Rosario Islands: Private Boat Day Trip from Cartagena

Most people who book a boat to the Rosario Islands are actually picturing three different places at once: a coral reef, a floating bar, and a long white beach with a palm tree over a chair. All three exist, none of them are the same island, and the difference between a good day and a wasted one is almost entirely about which boat you get on. This page explains how the day works on a private boat, what the archipelago actually is, and the two things visitors most often get wrong before they book.

What the Rosario Islands actually are

The archipelago sits about an hour southwest of Cartagena and is not a resort strip. It is the core of the Parque Nacional Natural Los Corales del Rosario y de San Bernardo, a protected marine area of roughly 120,000 hectares covering coral reef, seagrass meadow and mangrove between the departments of Bolívar and Sucre. That protection is the reason the water is still clear enough to snorkel, and it comes with rules that apply to every visitor:

• No single-use plastic in the park.
• Nothing leaves with you: no shells, no starfish, no coral fragments.
• Life jackets on and seated while the boat is moving.
• An orientation briefing before you enter the protected area.
• Do not eat goliath grouper, sea turtle or queen conch if they are offered. All three are endangered and all three still turn up on informal menus.

The park charges an ecotourism fee on entry, collected on the day and separate from the tour price. Rates are published by Parques Nacionales Naturales de Colombia and change by sector, so confirm the current figure with your guide before you go.

The mistake almost everyone makes: Playa Blanca is not one of the islands

Playa Blanca, the beach in most of the photographs, is on the Barú peninsula, and you can drive there. It is grouped into island day trips because it is on the way back, not because it is an island. This matters for two reasons. If a long stretch of beach is what you want, you do not strictly need a boat at all. And if a cheap “island tour” spends most of its day at Playa Blanca, you have paid for a boat trip and received a beach transfer.

Our day goes to the reef first and uses Playa Blanca as the long, unhurried end of the afternoon, which is the order that makes sense once you know the difference.

Shared boat or private boat

This is the decision that determines the day, and it is worth being blunt about it.

• Shared boats run on a fixed timetable with forty to eighty passengers. You stop where the schedule says, for as long as the schedule says, and you leave when the last person is found. They are cheap and they work.
• A private boat carries your group only. You decide how long to stay at the reef, whether Cholón is a stop or a passing glance, and what time you head back. If somebody in the party does not swim, or a child needs a nap, or lunch runs long, the day absorbs it.

The tour on this page is the private version, with your own captain, crew and English-speaking guide.

What the day looks like

• Hotel pickup and the port, about 15 minutes. We collect you from your hotel and drive to Todomar CHL in Bocagrande. Your captain runs through the plan for the day before you board.
• Playa Grande, about an hour. Clear enough that you can see the coral formations from the surface. Snorkel over the reef or wade in from the sand. Bring your own mask if you are particular about fit; gear is not included.
• Cholón, about two hours. The island with the floating bars, and the loudest part of the day by a distance. Vendors come to the boat. If this is not your scene, say so and the time moves to the beach instead, which is the point of having your own boat.
• Playa Blanca on Barú, about four hours. A reserved spot with chairs under palm shade. This is the long, slow part: swim, eat, read, do nothing.
• Back to Cartagena, about an hour. Private transport is waiting at the pier to take you back to your hotel.

Eight hours door to door.

What is included, and what is not

• Included: private hotel pickup and drop-off, a private boat with captain and crew, a private English-speaking guide, and all-risk insurance.
• Not included: lunch, snorkel gear, the park’s ecotourism fee, and anything you buy from the vendors.

What to bring

• Reef-safe sunscreen, applied before you get on the boat. There is no shade for most of the crossing.
• A hat and sunglasses you do not mind losing overboard.
• Cash in pesos. The floating bars and the beach vendors are cash businesses and there is no reliable card signal.
• A dry bag or a waterproof phone case. Spray on the crossing is guaranteed.
• Your own snorkel mask if you have one.

Frequently asked questions

Is a day trip to the Rosario Islands worth it?

If you want to snorkel over living coral within an hour of a colonial city, yes. If what you actually want is a beach day, Playa Blanca on Barú is reachable by road and a boat adds cost without adding much. The trip is worth it for the reef, not for the beach.

How long does it take to get to the Rosario Islands from Cartagena?

About an hour on a fast private boat. Public and shared boats leaving from the Muelle Turístico de La Bodeguita take between one and two hours depending on the vessel, and stop more often.

Can I go to the Rosario Islands without a tour?

You can. Authorised operators run scheduled boats from the tourist pier in Cartagena, and Playa Blanca can be reached overland through the Barú peninsula. What you give up is control of the timetable and, at the cheaper end, any guarantee about the boat or the operator.

Is there an entrance fee for the national park?

Yes. Corales del Rosario y de San Bernardo is a national natural park and charges an ecotourism fee per visitor, collected on the day and not included in the tour price. Parques Nacionales publishes the current rates by sector.

What is Cholón?

A shallow bay off Barú where boats raft up around floating bars. It is busy, loud and popular, and it is either the best part of the day or the part you would rather skip. On a private boat that is your call rather than the timetable’s.
