Rosario Islands from Cartagena: Private Boat vs Shared, and What the Day Costs

Updated: 21 September 2026 · Written by Marta Fernández, founder of CABÚ Viajes, local operator in Cartagena de Indias (RNT 215668). We charter directly with the owners and captains — no agency fee.

In short: the Rosario Islands are a protected coral archipelago about 45 minutes by fast boat from a marina that sits ten minutes from the walled city. Going privately costs 850 to 3,800 USD for the boat for the day, not per person, plus a national park entry tax paid separately at the marina, per person. Going on a shared boat costs a fraction of that and buys a completely different day. This page is about which of the two you actually want.

What the Rosario Islands are

An archipelago of small islands and cays off the Colombian Caribbean coast, inside a national park created to protect the coral. That last part matters in practice: there is an entry tax, anchoring is restricted, and the water is clearer than anywhere you can reach from the city in under an hour. The islands themselves are low, green and mostly private — a mix of small hotels, day clubs and houses — with a few public beaches.

What you are buying with the trip is water. Cartagena's own beaches are brown, because a river meets the sea nearby. Forty-five minutes out, the colour changes completely. Almost every group that spends three nights or more in Cartagena gives one full day to this, and it is usually the day people remember.

Rosario or Cholón? They are not the same day

What it isProtected archipelago, clearer water, quieter anchorages, beach clubs and small hotelsA sheltered bay on Barú where boats raft up together; floating bars come to you
The dayA long lunch somewhere, swimming, snorkelling, a slower rhythmSocial, loud, everyone in the water between the boats
Distance from the marinaAbout 45 minutes by fast boatAbout 35 minutes
BusiestHoliday weeksEvery weekend, heavily
Who it suitsGroups with a range of ages, couples, anyone who wants the water more than the partyA group whose whole point is the party on the water

A full day can include both, and for most groups that is the right answer: Cholón for a couple of hours in the middle of the day, the islands for lunch and the swim. Ask for it when you book — it changes the route, not the price.

Private boat or shared boat

This is the real decision, and the honest version is that the shared boat is the better choice for some groups.

  • Shared boat. You buy seats on a scheduled departure. Cheap per person, fixed schedule, a fixed stop, and you go where the boat goes. For two to four people, or for a group on a tight budget, it is sensible and we will say so rather than sell you a charter.
  • Private charter. You take the whole boat: your departure time, your route, your music, your stops, and you leave when you decide. 850 to 3,800 USD for the boat depending on size — 850–1,500 for a 36–40ft speedboat comfortable for up to about twelve, 1,500–2,500 for a 45–50ft for fifteen to twenty, 2,500–3,800 above that.

Because the charter is billed per boat, the arithmetic flips with group size: that same 36–40ft boat is 250 USD each across six people and 125 each across twelve. From around eight people a private boat usually costs little more than the shared seats and buys a day that is yours. Below that, it does not.

The full charter page has the prices by boat size, what is included, and — importantly — what a "yacht" actually means in Cartagena, because most of the fleet advertised that way is a 36 to 48-foot speedboat.

What the day costs, beyond the boat

ItemHow it is charged
National park entry taxPer person, paid at the marina on the day. It is not ours to include, and any quote that hides it inside the boat price is hiding something
Private charter850–3,800 USD per boat, by size, for a full day of about eight to nine hours
Beach clubA minimum spend per person, separate from the charter. Worth knowing the number before you arrive rather than at the table
Food and drink on boardQuoted separately, or brought with you
Snorkelling gear, water toysWhere the boat carries them; not every boat does

When to go, and what moves the day

December to April is the dry season and the most reliable weather. January and February bring a steady breeze that makes the heat easier on land and the sea choppier on the way out — a 36ft boat feels that, a 50ft boat much less. May to November is the rainy season: afternoon showers, lower prices, and the occasional day when the port refuses clearance.

That last point is the one that catches groups out. If the captaincy refuses the port clearance for sea conditions, the day moves. It is not negotiable and it is a good thing — it is the mechanism that keeps boats from going out when they should not. The practical consequence is simple: put the island day early in the trip, never on the last morning, so there is a spare day to move it to.

What we check before a boat goes in a quote

US travel advice for Colombia warns specifically about small tourist boats to the islands, and the warning is fair: the fleet is large and not all of it is compliant. Four things, in writing, every time:

  1. The captain's licence, valid and in his own name.
  2. Passenger liability insurance on the vessel, not just hull cover.
  3. The port clearance (zarpe) for that day.
  4. Maximum legal capacity, with your group fitting inside it and the crew counted.

We send all four with the quote. If another operator will not, that answer is the information you needed.

Frequently asked questions

How far are the Rosario Islands from Cartagena?

About 45 minutes by fast boat from a marina in the city, and that marina is about ten minutes by car from a house inside the walled city. Cholón, the sheltered bay on Barú, is closer at around 35 minutes. There is no long road transfer to reach the boat, which is a real advantage over Caribbean destinations where the charter fleet sits an hour from where you sleep.

How much does a day trip to the Rosario Islands cost?

On a shared boat you buy seats on a scheduled departure and it is cheap per person. Privately, the boat is 850 to 3,800 USD for the day depending on size — 850–1,500 for a 36–40ft up to about twelve people, 1,500–2,500 for a 45–50ft for fifteen to twenty, 2,500–3,800 above that — billed per boat rather than per person. The national park entry tax is paid separately at the marina, per person, in both cases.

Is a private boat worth it, or should we take a shared one?

From around eight people a private charter usually costs little more than the shared seats and buys your own departure time, route and stops. The same 36–40ft boat is 250 USD each across six people and 125 each across twelve. For two to four people, or on a tight budget, the shared boat is the sensible choice and we will tell you so rather than sell you a charter.

Rosario Islands or Cholón?

The Rosario Islands are the protected archipelago: clearer water, quieter anchorages, beach clubs and a long lunch. Cholón is the sheltered bay on Barú where boats raft up together and floating bars come to you — social and loud, and very busy at weekends. A full day can include both, and for most groups that is the right answer.

Is there an entrance fee to the Rosario Islands?

Yes. The islands sit inside a national park and there is an entry tax charged per person, paid at the marina on the day of departure. It is charged whether you go privately or on a shared boat, and it is not included in a charter price. Be careful with any quote that gives one number and does not say the park tax is separate.

What happens if the weather is bad on our island day?

If the captaincy refuses the port clearance for sea conditions, the day moves rather than going ahead. That is the mechanism that stops boats going out when they should not. It is why we put the island day early in an itinerary and never on the last morning: it leaves a spare day to move it to. The rainy season runs May to November.
