A shared charter between two nearby islands can work out to $60 to $120 per person if you fill the boat. The practical upshot: budget $400 to $600 for inter-island transport if you plan to visit four or five islands.
A ferry from St. Lucia to Dominica costs about $50 each way and runs four days a week.
That single line tells you most of what you need to know about the Lesser Antilles. The islands are close together on a map. They are not close together in practice. You cannot hop between them the way you hop between Greek islands or Thai islands. The water between them is open Atlantic and Caribbean, the winds are steady, and the boats that cross are few.
This is the eastern edge of the Caribbean, the arc of small islands running from the Virgin Islands down to Trinidad. What follows is what the numbers actually look like on the ground.
The Geography That Sets the Cost
The chain runs roughly 700 miles north to south. Twenty-odd inhabited islands, depending on how you count. Some are independent countries. Some are British, French, Dutch, or American territories. That matters more than you’d think. A French island uses euros. A British one uses East Caribbean dollars. An American one uses US dollars. You cross a stretch of water two hours wide and the currency, the language, and the price of a beer all change.
The distances between islands are short. St. Lucia to Martinique is about 40 miles. Martinique to Dominica is about 60 miles. Guadeloupe to Antigua is roughly 100 miles. These are not long passages. The problem is not distance. The problem is that scheduled, affordable transport between them is thin.
Getting Between Islands
Flying between islands is common and expensive. A one-way flight from Antigua to St. Lucia can run $180 to $260. St. Lucia to Barbados, about 100 miles apart, often costs $150 to $220 one way. These are short flights on small planes, and the fares do not behave like the fares you’re used to. There is no meaningful budget airline competition on most of these routes.
Ferries exist on some legs and not others. St. Lucia to Dominica is around $50 each way, four days a week. Guadeloupe to Dominica and Guadeloupe to Martinique have regular services. Between many other pairs there is simply nothing scheduled. You fly or you don’t go.
The workaround is the inter-island cargo and passenger boats, and the occasional charter. A shared charter between two nearby islands can work out to $60 to $120 per person if you fill the boat. That requires other people, which requires luck.
The practical upshot: budget $400 to $600 for inter-island transport if you plan to visit four or five islands. If you stay on one island, that number drops to near zero.
What a Bed Costs
Accommodation is where the region surprises people in both directions. There is very little of the cheap backpacker infrastructure you find in Central America or Southeast Asia. No $8 dorm beds in most places.
A dorm bed, where it exists, runs $25 to $45 a night. Antigua, St. Lucia, and Barbados have a handful of hostels in that range. The smaller islands often have none at all.
A basic guesthouse room, private, with a fan and cold water, is $45 to $75. A room with air conditioning and hot water pushes to $80 to $120. Mid-range hotels start around $150 and climb fast.
The French islands are slightly cheaper on the low end because there is more small-scale local accommodation. Guadeloupe and Martinique have guesthouses at $50 to $80 that would cost $100 on a British or American island.
Camping is possible on several islands for $10 to $20 per person per night, but it is not widespread and not always safe to leave gear.
Food and Daily Spend
Food splits cleanly into two categories.
Cook your own and eat local, and you can eat for $15 to $25 a day. Markets on the French islands are notably cheap. A baguette, cheese, fruit, and a bottle of wine in Guadeloupe can come to under $12. On the British and American islands, groceries cost more because so much is imported. A week of basic groceries on Antigua runs $70 to $100.
Eat out and the number triples. A plate of local food at a roadside stall or small restaurant is $8 to $15. A sit-down meal at a mid-range restaurant is $25 to $40 per person before drinks. A beer at a bar is $3 to $6, with the French islands at the low end and the resort-heavy islands at the high end. A rum punch is $7 to $12.
A realistic daily budget, staying in dorm beds or cheap guesthouses, cooking some meals, eating local the rest, using buses, comes to $70 to $100 per day. That is the floor. Anyone telling you the Lesser Antilles can be done on $40 a day is describing a trip that involves very little movement and a lot of skipped meals.
Getting Around Each Island
Buses are the cheapest way to move on land and they are genuinely cheap. On St. Lucia, a bus across the island costs about $1.50. On Dominica, similar. On Antigua, $1 to $2. These are minibuses, they run on fixed routes, they stop when full, and they stop running in the early evening.
Taxis are the fallback and they are not cheap. A taxi from the airport to a town center is commonly $20 to $40. Fares are often fixed by zone rather than metered, so the price is the price.
For the run into town, a fixed-price transfer ends the meter anxiety.
Renting a car runs $40 to $70 per day, plus a local driving permit on some islands that costs $12 to $25. Fuel is around $4 to $5 per gallon on most islands, higher on the French ones.
Scooter rental is $25 to $45 per day and is a reasonable option on the smaller, flatter islands. On the mountainous ones, the roads and the traffic make it a bad idea.
Where the Money Goes Wrong
The single biggest budget error is assuming island-hopping works like it does elsewhere. It does not. A four-island trip with three inter-island flights can burn $500 on transport before you’ve paid for a single night’s sleep.
The second is underestimating food on the British and American islands. Imported groceries are expensive and restaurant prices reflect a tourism economy. Budget $30 a day for food minimum, and more if you want to eat out.
The third is arrival timing. Ferries and buses do not run late. A flight that lands at 6pm on a Sunday can leave you paying $40 for a taxi because the buses have stopped and the ferry left at 4.
The Shape of a Cheap Trip
Two islands, not five. Pick one French island and one British or independent island to see the price difference for yourself. Guadeloupe and Dominica, or Martinique and St. Lucia. Use buses. Cook breakfast and lunch, eat local for dinner. Take the ferry where it exists and skip the leg where it doesn’t.
That trip runs $85 to $110 per day all in, including the ferry. Two weeks comes to roughly $1,200 to $1,500 plus your flight to the region.
The Lesser Antilles are not a cheap destination. They are a specific one. The numbers reward you for staying still and punish you for moving. Plan accordingly and the region is workable on a real budget. Plan it like a Southeast Asia trip and you will be shocked at the bill.
