CARTAGENA, EXCLUSIVE launch for Rosario and Baru Islands
Cartagena’s best island day is the one you can shape as you go. This private launch lets you choose among the Rosario Islands, Tierra Bomba, and northern Barú, then spend the day swimming, snorkeling, lounging, and stopping for lunch where it suits you. The boat is the MamaJuma, and the captain can suggest places while leaving the final call to your group.
I like the freedom to avoid a fixed route, and I like the practical extras: fuel, ice, life jackets, and a captain with an assistant are included. The main caution is space. Although the boat is priced for up to 15 people, one booking from five people found it comfortable, while more than seven or eight could feel tight if you want room to walk, sit, and sunbathe.
Key points at a glance

- A private route across three island areas: Choose Rosario, Tierra Bomba, or northern Barú instead of following a set group itinerary.
- The MamaJuma has useful day-on-the-water comforts: Two engines, Bluetooth sound, reclining sun loungers, a fresh-water shower, and a cooler with ice.
- Snorkeling gear is included by prior reservation: Tank snorkeling is also available if arranged ahead of time.
- You control your meals: Bring your own food, or eat at a beach, hotel, or private beach that accepts your group.
- The quoted price is per group: The $695 rate covers up to 15 people, but around five to eight is likely a better fit for comfort.
- The service is Spanish-speaking: Communication before the trip is handled through WhatsApp, and the captain and assistant run the boat.
A flexible launch from Cartagena

This is not a sightseeing cruise with a compulsory list of stops. You meet at the main entrance of the marina, give the name MamaJuma, and set off with a private captain and assistant. The boat has the permits and insurance required by the maritime authority, and fuel is included in the price.
The route is the heart of the experience. You can tell the crew where you want to go, or ask for suggestions. Your choices include the Rosario Islands, Tierra Bomba Island, and the north side of Barú. That gives you room to build the day around your group rather than trying to please strangers with different ideas about beaches, snorkeling, lunch, and music.
The exact starting time depends on availability, so check before booking. The activity is valid for one day, but the supplied details do not give a fixed number of hours. Think of this as a full private boating day, with the schedule arranged between your group and the operator.

Choosing between Rosario, Tierra Bomba, and Barú

The islands are not interchangeable, and your choice affects the feel of the day. Rosario is the natural pick if snorkeling and island scenery are high on your list. The operator says you can go to any place in the Rosario Islands, so you can ask the captain for a route suited to your interests.
Tierra Bomba is closer to Cartagena and can work well if your group wants time on the water without committing to a wider island route. The information provided does not promise a particular beach or attraction there, so ask what is available on your date before setting the route.
Northern Barú gives you access to several well-known beach areas. Public options include White Beach, Agua Azul, and Cholón. These names cover very different kinds of stops, so it is wise to ask about the day’s plan and any fees or reservations before leaving the marina.
The private format is useful here. You can say that you want more swimming and less time at a beach club, or the other way around. A verified booking from a group of five described the captain as kind and generous with suggestions, while still giving the group full control. The captain even called different places to check on specific beach and lunch requests. That kind of help matters when a beach or hotel requires a reservation.
What the MamaJuma gives you on the water

The boat is set up for a long day rather than a quick transfer. It has two engines, reclining sun loungers, and a sound system that connects through Bluetooth. You can bring your own playlist, though the quality of a day at sea still depends more on your group than on the speakers.
A fresh-water shower is a useful touch after saltwater swimming. Life jackets are available for every occupant, with child-sized vests available as well. Those details are especially important if your party includes children or people who are not strong swimmers.
The cooler with ice is included, but drinks are not. Bring what you want to drink, and remember that food is also your responsibility unless you arrange to eat at a beach or hotel. Since you can bring your own meals, the boat can be a good value for a group that prefers a simple picnic over paying beach-club prices.
The boat is described as having room to sit, move around, and tan, but the practical limit is lower than the official maximum. A group of five had comfortable space. The same booking advised against more than seven or eight people if you want to move freely. Fifteen people may fit within the stated capacity, but you should expect a much more crowded boat at that size.
Snorkeling in Rosario and beyond

Snorkeling equipment is included when you reserve it in advance. That qualification is easy to miss, so make the request before your day on the water. The operator also offers snorkeling with tanks by prior reservation, which gives you another option if basic mask-and-snorkel time is not enough.
The supplied information does not specify exact reefs, water conditions, or how long the snorkeling stops last. For that reason, ask the captain what sites are suitable on your date and how the weather may affect the route. You can then decide how much of the day should go toward snorkeling and how much toward beaches.
Life jackets are available for all occupants, and children’s vests can be requested. Even with that equipment, keep a close eye on children in the water. The boat’s flexibility means you can spend more or less time swimming, but it does not mean every stop has the same conditions.
If snorkeling is your main reason for booking, reserve the gear and ask about the tank service at the same time. If your group has mixed interests, the private boat helps because some people can stay on board, use the loungers, or listen to music while others snorkel.

