A whole day to the 5 Rosario Islands with snorkeling and plankton

Experience the Beauty and Adventure of the Rosario Islands in One Day

If you’re visiting Cartagena and craving a full immersion into Colombia’s stunning Caribbean coast, this full-day Rosario Islands tour offers a well-rounded and memorable escape. Starting at Torre del Reloj in the morning, you’ll hop from one picturesque island to another, exploring crystal-clear waters, vibrant coral reefs, and lively local spots. With a price of $100 per person and an 8-hour itinerary, this tour provides a fantastic balance of guided sightseeing, active snorkeling, cultural stops, and relaxing beach time.

What we particularly love about this experience are the variety of stops and the quality of guides, who seem to make the journey engaging and informative. The chance to snorkel in natural coral pools and see bioluminescent plankton at sunset truly stands out.

A Deep Dive into the Rosario Islands Tour Experience

Starting Point and Logistics

The adventure begins early at Torre del Reloj, the iconic clock tower in Cartagena’s historic center. The tour departs at 8:00 am, giving you ample time to soak in the lively atmosphere of this hub of Colombian culture before heading out on the water. The air-conditioned vehicle ensures comfort during the short transfer to the boat, which is a quick but scenic ride across the bay to the islands.

One of the joys of this tour is the small group size—a maximum of 22 travelers—which ensures more personal attention from guides and a more convivial atmosphere. Many reviewers have expressed appreciation for the knowledgeable and humorous guides, who add a layer of local flair to the experience.

The Itinerary: A Day of Contrasts

What makes this tour appealing is its well-thought-out itinerary, combining cultural, historical, and natural experiences. It kicks off with a brief stop at Fuerte de San Fernando de Bocachica, where you’ll get a panoramic view and a quick history lesson about the island’s strategic importance. This is a perfect way to set the scene for the day ahead, especially if you’re into history or just love seeing forts that whisper stories of colonial times.

Next, you’ll visit Isla Grande, which offers two distinctive experiences: a stop at a sunken plane wreck—a hauntingly beautiful relic—and snorkeling in a natural coral pool at San Martin de Pajarales. One review noted, “Moving between islands by boat was amazing and a great chance to see local life,” highlighting how these transitions add to the authentic Caribbean vibe.

Islas de Los Pajarales is a group of small islands where you can choose between entering the oceanarium or snorkeling among colorful corals. Alternatively, if you prefer a more relaxed pace, you can simply lounge on the beach. This flexibility is appreciated by many who might want to skip strenuous activities.

The lively stop at Cholón on Baru, known for its boat-lined sea bars and young tourist scene, adds a touch of local fun. Here, you’ll enjoy a shrimp cocktail—a simple yet delicious taste of local cuisine. It’s a great opportunity to observe the lively Caribbean seaside life.

From there, the tour takes you to Playa Agua Azul, a tranquil beach perfect for a quick swim or sunbathing. The peaceful surroundings provide a nice contrast to Cholón’s energetic vibe.

The highlight of the day is arriving at Playa Blanca on Isla Baru, where you’ll dine on lunch and then prepare for the bioluminescent plankton experience at sunset. The plankton activity is a true bucket-list moment—glowing, shimmering organisms lighting up the dark waters, creating a surreal, almost magical scene. One reviewer described it as “enjoying the day with the plankton,” emphasizing its uniqueness.

Finally, the journey wraps up with another stop at Isla Baru, giving you a last chance to relax or snorkel before returning to Cartagena.

Highlights and Authentic Experiences

Snorkeling in coral pools is one of the most loved aspects of the tour. The natural coral reef in San Martin de Pajarales offers vibrant marine life, often described as lively and colorful. Reviewers mention the use of snorkeling equipment as seamless, allowing even novices to enjoy the underwater world.

The plankton experience during sunset is a natural wonder. Many travelers find it to be magical, with glowing organisms lighting up the dark waters. It’s a rare phenomenon that’s worth the early evening wait.

The guides are consistently praised for their knowledge and humor. Stephen noted, “He was extremely knowledgeable, funny, and added to the fun experience,” which is a common sentiment. Good guides can turn a busy schedule into a lively, informative trip.

The variety of stops—from historic forts to lively beaches—ensures that this isn’t just a beach day but a well-rounded exploration of local culture and natural beauty.

Practical Considerations

While the tour offers great value, it’s worth noting the tight schedule can feel rushed, particularly if you wish to linger longer at any stop. The duration of each stop is relatively short, often around 45 minutes to an hour, which means you’ll need to be comfortable with moving quickly and boarding boats often.

The cost of $100 includes almost everything—transportation, snorkeling gear, lunch, and the plankton activity—making it a convenient all-in-one day trip. However, entrance to the oceanarium is not included, which might be worth considering if that interests you.

The tour is best suited for moderately active travelers—those who are comfortable swimming and walking between stops. A moderate fitness level is recommended, though the pace is generally manageable.

If you enjoy snorkeling, beach relaxation, and cultural sights all in one day, you’ll find this tour offers excellent value. It’s especially suitable for young travelers and groups who enjoy lively atmospheres, as well as those curious about marine life and historical sites.

If your goal is a laid-back, slow-paced beach day, you might find the schedule a bit rushed. Conversely, if you’re eager for adventure and variety, this trip delivers in spades.
