Discovering Barú Island: Snorkeling, Mangroves, Sunsets, and Plankton
Looking for a full-day escape from Cartagena that combines natural beauty, adventure, and a touch of magic? This tour to Barú Island offers just that — from navigating mangrove forests and snorkeling in crystal-clear waters to witnessing one of nature’s most mesmerizing spectacles: the bioluminescent plankton at night. For around $48, you’ll spend roughly 11 hours exploring some of Colombia’s most stunning coastal scenery, making it a solid option for travelers craving both relaxation and adventure.
What we particularly like about this experience is how it blends authentic local environments with a well-organized itinerary — if only the logistics ran a little smoother. The mangrove tour and the opportunity to feed raccoons add a charming and unique touch, while the sunset views promise perfect photo moments. The snorkeling activity is brief but offers vibrant fish encounters, and the bioluminescent plankton swim at night is truly special.
A potential drawback for some travelers is the transportation organization, which, according to reviews, can be a bit confusing or disorganized. Some guests found the boat rides a little rough and the overall coordination lacking. That said, if you’re flexible and ready for a day filled with natural wonders, this tour could be a memorable highlight of your Colombian adventure.
This experience suits those who appreciate nature, love snorkeling, and want a taste of Caribbean magic — especially if you’re comfortable with minor logistical quirks and are eager to see Colombia’s vibrant marine life and lush mangroves firsthand.

Exploring the Full Experience

Once you set out from Cartagena, expect a short 45-minute drive followed by a quick boat ride to reach Freedom Beach Club on Barú Island. The initial boat transfer, lasting around five minutes, transports you to a small but charming beach club where you can relax on sun loungers or beach chairs. Here, a welcome cocktail kicks off the day, setting a laid-back Caribbean tone.
One of the first highlights is the mangrove tour, which offers a peaceful escape into lush wetlands. You’ll likely encounter playful raccoons that reside in the area, a delightful surprise for animal lovers. As one reviewer put it, “Alejandro made our day with games and music — a lively guide who added a lot of fun,” highlighting the importance of a knowledgeable and engaging guide.
Following the mangroves, you’ll head into the waters for snorkeling — a brief but colorful session. Expect to see a variety of fish of different colors swimming around coral formations. While some reviews mention the snorkeling as short and not very deep, it’s still a valuable chance to get into the water and see marine life close up. The actual duration may be about 15 minutes, but the experience of floating in clear waters and seeing fish is worth it.
Lunch is served at the beach club and features traditional Caribbean fare like coconut rice, fried fish, and plantains. Guests praise the delicious food and welcoming atmosphere, which makes the day feel even more authentic. A typical meal here is simple but hearty — a perfect way to fuel up for the afternoon.
As the day progresses, you’ll be treated to a spectacular sunset, perfect for photography and soaking in the beauty of the Caribbean coast. The vivid colors of the sky provide a dramatic backdrop for reflection and relaxation.
Once evening falls, the highlight of this tour begins: the bioluminescent plankton swim. It’s an extraordinary experience where the water lights up with tiny glowing organisms as you swim through them. Guests describe this as “magical,” and it’s genuinely one of those moments you’ll never forget. This tour in the Barú lagoon is a chance to witness one of nature’s rare light shows, often described as an otherworldly experience.
Before heading back, there’s time to relax on the beach, soak up the sun, and enjoy the gentle breeze. The return trip involves more boat rides and the same transportation arrangements, which some guests found a bit chaotic but manageable with patience.

Transportation and Logistics

The tour includes round-trip transfers in air-conditioned vehicles from your hotel in the tourist area of Cartagena, plus the boat transfer to the island. While most travelers find these arrangements convenient, reviews highlight some disorganization — including being dropped off at the wrong hotel or waiting at a McDonald’s for the next bus. These issues seem to be minor inconveniences, but they’re worth keeping in mind if punctuality is a priority.
The tour lasts about 11 hours, so it’s quite a long day — plan for an early start and a full day of activity. The guide speaks Spanish, so some basic language skills could enhance your experience, especially during the mangrove tour and the plankton swim.
You are encouraged to bring water shoes for safety during boat rides and snorkeling, along with a towel for after swimming. Food and drinks are not allowed to be brought along, but the tour provides lunch and snacks, making it a good value overall.
Authenticity and Value

While this tour packs many highlights into one day, it’s important to keep expectations balanced. Some guests, like Juan, mentioned issues with coordination, which occasionally led to frustration. However, others praised guides like Alejandro and enjoyed the beautiful scenery and engaging activities.
The price of $48 seems reasonable considering the number of activities, transportation, food, and unique experiences offered. It’s a good investment for those who want to explore multiple aspects of Barú Island — from wildlife and coral reefs to stunning sunsets and glowing plankton.