Beaches, hotels, and lunch choices

The day can include public beaches on Barú, private beaches, or hotel stops. Some private places require a previous reservation, so do not assume you can simply arrive and use every facility. Ask the operator to check your preferred stop before you commit to it.
White Beach, Agua Azul, and Cholón are among the public options named for Barú. The activity also allows visits to hotels and private beaches in Rosario or Barú. Each choice brings a tradeoff. Public beaches offer a more direct beach day, while a hotel or private beach may provide a more organized setting but can involve reservations or additional charges.
You can bring your own food, which is one of the clearest ways to control costs. You can also eat at a beach or hotel in the Rosario or Barú islands. Food and beverages are not included, and the listing does not provide meal prices, so check the cost before ordering.
I would make the lunch decision early. Tell the captain whether you want to pack food, buy lunch at a stop, or look for a hotel or beach restaurant. The captain’s ability to call around is valuable here, especially if your group has a specific request or needs a confirmed reservation.
The aquarium option, with an extra ticket

The route can include the aquarium, where you can see dolphin and shark shows. The entrance fee is not included, so budget for that separately. The details provided do not state the ticket price or show schedule, so ask for current information before choosing this stop.
The aquarium makes sense for a group with children or anyone who wants a structured attraction in addition to swimming. It may be less appealing if your main goal is a quiet day on the boat and at the beaches. Because the launch is private, you can decide if the stop earns its place in the day.
Do not treat the aquarium as an automatic part of the charter. You must request it, and you must pay admission. A quick check with the operator will help you understand how it fits with your chosen beaches and snorkeling time.
What the $695 group price really means

The price is $695 for a private group of up to 15 people. Fuel, the cooler with ice, snorkeling equipment when reserved ahead, the captain, and the assistant are included. That is a strong value for a group that would otherwise need several smaller boats or a standard shared excursion.
At five people, the cost works out to $139 per person. At eight, it is about $87 per person. At 15, it is about $46 per person. Those figures make the charter more attractive as your group grows, but the comfort advice matters: the boat may be officially sized for 15 without feeling spacious for 15.
You still need to pay for drinks, food, and attraction tickets. Private beach or hotel charges may also apply, though the supplied information does not state exact amounts. Add those costs before comparing this with a shared boat trip.
The value is strongest for a group that wants control. You are paying not only for transport, but also for the ability to choose the island area, adjust the beach stops, bring your own provisions, and keep the day private. If you are traveling alone or as a pair, the group rate is harder to justify.
Communication, meeting point, and booking details
The meeting point is the main entrance of the marina. Tell the staff that you are looking for the boat MamaJuma. Confirm the marina details and meeting time with the operator before the day, since the supplied information gives the location but not a fixed departure hour.
The driver and crew speak Spanish. Communication through WhatsApp is available, and one booking described the pre-trip process as smooth and clear. If you do not speak Spanish, send your route preferences, food plans, snorkeling request, and any reservation needs in writing before the trip.
You can reserve now and pay later, which helps if your Cartagena schedule is still changing. Free cancellation is available up to 24 hours in advance for a full refund. The experience is a private group activity, and some content may be presented in its original language.
The provider is BUBARU SAS, also identified as BUZOS DE BARU. The boat carries the permits and insurance required by the maritime authority. That is a useful practical check for a private charter, especially when you are arranging a full day away from Cartagena.
Who will enjoy this private island day

I would recommend this launch to families, couples traveling with friends, and groups that care more about flexibility than a fixed sightseeing script. It is particularly well suited to people who want to choose between Rosario, Tierra Bomba, and Barú, or who already have a beach or lunch stop in mind.
It also suits groups with mixed priorities. Some people can snorkel while others lounge, swim, or enjoy the Bluetooth sound system. Parents can request child-sized life vests, and groups can bring food and drinks rather than relying entirely on beach restaurants.
I would be more cautious if your party has 10 to 15 people and wants an open, spacious boat. The official capacity allows up to 15, but the practical comfort advice points to seven or eight for easy movement. A very large group should ask for exact boat dimensions and seating arrangements before paying.
This is also not the best fit if you want a guided tour in English or another language. The stated crew language is Spanish. Nor is it a fully all-inclusive beach package, since food, beverages, attraction tickets, and possible private-beach charges are separate.
Should you book the MamaJuma?
Book it if your group wants a private boat, a flexible route, and the freedom to build the day around snorkeling and beaches. The captain’s willingness to offer ideas, call beach and lunch spots, and let you make the final choices is the strongest part of the experience.
Before booking, settle three things: your preferred island area, your group size, and whether you need snorkeling gear, tank service, an aquarium visit, or a private beach reservation. For five to eight people, the $695 group price offers a comfortable balance of privacy, space, and control.
I would skip it if you are a very small party focused on keeping costs low, or if you want a fixed tour with meals and attraction tickets included. For everyone else, especially a group that has been frustrated by rigid boat itineraries, this is a practical way to make Cartagena’s island day your own.
