Cartagena: Visit 4 islands in a speedboat + plankton!

Cartagena’s most unusual water experience comes at the end of this long day: after sunset, you take a boat into dark water and swim among luminous plankton that glow when disturbed. Before that, you race across the Rosario Islands, stop at Cholón and Playa Tranquila, and watch the sun go down at Playa Blanca.

I like the tour’s four-stop plan and the fact that lunch, a beach chair, life jacket, snack, and return transport are included. I also like the mix of lively beach time and a rare nighttime sea swim. The drawback is organization: the day can involve boat changes, extra charges, crowded beaches, and Spanish-only guiding.

Key points at a glance

• Four island areas in one day: Rosario Islands, Cholón, Playa Tranquila, and Playa Blanca.
• The plankton swim comes after dark: You receive about 20 minutes of explanation before heading out by speedboat.
• A full 12-hour outing: Pickup begins around 6:50 to 7:50 a.m., with return planned around 8 p.m.
• Several costs are extra: Port tax, aquarium entry, snorkeling, photographs, drinks, and some chairs or activities are not included.
• Spanish is the tour language: This matters if you need detailed explanations in English.
• Best for active beach days: The schedule suits you if you can handle speedboats, sun, long hours, and a late return.

Four island stops, one very long day

This is not a quiet island escape. It is a packed day designed to show you several of Cartagena’s most popular coastal stops in one outing.

You leave Cartagena in the morning, travel by bus to the dock, board a speedboat, and spend much of the day moving between beaches and island areas. The reward is variety. You see the Rosario Islands from the water, spend time at Cholón, stop at Playa Tranquila, and finish with sunset at Playa Blanca before the plankton activity.

I would choose this tour if you have only one open day for the islands and want to sample several places. I would not choose it if you want long, quiet hours at one beach. The schedule is tight, and each stop gives you roughly an hour, sometimes a little more.

The tour costs $62 per person before added charges. That is a fair package price for a 12-hour day that includes boat transport, lunch, a snack, the plankton boat, a guide, and a return bus. Still, the final cost rises with the 26,500 COP port tax and optional extras.

Early pickup and the ride to La Bodeguita

Pickup is offered from hotels in Morros, Castillo Grande, Bocagrande, and El Laguito. The listed pickup windows are early: Los Morros from 6:50 to 7:10 a.m., and Bocagrande and El Laguito from 7:30 to 7:50 a.m.

You first ride by bus for about an hour. The day then continues from La Bodeguita dock, with the stated departure time around 8 a.m. Bring your confirmation details, since the plan is sent by WhatsApp the day before. I would also wait in your hotel lobby during the stated window rather than heading out at the last minute.

The dock can be confusing if you are not familiar with Cartagena’s waterfront. Keep the operator’s WhatsApp message handy and ask for help if you cannot find the group. One account of the tour describes being dropped at the port without clear direction, so this is a good place to be proactive.

The boat ride to the islands takes about an hour. A speedboat lets you cover more water than a slow launch, but it also means wind, spray, noise, and a firm ride. Secure your phone and hat. Wear clothing you do not mind getting wet.

Rosario Islands from the water

The Rosario Islands portion begins with a panoramic boat tour and about 30 minutes of guided explanation. The islands are the day’s main setting, with open water, small islands, and coastal views rather than a conventional town visit.

There is an important detail here: the boat does not arrive at a normal beach for swimming in the Rosario Islands. You are out in the sea, and you may be offered optional activities at an additional cost.

The national aquarium costs 40,000 COP per person. Snorkeling is listed at 40,000 COP in one price section and 50,000 COP in the practical notes, so confirm the current amount before paying. If you skip these choices, you may wait on the boat for about an hour.

That waiting time matters. If your goal is to snorkel or see the aquarium, budget for the extra fee. If not, ask where you will sit and how long the stop will last. The Rosario visit is more of a panoramic introduction than a long beach break.

One hour at Cholón

Cholón is the first major beach stop, with about an hour of free time. A shrimp ceviche is included, giving you a light local snack before the later meal.

Cholón is known for a social, party-focused beach atmosphere, and this tour gives you a short taste rather than a full afternoon. The stop can feel lively and crowded, especially when several boats arrive at once. Keep your belongings close and confirm which boat is yours before walking away.

Be careful with drinks and bottled water. One account of the outing describes paying 150,000 COP for three bottles of water at Cholón. That is a useful warning, not just a complaint: bring your own refillable bottle if possible, ask prices before ordering, and do not assume beach prices match Cartagena prices.

The day includes food, but not unlimited drinks. Beers and other purchases are extra. A little cash in Colombian pesos is useful for small payments, but the supplied information does not confirm which vendors accept cards.

Playa Tranquila for lunch and a break

After Cholón, the speedboat continues to Playa Tranquila. The schedule gives you about an hour at the beach, followed by roughly 45 minutes for lunch.

The included lunch helps the $62 price make more sense. You are not paying only for a boat ride and a swim. You also get a meal, a snack, shrimp ceviche, beach time, and the evening plankton excursion.

