Islas del Rosario: The Real Cost of the Island Day

A shared speedboat is the default and the cheapest seat, but it runs to a fixed schedule and a fixed stop list set by the operator, not by you. A private charter costs more per person for a small group but lets you pick the islands and the timing, and the math flips once your group is large enough. A catamaran sits in between: slower than a speedboat, more expensive than either shared option, and the only one of the three with real shade and deck space for a full day.

The rule of thumb from operator pricing: a private charter starts costing about the same per head as a shared tour once a group reaches roughly 9 people, and a catamaran only beats a private speedboat on cost per head once a group reaches about 18. Below those thresholds, the shared speedboat tours in the table above are the cheaper way to see the same water. None of the private-charter figures here come from a published price board.

They are aggregator-reported quotes from a single source, so treat them as a starting range to negotiate from, not a fixed rate.

Isla Grande: the largest island, and a full day on its own

Isla Grande is the biggest island in the archipelago, reached by boat from Muelle de la Bodeguita in about 1.5 hours each way. The reported round-trip fare is $47.60 (150,000 COP), and the national park entry of $7.30 (23,000 COP) is billed as a separate line, not folded into the boat price. At three hours of transit alone, this is not something you bolt onto a standard Rosario tour.

It is its own full day. It is also where Pablo Escobar once kept a private compound, a mansion and outbuildings that some tours still point out from the water.

Santa Cruz del Islote: reached through the San Bernardo run, not the Rosario one

Santa Cruz del Islote sits in the San Bernardo archipelago, a separate cluster from the Rosario islands, and is widely reported as the most densely populated island on Earth for its size, packing several hundred residents onto about 1.2 hectares. Boats there add a separate islet charge of $3.17 (10,000 COP) on top of whatever the boat itself costs. Reaching it from Cartagena directly runs about 2.5 hours each way at roughly $31.70 (100,000 COP) per person, or about $88.80 (280,000 COP) on an organized tour.

From Tolú: cheaper and faster for San Bernardo, slower for a Cartagena base

Multiple sources agree that departing from Tolú or Rincón del Mar, both well north of Cartagena on the coast, is cheaper and faster than going to San Bernardo from Cartagena itself. From Tolú, a mototaxi to the dock runs about $1.27 (4,000 COP), and the boat to Isla Múcura or Isla Tintipán costs around $12.69 (40,000 COP) for a roughly one-hour crossing, with boats leaving daily around 8:00 a.m. A round trip from Tolú or Rincón del Mar runs $19.03 to $31.70 (60,000 to 100,000 COP).

None of this helps a traveller based in Cartagena for a single day. It only makes sense as a separate trip up the coast, or as part of a longer Caribbean coast itinerary.

None of the three routings below is a half-day option. The Rosario Islands sit far enough offshore that every version of this trip eats a full day, and the difference between them is what you skip, not how long you're gone.
