★★★★★★★★★★3.7 · 139 reviews · 11 hours · from $69Our pick

Spend 11 hours from Cartagena at Freedom Beach Club in Barú, with a cocktail, lunch, mangrove boat ride, raccoon visit, snorkeling, sunset, and nighttime plankton swim. Spanish-speaking guides lead the day. Staff members Angie and Dequer have received particular praise, though transport and activity timing can vary.

“snorkel di 10 minuti senza boccaglio in una zona dove c'erano davvero pochi pesci, situazione molto confusa, barca per trasferimento al beach club scomoda. chiedono il 15% per pagamenti con carta, cibo non male ma nemmeno ottimo. un po' diverso dalla descrizione del tour. non consigliato”

2.Adventure full day Isla Barú + Mangroves + Snorkel + bioluminescent plankton

★★★★★★★★★★4.0 · 95 reviews · 15 hours (approx.) · from $65

Spend a long day from Cartagena at Barú’s Mambo Beach, with lunch, a short mangrove boat ride, fish viewing with a mask, and a nighttime trip to see bioluminescent plankton. Expect shared transport, changing schedules, local boats, persistent beach vendors, and a return that may come late.

“Great overall except they were late and didn’t make it up. I informed that I had my car. I could have been there at least 2 hours more and it was closer from where I was as well. So I had to pay for parking (a crazy amount with a very rude guy)”

3.Barú Sunset Beach with Bioluminescent Plankton

★★★★★★★★★★3.5 · 32 reviews · 7 hours · from $66

Spend an afternoon at Playa Blanca, use a 30,000 COP dinner voucher at Mambo Beach, watch the sunset, then take a long-tail boat onto warm water glowing with plankton. English and Spanish guides lead this 7-hour trip from Cartagena, though transport and boat comfort can vary.

“The ONLY good thing about this excursion was we had a proper bus on the return trip to Cartagena. We were picked up in a beaten down hot van by a driver that had absolutely consideration for his passengers. He would take off like a rocket, then hit the brakes hard. He was dangerously passing on a road that was rutted and full of holes. Bouncing us so badly that my husband's back was in horrible pain. At Mambo beach the 30,000 cop voucher was a joke! All me and my husband wanted was fries and a water which was only 12,000 cop, and still we had to pay for…”

4.5 Island Boat Tour with Night Bioluminescent Stop

★★★★★★★★★★3.5 · 24 reviews · from $100

Join an English or Spanish speaking guide for a 13-hour speedboat trip from Cartagena through Bocachica, Isla Grande, Cholón, Playa Blanca, and Barú. You get snorkeling gear, lunch credit, a snack, a private-island welcome drink, and a nighttime stop to see glowing plankton. Guide Angel is praised for his energy and care when assigned.

“At first we left late, and we had to take away recreational time at the Fort and add it to Playa Blanca (where they left us for several hours, but I'll explain that later). They called us at 7 am claiming that they would only tolerate a few minutes of delay (a schedule that we respected) and we ended up leaving on the excursion an hour and a half later (maybe more). They asked us for 20,000 more Colombians that WERE NOT SPECIFIED anywhere (understandable, but they should have told us). For the time of the plankton, they left us 3 hours in Playa Blanca (it's beautiful anyway, but I…”

5.Enjoy the beach at Barú: Aviary + bioluminescense plankton

★★★★★★★★★★3.4 · 19 reviews · 11 hours · from $58

Spend a long day from Cartagena visiting Colombia’s National Aviary, swimming near Barú, and relaxing at Freedom Beach Club. Your Spanish-speaking guide handles the transfers, lunch, beach time, sunset, and nighttime plankton trip. The group is limited to 15, but expect music, beach sellers, and extra aviary admission.

“Prywatna plaża” to żart – co 3 minuty podpływają łódki wypchane ludźmi, hałas non stop. O odpoczynku na leżaku można zapomnieć, bo handlarze stoją nad głową i wciskają wszystko jak na bazarze. Wyjazd łódką „na plankton” to jedno wielkie nieporozumienie. Za dużo osób w łódce, która była przeciążona. Kapoków starczyło tylko dla połowy ludzi. Byliśmy zostawieni sami sobie,bez przewodnika, bez opiekuna, bez informacji. Na WhatsAppie nikt nie odbierał, nie odpisywał. Powrót? Chaos totalny. Kilka autobusów, tłum ludzi, zero komunikacji. Nikt nic nie wie, nikt nic nie mówi – zgaduj, z kim i dokąd masz jechać. Strata pieniędzy, strata czasu i masa nerwów. Omijać szerokim łukiem.”

6.National Aviary and Playa Blanca Plankton Full-Day Tour

★★★★★★★★★★3.5 · 17 reviews · 15 hours · from $83

This 15-hour day from Cartagena combines the National Aviary, Barú beaches, Mambo Beach Club, a $30,000 COP lunch voucher, and a night boat trip to see glowing plankton. A bilingual coordinator handles the main transfers, but you should expect a long day, crowded beaches, and some waiting between activities.

“La organizacion del día estuvo muy buena, el aviario espectacular. El almuerzo en Mambo estuvo muy rico, las instalaciones del club bonitas, la playa hermosa, pero muy llena de gente, lo cual hizo la experiencia un poco incomoda. Luego nos trasladaron a otro club de playa para hacer la experiencia del plankton, y estuvimos ahi mucho tiempo sin hacer nada hasta que empezó la charla, entonces opinamos que pudieron habernos dejado en Mambo hasta que de verdad fuera la actividad. El plankton estuvo muy bonito e impresionante, valio la pena, pero el regreso tambien fue como corriendo para poder montarnos en los buses, habia mucha gente regresando al mismo tiempo,…”

7.Barú: Sunset on the beach + bioluminescense plankton

★★★★★★★★★★3.3 · 10 reviews · 11 hours · from $57Best value

Travel from Cartagena to Freedom Beach Club for a welcome cocktail, island lunch, beach time, sunset, and a nighttime plankton swim. This 11-hour Spanish-language tour includes transport, loungers, facilities, and a 10,000-peso cocktail credit. Bring a towel and water shoes, and remember that plankton visibility can vary.

“This was between approximately 7:50am- 9:30pm. The beach we spent the day on was beautiful! It was secluded and so not overrun with tourist. Baru beach is very popular so the beaches can get overcrowded. But it was not explained to us that we would spend the full day on the beach and only go to the plankton in the evening. When we did go to the plankton there was nothing to be seen. It was disappointing for everyone on our boat. The tour is Spanish only and we had people in our group who spoke Spanish and were also confused. Overall maybe not worth a full day, if you…”

“No se realizaron varias actividades por mal clima, y cuando se les pidió reajuste de precio porque no se hizo el recorrido de las islas y el placton, simplemente se negaron. No hubo coctel de bienvenida y estaban desorganizados.”

You’ll get lunch, shrimp ceviche, beach time, sunset, and a nighttime swim with luminous plankton.

“Baru remains the only island appreciated but the rest ... zero .. they come to pick us up at the hotel it's okay they drop us at the port we don't know where to go we ask for help no one calculates us until a whatssap intervention. Then we are crammed into separate boats we are made to change boats again between snorkeling and the island of cholon. The island of cholon we take 3 bottles of water at $ 150,000 super scam the water is disgusting and I'm not talking about the people who come to see us every 2 minutes. Then we take the boat crammed until baru.…”
