The Day Trips From Saint Lucia That Are Worth the Early Start
Martinique, Dominica and the Grenadines Compared Honestly
My guide to the best day trips from Saint Lucia including Martinique, Dominica and the Grenadines, with real ferry costs, timings and which one suits your travel style.
Day Trips from Saint Lucia The Honest Insider Guide
I have spent more time exploring Saint Lucia and its neighboring islands than I can count, and I can tell you with absolute certainty that some of my best Caribbean memories happened on day trips from this island. When people ask me about day trips from Saint Lucia, they usually assume you need to stay put in Castries or Soufrière. That is simply not true. From Saint Lucia, you can reach Martinique, Dominica, Saint Vincent, and the Grenadines within a short ferry ride or quick boat journey. I have done these trips multiple times, and I am going to give you the real story about which ones are actually worth your time and which ones you should skip.
The Quick Answer: The best day trips from Saint Lucia are Martinique (stunning beaches and French culture), Dominica (the most dramatic nature I have ever seen), and the Grenadines islands like Bequia and Union Island (pristine beaches and island charm). Ferry schedules are reliable, prices range from $40 to $150 per person depending on destination, and you can realistically do a meaningful day trip to any of these islands. Book ferries a day or two in advance, bring your passport, and expect to spend at least four to five hours on your chosen island to make the trip worthwhile.
Martinique The Caribbean's Most Sophisticated Neighbor
I fell in love with Martinique the first time I took the ferry from Saint Lucia, and honestly, it remains one of my favorite day trip destinations in the entire Caribbean. The ferry ride itself takes about 30 to 40 minutes from Castries, and when you arrive in Fort de France, you step into a completely different world. This is not a typical Caribbean island experience. Martinique has French sophistication, incredible food, and some genuinely beautiful beaches that rival anything in Saint Lucia.
In my experience, most visitors spend their day in Fort de France exploring the historic colonial architecture, wandering through the central market, and eating at waterfront restaurants. The town itself has real character compared to other Caribbean capitals. I have walked the streets multiple times and never felt bored. The Musée de la Pagerie is worth an hour if you care about history, but honestly, I usually skip it and spend more time eating and exploring the neighborhoods.
The Beach Worth the Drive
The real gem is the beach at Les Salines, which I consider one of the top three beaches in the Lesser Antilles. It is about 45 minutes south of Fort de France by rental car or taxi, but it is absolutely worth the effort. The sand is impossibly fine, the water is crystalline, and it feels far less crowded than many Caribbean beaches I have visited. I have spent entire afternoons here doing absolutely nothing, and it has been perfect every single time.
Skip the tourist restaurants in Fort de France and eat at the street food stalls near the market. I had the best accras and fresh fish cakes of my life from a woman with a blue cart. A full meal costs about $8 to $12, and the food is infinitely better than anything you will find at a tourist trap.
Practical details: The express ferry costs $55 to $65 per person round trip and runs twice daily (morning and afternoon departures). You need a valid passport. Rent a car at the port for about $35 to $45 per day, or negotiate with a taxi driver for a half day rate (usually $50 to $70 for four hours). Bring euros or US dollars because ATMs in the port area can be unreliable. The best day trip window is morning departure at 7:00 AM with return at 6:00 PM, giving you a solid seven to eight hours on the island.
Martinique uses euros in addition to local currency, which trips up many visitors. Also, the roads in Martinique can be chaotic and poorly marked. If you are not comfortable driving in unfamiliar places, definitely stick with a taxi or book an organized tour rather than renting a car yourself.
Dominica Nature's Most Dramatic Island
When I first took a day trip to Dominica, I was genuinely shocked by how wild and untamed it felt compared to other Caribbean islands. Dominica has rainforests, volcanic peaks, and natural pools that look like something from a fantasy film. If you are the type of traveler who gets bored lying on a beach all day (I sometimes am), Dominica is your day trip.
The ferry from Saint Lucia takes about 90 minutes to reach Rosalie Bay on Dominica's east coast. I am not going to sugarcoat it: this ferry ride can be rough. I have had smooth journeys and I have had rides where I genuinely questioned my life choices. If you are prone to seasickness, take a medication beforehand. The payoff is absolutely worth it though.
