The Caribbean is an archipelago of islands scattered across the sea, and while the image of island-hopping by boat is a romantic one, the practical reality is more selective. Ferries operate reliably between some groups of islands — particularly in the Eastern Caribbean — but between others the distances are simply too great or the services too infrequent, and flying is the only realistic option. Here is how to navigate the Caribbean by sea, and where to accept that a flight is the answer.
Where ferries work: the Eastern Caribbean
The most developed ferry network in the Caribbean runs through the Lesser Antilles — the chain of smaller islands stretching from the Virgin Islands south to Trinidad. Several operators run scheduled services here:
L'Express des Iles
L'Express des Iles is the principal inter-island ferry operator in the French Caribbean, running high-speed catamaran services between Guadeloupe, Martinique, Dominica and St Lucia. Journey times are meaningful — Guadeloupe to Martinique takes around 3.5–4 hours — but the service is reliable, runs several times a week, and is particularly popular with travellers moving between the French Antilles without flying. The vessels are modern catamarans, and fares are reasonable. Book in advance during high season (December to April) when both tourists and locals compete for seats.
Windward Islands Ferries (formerly JOIA)
Windward Islands Ferries covers the southern chain, including routes between St Vincent, the Grenadines, Grenada, Carriacou and Petite Martinique. The Grenadines in particular are ferry territory — the small islands of Bequia, Mustique, Canouan, Mayreau and Union Island are all linked by regular services, and this is one of the few places in the Caribbean where boat transport is genuinely the most natural way to island-hop. The Osprey ferry also covers some of these routes, particularly between St Vincent and Grenada.
For travellers based in St Vincent and the Grenadines, a combination of scheduled ferries and the occasional water taxi connects most of the chain in a day or two.
Ferries in the US and British Virgin Islands
The Virgin Islands are well served by ferries. Between St Thomas and St John (USVI), frequent passenger ferries run throughout the day and take just 20 minutes — this is essentially a water bus rather than an adventure. Road Town (Tortola, BVI) and Virgin Gorda are connected to the USVI by Speedy's, Native Son and other operators, making the BVI accessible without flying for visitors based in St Thomas or St John. Note that crossing between USVI and BVI involves an international border and passport requirements even by ferry.
Trinidad, Tobago and Barbados
Trinidad to Tobago is one of the Caribbean's most-used ferry routes. The Water Taxi Authority (formerly PTSC) and the inter-island Express vessels serve this route, with crossing times of around 2.5–3 hours. Day-trip and same-day return journeys between the islands are popular among Trinidadian residents. The fast ferry can be rough in choppy conditions — the distance is about 100 km.
Barbados is notably isolated — the island sits east of the Lesser Antilles chain and has no regular ferry connections to its neighbours. Getting to Barbados means flying in.
Where you must fly: the larger gaps
The Caribbean's geography works against ferries between many islands. Some key gaps to understand:
- Cuba, Jamaica, the Cayman Islands, Hispaniola (Haiti and Dominican Republic) and Puerto Rico — these larger islands have no regular passenger ferry connections to each other or to most of the rest of the Caribbean. Inter-island travel here means flying.
- The Bahamas — the chain extends over enormous distances from Florida to the Turks and Caicos, and while some inter-Bahamian ferries exist between closer cays, most travel requires small aircraft. The ferry from Miami to the Bahamas (Balearia Caribbean) does run, but it is a long overnight crossing.
- Anguilla and St Martin / Sint Maarten — a short ferry hop from Marigot or Philipsburg to Blowing Point is one of the Caribbean's most convenient crossings, taking about 20 minutes. Worth knowing for travellers in that corner of the northern Leewards.
- Turks and Caicos to Dominican Republic — no regular ferry; you fly.
Booking Caribbean ferries
Most Caribbean ferry operators still sell tickets at the port on the day, but high-season bookings — particularly L'Express des Iles and popular Trinidad–Tobago sailings — benefit from advance booking. The operators' own websites handle this for most routes, though some require booking through local agents. A journey-comparison site is useful for confirming which routes exist; for actual tickets, go directly to the operator.

Practical tips for Caribbean ferry travel
Sea conditions in the Caribbean vary considerably. The Caribbean Sea on the western side of the island chain is generally calmer; the Atlantic side (particularly around the open-water passages between islands) can be rough, especially between January and March. High-speed catamarans are more prone to motion in choppy conditions than slower conventional ferries. If you are susceptible to seasickness, take precautions — over-the-counter remedies work but are better taken before boarding than after you feel ill.
Most ferry terminals are straightforward, but bring your passport — even between islands of the same nation-state, some crossings between different countries' territorial waters require documentation. The USVI–BVI crossing is an international border regardless of how short it feels.
Frequently asked questions
Can I travel between all Caribbean islands by ferry?
No. Ferry networks are well developed in the Eastern Caribbean (Lesser Antilles, Virgin Islands, Trinidad–Tobago) but most larger Caribbean islands — Cuba, Jamaica, Puerto Rico, Hispaniola, Barbados — have no regular ferry connections and require flights to reach.
Who operates the ferry between Guadeloupe and Martinique?
L'Express des Iles is the main operator on this route, running high-speed catamaran services several times a week. The crossing takes around 3.5–4 hours.
Are there ferries in the Grenadines?
Yes — the Grenadine islands (Bequia, Mustique, Canouan, Mayreau, Union Island) are connected by Windward Islands Ferries and local water taxis from St Vincent. This is one of the best island-hopping-by-boat networks in the Caribbean.
How do I get from St Thomas to Tortola without flying?
Several ferry operators — including Speedy's, Native Son and others — run passenger ferries between St Thomas (USVI) and Road Town, Tortola (BVI). The crossing takes about 30–45 minutes. Bring your passport, as this is an international border crossing.
