Where are the Rosario Islands?

The Islas del Rosario sit approximately 35 kilometers southwest of Cartagena in the Caribbean Sea, within the Corales del Rosario y de San Bernardo National Natural Park. The archipelago consists of 27 islands ranging from tiny uninhabited cays to larger islands with hotels, beach clubs, and marine research stations. The islands are part of Bolivar Department and are administered as a protected marine area by Colombia’s national parks authority.

The closest island, Isla Grande, is the largest and most developed, with several eco-hotels and day-trip beach clubs. Other popular stops include Isla Baru (technically a peninsula but grouped with the Rosario Islands for tourism), Isla del Pirata, Isla del Encanto, and the Oceanario (a small marine aquarium popular with families).

How to get to the Rosario Islands from Cartagena

Private boat charter — the best way

A private boat from Colombia Luxury Group is the most comfortable, flexible, and exclusive way to visit the Rosario Islands. Your captain navigates directly to the best snorkeling spots, uncrowded beaches, and hidden coves that public ferries skip entirely. You set the schedule, choose your stops, and travel with your own group.

Private speedboats reach the Rosario Islands in 35-45 minutes. Catamarans and larger yachts take 60-75 minutes but offer a much smoother, more spacious ride. Full-day charters (8 hours) include captain, crew, fuel, ice, sound system, and snorkeling gear. Prices start at $1,499 for a speedboat (8-15 guests), $2,499 for a yacht (15-25 guests), and $2,999 for a catamaran (20-40 guests).

Public ferry — the budget option

Shared lanchas (speedboats) depart from the Muelle de la Bodeguita in Cartagena starting at 8:00 AM. Round-trip tickets cost approximately $25-$40 USD per person. The ride takes 45-60 minutes. Ferries typically stop at Isla Grande or Playa Blanca on Baru. The experience is crowded (30-40 passengers per boat), has fixed schedules, and offers no flexibility on stops. You’ll wait at a designated beach club until the return ferry at 3:00-4:00 PM.

Private vs public comparison

The public ferry costs $25-$40 per person but limits you to one beach with fixed timing. A private speedboat for 10 guests costs approximately $150 per person and gives you a full day with multiple stops, privacy, your own music, and the freedom to explore where the crowds aren’t. For groups of 4 or more, private charter delivers dramatically better value per dollar spent.

Best things to do on the Rosario Islands

Snorkeling and diving

The Rosario Islands sit within a protected coral reef system, making them one of the best snorkeling destinations in the Colombian Caribbean. The clearest water and healthiest reefs are found around the smaller, less-visited islands south of Isla Grande. Your yacht captain knows exactly where to anchor for the best visibility — typically 15-25 feet on a calm day. Bring your own gear or use the equipment included with every Colombia Luxury Group charter.

Beach hopping

With 27 islands, you’re not limited to one beach. Private boat guests can visit multiple islands in a single day: start at a secluded beach on Isla Grande, move to Playa Blanca on Baru for lunch, and finish at a quiet cove for sunset. Public ferry passengers are stuck at whichever beach their operator chooses.

Cholon — the floating party

Cholon is a shallow bay on Isla Baru where dozens of boats anchor for a massive floating party every weekend. Music blasting from every yacht, vendors paddling between boats selling fruit and drinks, and a festive atmosphere that’s become legendary among Cartagena visitors. It’s the Caribbean equivalent of a pool party — on the ocean. Bachelor and bachelorette parties often make Cholon their main stop.

Oceanario (Rosario Islands Aquarium)

A small marine aquarium on Isla de San Martin de Pajarales featuring dolphins, sharks, sea turtles, and a touch pool. Popular with families traveling with children. Entrance fee is approximately $10-$15 USD. Accessible by both public ferry and private boat.

Kayaking and paddleboarding

The calm, protected waters between the islands are perfect for kayaking and stand-up paddleboarding. Many beach clubs rent equipment, and some yacht charters include paddleboards. Early morning, before the tour boats arrive, offers the most peaceful paddling conditions.

Best time to visit the Rosario Islands

The dry season from December through April offers the calmest seas, clearest water, and most reliable sunshine. January and February are peak months with the best snorkeling visibility. Water temperatures stay between 80-84°F year-round. The rainy season (May-November) brings short afternoon showers but also fewer crowds and lower prices. Seas can be rougher in October-November, making catamaran charters preferable for their stability.

How much does a Rosario Islands trip cost?

Budget (public ferry): $40-$80 per person — round-trip ferry, beach club entry, basic lunch.

Mid-range (private speedboat): $100-$200 per person — private boat for your group, multiple island stops, drinks included, flexible schedule. Based on group of 8-15.

Premium (luxury yacht): $150-$250 per person — luxury yacht or catamaran, private chef, open bar, snorkeling gear, professional crew. Based on group of 15-30.

Ultra-luxury: $250-$400 per person — mega yacht, full VIP package with chef, DJ, photographer, drone videography, premium spirits. The ultimate island experience.