Titou Gorge and the Waterfalls
The main draw for me has always been Titou Gorge, a natural swimming hole nestled in a dramatic gorge surrounded by rainforest. I have swum in that pool probably eight times, and it never gets old. The water is cool and refreshing, the air smells like earth and vegetation, and you genuinely feel like you are in another world. The drive from the port takes about 45 minutes, and entrance to the gorge is about $3 per person. Parking is $2.
I have also spent day trip time exploring the town of Rosalie itself, walking through the botanical gardens, and soaking in the natural sulfur springs. Dominica does not have the polished, developed feel of Saint Lucia. It is rawer and more authentic, which I personally prefer, but I understand some travelers find it less comfortable.
Hire a local guide in Rosalie Bay for a few hours. I met a man named Marcus who took me to hidden waterfalls that no tourist ever sees and shared his knowledge about the island's history and ecology. He charged about $30 per hour, and it was worth triple that. Ask at your ferry arrival point or hotel to find legitimate guides.
Practical information: The ferry from Castries is $50 to $60 round trip and takes 90 minutes each way. You can only realistically spend four to five hours on the island if you take the standard day trip ferries. Rent a car at the port for about $40 per day, or hire a driver for $50 to $70. Everything on Dominica is incredibly affordable. A full meal at a local restaurant costs $8 to $15. Bring plenty of water and wear good hiking shoes because you will be walking through muddy terrain.
Dominica is underdeveloped compared to Saint Lucia, and some infrastructure is not as smooth. The roads have potholes, restaurants might not have your first choice available, and the overall experience is less polished. If you prefer everything perfectly organized and predictable, Dominica might frustrate you. But if you want authenticity and adventure, it is perfect.
The Grenadines Island Hopping at Its Finest
I have made several day trips to the Grenadines islands from Saint Lucia, and these are genuinely some of the most beautiful and underdeveloped islands in the Caribbean. Bequia and Union Island are the most accessible for day trips, and both offer something completely different from the Saint Lucia experience.
Bequia is my preferred Grenadines day trip destination. The ferry takes about 90 minutes to an hour and a half depending on sea conditions, and when you arrive, you step into a sleepy Caribbean island that feels frozen in time. The island has just a few thousand residents, and it has maintained an authenticity that is increasingly rare in the Caribbean. I have walked the main beach multiple times, and I have always felt like I was discovering something special.
Bequia Versus Union Island
Princess Margaret Beach is the main attraction, and it is genuinely lovely. The sand is soft, the water is warm, and the pace of life is incredibly slow. There are beach bars where you can spend an afternoon for the price of a few drinks and some food. I have done this probably four times, and it never gets old. The island also has a few small restaurants where the food is simple but delicious. I had conch salad at a beach shack that ranked in my top ten Caribbean meals ever.
Union Island is a bit more developed than Bequia and offers better opportunities for snorkeling and water sports. I have taken a catamaran tour from Union that visited five different islands and three snorkel sites in a single day, and it was genuinely one of the best water experiences of my life. The visibility was incredible, the coral was healthy, and we saw fish and sea turtles I had never seen before.
On Bequia, skip the obvious beach bar restaurants and eat at one of the family-run spots in the residential areas. I found a woman named Dorothy who cooks her kitchen's lunch specials out of her home, and a plate of fresh fish with plantains and provisions costs $7. Ask locals where they eat breakfast, and you will find the real food.
Ferry details: The ferry to Bequia costs $40 to $50 round trip and runs once daily in each direction from Saint Lucia. The ferry to Union Island is similar pricing. These ferries are smaller and slower than the Martinique ferry, so expect a rougher ride in anything but calm seas. You get roughly four to five hours on whichever island you choose, which is enough time to swim, eat, and explore a bit.
The ferry schedules are reliable, but heavy rain or rough seas can cause cancellations. Always check the day before your planned trip and have a backup plan. I once planned a Bequia day trip and the ferry was cancelled, forcing me to explore Saint Lucia instead. It worked out fine, but it is good to know.
