The Rosario Islands are the best reason to book an extra day in Cartagena. A 45-minute boat ride from the city marina and you are somewhere that looks nothing like the Caribbean coast you just left: turquoise water, white sand, coral reefs, and beaches that feel genuinely remote despite being less than an hour from one of South America's most visited cities.
Going by private boat changes the experience entirely. You choose your own stops, set your own pace, and spend the whole day with your group rather than 50 strangers from a tour bus and a group boat. For a bachelor party, a wedding weekend, or any group trip to Cartagena, a private day at the Rosario Islands is the centerpiece that everything else is planned around.
This guide covers everything you need to know before you go: what the islands actually look like, where to stop, what to do, how long it takes, what it costs, and what Two Travel Concierge handles so the day runs perfectly.

What Are the Rosario Islands?
The Rosario Islands (Islas del Rosario) are a coral archipelago located in the Caribbean Sea southwest of Cartagena, forming part of the Corales del Rosario y San Bernardo National Natural Park. The park was established in 1977 and protects one of the most important coral reef systems on the Colombian Caribbean coast, covering approximately 120,000 hectares of marine and terrestrial environment.
The archipelago consists of more than 20 small islands ranging from densely vegetated coral cays with mangroves and palms to tiny sand formations that are barely above water at low tide. The larger islands including Isla Grande have established beach clubs, small resorts, and restaurants accessible by private boat.
The water around the Rosario Islands is the clearest in the Cartagena region, a direct result of the national park protection that limits development and motorized traffic in the most sensitive reef zones. Visibility for snorkeling regularly reaches 10 to 15 metres in calm conditions, and the coral gardens host a diverse range of fish, rays, and marine life.
Why the Rosario Islands Are Better Than Cartagena Beach
Cartagena's city beaches in Bocagrande and the Laguito area are convenient but not the Caribbean experience most visitors come for. The water is not clear, the beach is not particularly wide, and the city noise and activity never fully disappear.
The Rosario Islands are the genuine Caribbean version. The difference in water clarity alone is striking: from murky brown near the city to crystal turquoise within 30 minutes on the water. Add white sand, reef snorkeling, and the sense of genuinely being out at sea, and it is a completely different experience.
Private Boat vs Group Tour: Why Private Wins for Group Travel
Group boat tours to the Rosario Islands depart daily from the Muelle de la Bodeguita in Cartagena's Old City and can carry 40 to 80 passengers. They are affordable (roughly $50 to $80 USD per person including lunch) and they do reach the islands. But the experience is significantly different from a private charter.
What a Group Tour Looks Like
- Depart on a schedule set by the operator, not your group
- Share the boat with 40 to 80 strangers from multiple hotels and nationalities
- Visit the same three stops in the same order as every other group tour
- Fixed lunch at a designated restaurant with limited menu choices
- Return on the operator's schedule, not when your group is ready
What a Private Boat Looks Like
- Depart when your group is ready, from the marina closest to your villa
- The boat is yours: your group, your crew, your captain for the entire day
- Choose your own stops, time at each stop, and order of the itinerary
- Swim directly off the back of the boat wherever you anchor
- Pre-stocked cooler with your drinks, lunch at the beach club of your choice
- Return when your group decides, or when the sunset says it's time
For a bachelor party or any group of 8 or more, the per-person cost of a private charter catamaran reaches or beats many group tour prices while delivering an experience in a completely different category. Two Travel's Cartagena boat packages are structured to make private the obvious choice for any group of this size.
The Best Stops on a Rosario Islands Private Boat Day
A well-sequenced Rosario Islands day covers three main stops, each with a distinct character. Your captain will know conditions on the day and can adjust the sequence based on wind, sea state, and timing.
Coral Reef Snorkeling (National Park Zone)
The first stop on most private itineraries is one of the protected reef zones within the national park, typically in the waters around the outer Rosario Islands. This is where the best coral and marine life concentrates, and where visibility is highest in the morning before afternoon wind stirs up the surface.
Snorkel gear is included with most private charters, and the captain anchors over a reef section appropriate for the group's snorkeling experience. Experienced swimmers can drift freely over the coral; less confident swimmers can stay close to the boat. The reef system has been recovering steadily under national park protection and hosts healthy coral alongside reef fish, rays, and sea turtles on some visits.
A national park entry fee applies per person for the reef snorkeling zone. This is charged on the water or at the entry point and is not typically included in the base boat charter rate. Two Travel includes this fee in its packaged pricing to eliminate confusion on the day.
Isla Grande
Isla Grande is the largest island in the Rosario archipelago and the main destination for beach club visits. Several well-run beach clubs on Isla Grande offer sunbeds, shading, fresh seafood and Caribbean food, and bar service directly on the sand. Lunch here is one of the highlights of the day: fresh grilled fish or ceviche, cold beer, and the sound of water on all sides.
Most groups spend 2 to 3 hours at Isla Grande, combining a beach club lunch with swimming in the shallow, clear bay and exploring the island's edges on foot. The beach clubs accommodate large groups without reservation when booked through a concierge, and Two Travel pre-arranges table placement and menu service as part of the Rosario Islands package.
Playa Blanca (Baru)
Playa Blanca on the Baru peninsula is a separate destination from the Rosario Islands, located on the Colombian mainland coast south of Cartagena. It is one of the most photographed beaches in Colombia, with a wide white sand beach, gentle surf, and a line of vendor huts selling food and drinks. Many private charters add Playa Blanca to a Rosario Islands day as an afternoon stop before the sunset return to Cartagena. Read the full guide to Cartagena Islands and Baru for a detailed comparison of both destinations.
The Baru stop adds approximately 45 minutes of transit time to the day but delivers a beach experience that is distinctly different from the island environment of the Rosarios. Groups with a full departure of 9am or earlier can comfortably do both without feeling rushed.
Floating Bar Stops and Anchored Swimming
In between the main stops, most private charters spend time anchored in a calm bay or sheltered spot where the group can swim directly off the back of the boat. This is often where the informal highlights happen: the cooler is open, the music is on, and the whole group is in the water together with nothing but blue Caribbean Sea in every direction. Two Travel can arrange a floating drinks setup, a private bartender on the boat, or a pre-stocked drinks package depending on the group's preference.

