The Full Experience: A Closer Look at the 5 Island Boat Tour

Enjoy being on the water? Here are other boat experiences we've looked into in Cartagena
Starting out from Cartagena
The tour kicks off at TODOMAR CHL MARINA SAS, a central point where most travelers meet for their adventure. From there, a speedboat whisks you out into the islands—expect around 20 minutes of lively boat rides as you leave the city’s bustling port behind. The boat is typically comfortable enough for a full group, but a couple of reviews mention that the van back can be cramped, especially after a long day.
First stop: Bocachica
Within about 45 minutes, you arrive at Bocachica, a scenic spot where you can snap some photos and enjoy views on the way. It’s a quick visit, primarily for photos and soaking up the coastal atmosphere, but it offers a glimpse into local life and history.
Isla Grande: Snorkeling and Exploration
Next, after a 30-minute boat ride, you land on Isla Grande—the highlight for many. Here, the clear waters and coral reefs are perfect for snorkeling, with about 45 minutes allocated for the activity. Travelers often rave about the coral areas, describing them as vibrant and lively, making it an ideal spot for underwater photography.
You’ll also have some free time for walking, shopping, or relaxing on the beach. The tour includes a visit and shopping opportunities, giving you a chance to pick up souvenirs or simply enjoy the laid-back island vibe.

Here, you’ll have about 50 minutes to explore, take photos, or grab a quick drink. Some travelers say Cholón is perfect for those looking to experience local beach culture, but if you’re after a quiet spot, it might be a bit bustling.
Planning evening activities? Here are other after-dark options we've examined in Cartagena
Playa Blanca on Baru Island: The Big Break
The longest stop — approximately 4 hours and 20 minutes — is at Playa Blanca. Known for its powdery white sand and inviting waters, it’s a popular spot for relaxing, swimming, or having lunch. The tour provides a lunch voucher of 30,000 pesos, which you can use at local eateries; many find this a good value, though some wish they had more time to explore the area fully.
This stop offers a guided tour and free time, so don’t expect a full day of quiet lounging if you want to explore beyond the beach. Several reviews mention that the wait time at Playa Blanca can feel long, and some wished they had known about the extended stay beforehand, so they could bring snacks or plan accordingly.
Barú: Snorkeling and Guided Tour
Back on the boat, a final stop at Barú gives you the chance to snorkel again or simply enjoy the views. The 85-minute visit includes a guided tour and the opportunity to see marine life up close, which many find rewarding.
Evening: The Bioluminescent Plankton
As the day winds down, the tour shifts focus to the nighttime plankton activity. This is often highlighted as the most magical part of the whole trip. The glowing plankton, caused by natural bioluminescence, lights up the dark waters in a way that feels almost otherworldly. It’s a peaceful, awe-inspiring moment that caps off the extensive day perfectly.
Return Journey
After the plankton experience, a final speedboat ride brings you back to Cartagena, arriving at the marina around 13 hours after departure. The journey can be tiring, especially with the long hours and multiple stops, but many find it worth it for the variety and unforgettable sights.