Ferry Details
One important note: The Grenadines islands are considerably less developed than Saint Lucia. Restaurants might have limited menus, ATMs are not always available, and activities are quieter and simpler. If you are looking for adventure and authenticity, this is perfect. If you prefer every amenity at your fingertips, you might find them underwhelming.
Planning Your Day Trip Logistics
I have taken these ferries and day trips dozens of times, and I have learned some practical lessons that will make your experience better. First, always bring your passport. Caribbean ferry services have become more rigorous about documentation, and I have watched travelers get turned away because they did not have proper ID.
Second, book your ferry tickets at least one day in advance during high season (December through April) and at least a few hours in advance during low season. Ferry schedules can change based on demand and weather. I always confirm my return ferry the day before to make sure it is running. Once I showed up to catch a ferry only to find it had been cancelled due to rough seas, forcing me to hire a private boat at significant expense.
Third, plan your day trip with realistic timing. Ferry travel takes significant time. If you are taking a 90-minute ferry each way, you have really only got about four to five hours on your destination island. I recommend spending a full day (leaving early morning, returning late evening) rather than a half day trip because the ferry travel eats up so much time otherwise.
Money and What To Pack
Fourth, bring cash. Not all establishments on these islands accept cards, and ATMs are not always reliable. I always withdraw EC dollars (East Caribbean dollars) or bring US dollars and have them exchanged. Most small restaurants, beach bars, and vendors expect cash.
Fifth, pack sunscreen, water, and a light rain jacket. Even if the forecast looks clear, Caribbean weather changes fast. I have been caught in sudden rainstorms more times than I can count, and I have learned to always have a jacket available. Sunscreen is obviously essential, and bringing your own is cheaper than buying it on the islands.
Wear water shoes or reef shoes on the ferry ride itself. I cannot tell you why, but something about the motion of Caribbean ferries makes many people feel queasy. Having comfortable shoes you can slip on and off helps. Also, sit on the upper deck if possible for better air circulation and less motion sensitivity.
Which Day Trip Is Right For Your Travel Style
I have taken all of these day trips multiple times, and they appeal to very different travelers. Let me be honest about which one fits which type of person.
If you want a sophisticated, polished travel experience with excellent food and French colonial culture, choose Martinique. You will feel like you are traveling in a European destination, not a typical Caribbean island. The infrastructure is reliable, the restaurants are excellent, and you will have a smooth, predictable day.
If you want adventure, natural beauty, and an authentic Caribbean experience away from tourist polish, choose Dominica. You will hike through rainforests, swim in natural pools, and feel like you are discovering something real. Expect things to be less organized and more raw, but infinitely more memorable.
If You Want a Slow Island Day
Choose Bequia in the Grenadines. It is the smallest and gentlest of the three, and the appeal is that almost nothing is scheduled. You walk from the ferry into Port Elizabeth, eat at a family run spot away from the waterfront, spend a few hours on Princess Margaret Beach and get back on the boat. There is no headline attraction and that is exactly the point. I go when I want the trip to lower my heart rate rather than fill a camera roll.
My Honest Recommendation
If this is your first Saint Lucia trip and you have seven days or fewer, skip the day trips entirely and spend the time properly exploring the island you already flew to. If you are on a longer stay or a repeat visit, take Dominica. It is the one that has stayed with me, and it is the one that feels least like the Caribbean you can get anywhere else.
Book your return ferry for the later of the two afternoon sailings rather than the earlier one, then plan your day as though you are taking the earlier. That gives you a genuine buffer if a guide runs long or a bus does not turn up, and if everything goes smoothly you get an extra two hours on the island instead of sitting in a terminal. It costs nothing and it has saved two of my day trips.

The questions I get asked most often, answered honestly from personal experience.
My Final Thoughts on Saint Lucia Day Trips
I want to be honest about something first. If you only have five days in Saint Lucia, do not spend one of them on another island. Saint Lucia itself has more than enough to fill that time, and a day trip costs you two ferry crossings and most of your daylight.
On a longer trip they become genuinely worthwhile, and I would pick Martinique for the food and the polish or Dominica for the raw nature. Book the ferry ahead, take the early crossing, and treat it as a full day rather than something you squeeze around a lunch reservation.
