How to Get to the Rosario Islands
The Rosario Islands are just a 1–2 hour boat ride from Cartagena. Here’s how to get there:
- Public Boats: Boats leave daily from Muelle de la Bodeguita in Cartagena to all the islands between 8:00 AM and 9:00 AM. Prices vary depending on your destination, typically ranging from 60,000–100,000 COP ($15–25 USD) round trip.
Credit cards are not accepted for ticket purchases, so make sure to bring enough Colombian pesos to cover your expenses for the entire day.
- Private Boats: Ideal for groups or those seeking flexibility, private rentals are available at Cartagena’s marinas. Expect to pay between 700,000–1,500,000 COP ($175–375 USD) for the entire boat.
- Tour Packages: Many companies offer organized tours that include boat transport, lunch, and access to private beaches. Prices start at around 150,000 COP ($38 USD) per person.
Key Tips Before You Go:
- Port Tax: As of 2024, travelers must pay a port tax of 26,500 COP ($6 USD) at Muelle de la Bodeguita before boarding. They do not accept credit card, so bring enough pesos.
- Schedule: Boats generally return to Cartagena between 3:00 PM and 4:00 PM, and afternoon winds can make the ride choppy. Morning departures are recommended.
- Cash Only: Many islands do not accept credit cards, so carry enough Colombian pesos for food, activities, and entry fees.
- Pack Smart: Bring sunscreen, a towel, water shoes, and snorkeling gear to enhance your experience.

Isla Grande
Isla Grande, the largest of the Rosario Islands, offers lush greenery, beautiful beaches, and excellent snorkeling opportunities. Visitors can choose between luxury resorts and local village experiences.
How to Get There: Public boats can take you to Isla Grande in 45–60 minutes. They cost 60,000 COP ($30 USD).
Can You Stay Overnight? Yes. Accommodations range from budget options like Ecohotel Las Islas to high-end boutique stays like Hotel Isla del Sol, with prices from 250,000 COP ($60 USD) to over 1,000,000 COP ($250 USD) per night.
Crowds: While it’s one of the busier islands, you can find quieter areas if you explore further.
My Personal Experience: Isla Grande was hands down my favorite place I visited in Colombia. I went on a day trip, and the boat organization at the pier was surprisingly straightforward. Even though I traveled during the peak season in August, the crowds weren’t overwhelming—especially if you take the time to explore further away from where the boats drop you off.
What really stood out to me about Isla Grande was how accessible and affordable it was. It’s one of the cheapest and shortest boat rides from Cartagena, making it an easy escape to paradise. The crystal-clear water, stunning beaches, and tranquil vibe made it feel like a dream destination. I can’t recommend Isla Grande enough—it’s the perfect spot to experience Colombia’s tropical beauty without breaking the bank!

Isla Barú (Playa Blanca)
Famous for its powdery white sands and turquoise waters, Playa Blanca is technically part of the mainland but is often included in Rosario Islands tours.
How to Get There: Travel by public boat or take a tour from Cartagena (1 hour by car).
Crowds: Playa Blanca is extremely popular, especially on weekends and holidays. Arrive early to avoid the crowds.
Can You Stay Overnight? Yes. While most visitors go for day trips, accommodations like Hostel Casa en el Agua offer overnight stays.
Cost: Public transport costs 40,000–60,000 COP ($10–15 USD) round trip. Day tours range from 60,000–120,000 COP ($14–30 USD) including transportation back and forth from your accommodation and lunch.
My Personal Experience: To be honest, I wouldn’t recommend visiting Playa Blanca. Here’s why:
First, it’s incredibly crowded, especially during tourist seasons. No matter the day of the week, the beach is packed with people. It was honestly the most crowded beach I’ve ever seen, and the experience felt far from relaxing.
Second, unless you arrive super early, finding a free spot on the sand is almost impossible. This means you’ll likely need to rent lounge chairs. While they’re not very expensive, it’s still an added cost for an already underwhelming experience.
Lastly, for the price you’ll pay to visit Playa Blanca, I believe your money is better spent exploring other islands in the Rosario archipelago. Many of the other islands offer a much more enjoyable and serene atmosphere, making them far more worth your time and budget.
If you’re looking for a truly memorable experience, skip Playa Blanca and choose one of the other stunning islands instead!
