island or ferry back to the hub with a spare night before your international flight. Never sleep on one island and rely on a morning ferry to catch an international flight from another island the same day. Sea conditions, mechanical issues and schedule changes are ordinary events, and a missed international connection costs far more than one extra hub night.
Build each travel day as a half day. With a 1 hour 30 minute ferry check in, a two to five hour crossing and immigration on arrival, a hop consumes most of a morning or afternoon. Plan a beach or a long lunch on arrival, not a timed tour. Finally, weigh your bag before the strictest flight. If it is over the cabin target, remove one item rather than hoping the desk will be lenient. On small turboprops, hope is not a baggage policy.
Frequently Asked Questions
Can you really island hop the Caribbean with only one bag?
Yes, and it is easier than with a large case. A 35 to 40 litre soft bag under 10 kilograms meets ferry cabin limits comfortably, stands the best chance on regional flights, and can be carried across docks, gangways and small island airports without help.
What is the ferry baggage allowance in the French Caribbean?
FRS Express des Iles publishes 1 checked bag up to 25 kilograms and 1 cabin bag up to 10 kilograms per passenger on its international routes, checked on 10 November 2026. Additional baggage is restricted, so confirm the current conditions on the operator site before you travel.
Do I need a passport to travel between Caribbean islands?
On international routes, yes. Each territory controls its own entry, including between nearby islands, and ferry check in includes immigration. Carry your passport, onward tickets and accommodation details for every stop, and complete any digital arrival form each territory requires.
How early should I arrive for a Caribbean ferry?
For international FRS Express des Iles routes, the operator advises at least 1 hour 30 minutes before departure. Arrive earlier in Carnival, Easter and school holiday peaks, and whenever you are travelling from a port you do not know.
Are Caribbean ferries reliable enough for tight connections?
No connection in the region should be planned as tight. Schedules vary by season and can change for weather or operational reasons. Keep a spare night before any international flight and treat every hop as a half day of travel.
What should never go in a checked or hold bag?
Passport and documents, medication, phone and power bank, payment cards and cash, and one change of clothes including swimwear. If a bag is delayed or gate checked, that personal item kit lets you start the island stay anyway.
Ferry baggage allowances, check in guidance and route information were checked against FRS Express des Iles operator pages on 10 November 2026. Entry rules are set by each territory and change; verify yours on official government sources before booking.