The beach stop is still short. I would treat Playa Tranquila as a chance to sit, eat, and cool off rather than as your main beach day. The tour includes a beach chair, but the notes also warn that some chairs may cost extra. Ask the guide which chair is included before settling down.

The food receives one of the more favorable comments in the available feedback, with the meal described as good and the staff as friendly. That is worth noting because island excursions often make meals an afterthought. You should still expect a basic included lunch, not a restaurant meal with a broad menu.

Sunset at Playa Blanca, Barú

Playa Blanca on Barú receives the longest evening attention. The schedule allows about an hour for sunset and another 1.5 hours for a guided visit.

This is the part of the day most likely to feel rewarding if you enjoy beach scenery. The sunset gives you a slower pause after the boat transfers and short stops. You can use the beach chair, take photos, and watch the light change before the nighttime activity.

At the same time, Playa Blanca is a popular beach destination, so do not expect solitude. The stop is about seeing one of Cartagena’s best-known beaches at the end of the day, not escaping crowds altogether.

The return plan changes here. After the plankton experience, you return to Cartagena by bus rather than by speedboat. The stated finish is at La Bodeguita dock, though one account describes a driver dropping people in the street instead of directly at the hotel. Confirm your return point and arrange your own final ride if needed.

Swimming with glowing plankton after dark

The plankton activity is the tour’s special feature. Before setting out, you receive about 20 minutes of explanation. You then board a speedboat, put on a life jacket, and take part in a nighttime sea swim.

The glow comes from tiny marine organisms that emit light when the water is disturbed. When you move your hands or body, you may see brief flashes around you. The effect depends on darkness and natural conditions, so it is best approached as a natural event rather than a guaranteed light show.

You can expect the water to be dark and the setting to feel very different from the daytime beach stops. Bring comfortable clothes and be ready to get wet. The tour includes the life jacket, but it does not include plankton photographs. Photos are listed at 35,000 COP.

That extra charge makes sense if you want a record of the swim, since ordinary phone cameras may struggle in dark water. Still, ask to see the price and understand what you receive before agreeing. The swim itself is included, while the photographs are not.

What the price really covers

At $62, this is a value-focused package rather than a private island experience. You receive:

• Hotel pickup from listed northern Cartagena areas
• Bus transport to and from the dock
• Speedboat transport
• Rosario Islands panoramic tour
• One hour at Cholón
• Shrimp ceviche
• Playa Tranquila stop and lunch
• Sunset at Playa Blanca
• Beach chair
• Plankton explanation
• Snack
• Speedboat for the plankton trip
• Life jacket
• Guide
• Nighttime sea swim

Plan for the port tax of 26,500 COP per person. Aquarium entry, snorkeling, drinks, photos, and some chairs or unspecified activities cost extra.

I see the price as good if you want a full day with transport and meals arranged for you. The value is weaker if you dislike add-on selling or prefer to control your own pace. The tour’s 3.1 rating from seven reviews suggests you should book with realistic expectations, especially about organization and communication.

Spanish guiding and group logistics

The live guide speaks Spanish. That is fine if you understand Spanish, but it can make the day harder if you need instructions in English. The tour involves several transfers, optional activities, and different meeting points, so clear communication matters.

I would save the WhatsApp confirmation, take a screenshot of the pickup time, and ask the guide three questions early in the day:

• Which boat should I return to?
• What is included at this stop?
• What costs extra?

The group may be split between boats, and one account describes being moved between boats for snorkeling and the Cholón stop. Boat changes are not unusual on a busy island route, but they can be stressful if instructions are unclear. Keep your belongings in one small waterproof bag and do not leave valuables loose on a seat.

What to bring for the 12-hour outing

Wear comfortable clothes and shoes that can handle a wet boat and beach walking. Sunscreen is essential, and a hat with a secure fit is useful on the speedboat.

I would also bring:

• A refillable water bottle
• A waterproof phone pouch
• A dry change of clothes
• Colombian pesos for extras
• A towel, if you have room
• Your WhatsApp confirmation

The official information lists comfortable shoes, sunscreen, and comfortable clothing. It does not promise towels, so bring one if you want to be dry after the nighttime swim.

The tour is not suitable for pregnant women, babies under one year, or people over 70. The boat ride, long day, heat, and sea swim make those restrictions important rather than minor fine print.

Who should book this tour?

You should book it if you want to see several famous island stops in one day, enjoy a fast boat ride, and consider luminous plankton a must-do experience. It also suits you if you prefer a package with pickup, lunch, guide service, and return transport already arranged.

I would skip it if your priority is peace and quiet, a private boat, strong English-language guidance, or a relaxed beach schedule. I would also think twice if you dislike paying for optional activities at the dock or want every transfer explained in detail.

Should you book it?

Book this tour for variety and the nighttime plankton swim, not for a slow island retreat. The best parts are the four-stop route, the sunset at Playa Blanca, the included lunch, and the chance to see glowing water after dark.

Before paying, accept that the day may be crowded and that organization can vary. Confirm the pickup point, carry water, keep extra cash for the port tax and optional activities, and stay close to your assigned boat. If you can manage those details, this is a practical way to pack Cartagena’s island highlights into one demanding but memorable day.
