Cartagena Islands Guide: Rosario Islands, Barú, Tierra Bomba & the Best Beaches Near the City
Cartagena sits at the gateway to some of the Caribbean's most rewarding island destinations. This guide covers the coral reefs of the Rosario Islands, the white sands of Playa Blanca on Barú, the quieter shores of Tierra Bomba, and the best beaches and nature trips you can reach by boat or road from the city.
The islands and beaches around Cartagena span a wide range of experiences, from the protected coral reefs of the Rosario Islands to the mangrove lagoons of La Boquilla just north of the city. Isla Barú, though technically connected to the mainland by road, is always marketed alongside the Rosario archipelago on account of Playa Blanca, widely considered the finest beach in the region. Getting the logistics right matters here: boat departure times, park fees, and tour inclusions vary significantly. Our best time to visit guide covers how the wet season (May to November) can affect sea conditions and small-boat departures, which is worth reading before you book.
✨ Pro tip
Book Rosario Islands day tours in advance during December to March (dry season). Shared lanchas from Muelle de la Bodeguita depart in the morning and return mid-afternoon. Missing the last boat back means arranging expensive private transport.
The Rosario Islands: Coral Reefs & Caribbean Water
The Rosario archipelago sits roughly 35 km southwest of Cartagena, with standard speedboat transfers taking 45 to 60 minutes from the Muelle de la Bodeguita. The islands are protected within the Parque Nacional Natural Corales del Rosario y de San Bernardo, and entry fees apply on top of boat costs. Budget shared lanchas run around US$15 to US$30 round trip, while mid-range day tours with lunch and snorkeling gear typically cost US$50 to US$90 per person.

FAQ
How do I get to the Rosario Islands from Cartagena?
Most visitors take a shared speedboat (lancha colectiva) or organized day tour from Muelle de la Bodeguita in Cartagena. Shared boats cost roughly US$15 to US$30 round trip and take 45 to 60 minutes. Group tours with snorkeling gear and lunch cost US$50 to US$90 per person. Private boat charters are available from around US$150 for small groups. Boats typically depart in the morning.
Is Isla Barú the same as the Rosario Islands?
No. Isla Barú is a large peninsula connected to the Colombian mainland by road and bridge, not an offshore coral island. It is often marketed together with the Rosario Islands because Playa Blanca, on Barú's western coast, is the most popular beach in the region. Many day tours combine both in a single itinerary.
What is the best time of year to visit the Rosario Islands?
December through April is the dry season, when sea conditions are calmer, visibility for snorkeling is best, and rain interruptions are rare. September and October see the heaviest rainfall and can produce choppy waters that affect small-boat departures. Most operators run tours year-round, but comfort and water clarity are best in the dry months.
Do Rosario Islands tours include park entry fees and snorkeling gear?
Not always. Lower-priced shared lanchas often cover transport only. Mid-range and higher-end group tours typically include snorkeling gear, lunch, and park fees, but you should confirm before booking. Read the inclusions list on whichever booking platform you use, as pricing varies significantly depending on what is covered.
Can I visit Playa Blanca on Barú without taking a boat tour?
Yes. Playa Blanca is accessible by road from Cartagena via Pasacaballos and the Barú peninsula. Shared minivans and private taxis make the trip, which takes about 1 to 2 hours depending on traffic. Arriving by road before the day-trip boats arrive (before 10 a.m.) means a quieter beach experience.