How Long Does It Take to Get to the Rosario Islands?
The crossing time from Cartagena to the Rosario Islands depends on which boat you are on and which island you are heading to.
By Private Speedboat or Lancha
A private lancha or speedboat covers the distance from the marina to the nearest Rosario Islands reef zones in approximately 45 to 60 minutes. The crossing involves open water and can be choppy in the afternoons, particularly during the dry season when easterly winds pick up from December through April.
By Private Catamaran
A catamaran takes 60 to 90 minutes to reach the Rosario Islands due to its lower top speed compared to a speedboat, but the crossing experience is considerably more comfortable. The twin-hull design absorbs chop significantly better than a monohull or open speedboat, and the group can move freely around the deck during the crossing rather than gripping a rail.
By Group Ferry
The public ferry from Muelle de la Bodeguita takes 60 to 90 minutes to reach the islands and operates on a fixed schedule. This is the budget option and an entirely different experience from a private charter.
What Does a Rosario Islands Private Boat Day Cost?
The cost of a private Rosario Islands boat day from Cartagena depends on the vessel type and group size. Based on current 2026 market rates, a private lancha for 8 to 12 people runs approximately $680 to $950 USD for a full day. A private catamaran for 10 to 20 people runs approximately $1,200 to $2,500 USD for a full day depending on vessel size and season. Read the detailed breakdown in the full Cartagena boat rental cost guide for per-person figures by group size.
Additional costs to budget for on a Rosario Islands day include the national park entry fee (approximately $10 to $15 USD per person, charged separately), beach club food and drinks at Isla Grande, and gratuity for the captain and crew.
Two Travel's Rosario Islands packages bundle the boat charter, national park entry, beach club coordination, and transfer logistics into a single price so there are no surprises on the day.

What to Bring on Your Rosario Islands Boat Day
- Reef-safe sunscreen (non-reef-safe sunscreen is prohibited in the national park zone and causes coral damage)
- Swimwear and a change of clothes for the return
- Waterproof phone case or dry bag for electronics
- Cash in Colombian Pesos for the national park fee and any purchases at smaller island stops
- Sunglasses, hat, and light cover-up for extended time on the boat deck
- Motion sickness medication for anyone sensitive to open water crossings
- Reusable water bottle, as staying hydrated in Caribbean heat is important
Two Travel provides a pre-departure checklist to all groups as part of the booking confirmation so no one arrives at the marina having forgotten sunscreen or cash.
Best Time to Visit the Rosario Islands
The Rosario Islands can be visited year-round, but conditions vary meaningfully across seasons.
Dry Season: December Through April
The dry season brings the clearest skies, calmest mornings, and the highest visitor numbers. Snorkeling visibility is excellent in the morning before afternoon easterly winds build. The sea can become choppy in the afternoon during the dry season, which is why morning departures are strongly recommended. This is peak pricing season for boat charters.
Shoulder Season: May Through July
May through July offers a good balance of manageable weather and lower boat charter prices. Rainfall is light and brief, typically afternoon showers that pass quickly. The islands are quieter than peak season, which means less competition for beach club spots and a more relaxed atmosphere.
Wet Season: August Through November
August through November is the rainiest period, with the heaviest rainfall typically in October and November. Boat days are still possible, and many groups have excellent Rosario Islands days in this period. Crossings can be rougher, and it is important to confirm sea conditions with the captain the day before departure. Charter prices are at their lowest.
Frequently Asked Questions
Do we need to know how to snorkel to visit the Rosario Islands?
No. The boat anchors in calm, relatively shallow water for the snorkeling stop and the captain or crew can assist anyone new to snorkeling. Many visitors float at the surface using the snorkel and mask to look down at the reef without diving. Life jackets are on board for anyone who wants extra flotation.
Can we visit the Rosario Islands and Baru Playa Blanca on the same day?
Yes, and it is one of the most popular itineraries Two Travel coordinates. A 9am departure gives you enough time to snorkel at the Rosario Islands, stop at an Isla Grande beach club for lunch, transit to Playa Blanca for an afternoon beach stop, and still make the sunset crossing back to Cartagena by 6pm. The key is an early departure to avoid rushing any stop.
Is the Rosario Islands national park fee included in the boat charter?
In most standard charter quotes, the national park entry fee is charged separately on the water and is not included in the headline charter price. It typically runs $10 to $15 USD per person. Two Travel includes this fee in its packaged Rosario Islands itineraries to give groups a single all-in price with no waterside surprises.
