Quick Facts About the Rosario Islands
|
Where Are The Rosario Islands & How To Get There?
The Rosario Islands sit just 35 kilometers southwest of Cartagena in the Caribbean Sea. You can reach these tropical islands by boat from three main departure points in Cartagena’s Old City and Bocagrande areas.
Transportation Options:
- Public speedboats – $15-25 round trip, fixed schedules, most budget-friendly
- Private boat rentals – $200-500 total, flexible timing, custom itineraries
- Tour packages – $40-80 per person, includes hotel pickup, lunch, and gear
Most boats take 45-90 minutes, depending on sea conditions and your chosen islands, with faster speedboats reaching closer islands like Isla Grande in under an hour.
Boats depart from Muelle Turístico (Tourist Pier), Bodeguita Pier, or Playa de los Pegasos throughout the day.
Best Time to Visit the Rosario Islands
Find the ideal months to enjoy calm seas, sunny skies, and perfect snorkeling conditions while avoiding crowds and rainy days.
- Dry vs. rainy seasons: The dry season runs December through April with calm seas and sunny skies, while the rainy season (May-November) brings afternoon showers and choppier waters.
- Best months for snorkeling & diving: December through March offer the clearest water visibility (up to 30 meters) and calmest sea conditions for underwater activities.
- Avoid high tourist seasons and public holidays by skipping December 15-January 15, Easter week, and Colombian holidays like Independence Day (July 20), when prices double and crowds peak.
Choosing the Right Tour or Package
Public tours vs. private charters: Public tours cost $40-80 per person with fixed schedules and crowded boats (30-40 people), while private charters run $200-500 total but offer flexible timing, custom itineraries, and intimate groups of 6-12 people.
What’s usually included: Most packages include round-trip boat transport, buffet lunch on the island, basic snorkeling gear, life jackets, and hotel pickup from Cartagena’s historic center or Bocagrande area.
How to choose a reputable operator: Look for operators with DIMAR maritime certification, 4+ star TripAdvisor ratings, modern boats with safety equipment, and clear cancellation policies – avoid street vendors offering suspiciously cheap deals under $30.
