This is one of those Cartagena trips where you get your own private boat and choose the stops, not the other way around. I love that the operator supplies snorkeling equipment when you reserve ahead, so you can get into the water without scrambling. My only caution: with a max group size of 15, the boat can feel tight if you have lots of people and you want to move around a lot.

The vibe here is practical and easy. You can plan a route across the Rosario Islands, Tierra Bomba, and up to the north side of Baru Island, and the captain helps with options (without turning it into a sales pitch). If you want a simple day built around beaches and snorkel breaks, this hits the mark.

Key things to know before you go

• You pick the destination area, then the crew recommends specific spots if you want help.
• Snorkeling gear is included, but you need to request it in advance.
• Cooler with ice is provided, so you can bring your own drinks.
• Life jackets and children’s vests are available for everyone aboard.
• The boat has permits and required maritime insurance, plus two engines for power and control.
• You can add activities like the aquarium, but entrance tickets are on you.

1) From the Marina to MAMAJUMA: What the start feels like

Your day begins at the main entrance of the marina in Cartagena. Look for the boat name MAMAJUMA and use that when you check in. It is a straightforward meet-up, which matters because on-water schedules get tight fast.

You are in a private group, and the crew includes a captain plus an assistant. That pair is a big deal for a one-day outing because they handle the practical stuff: fuel, boat operation, and making sure everyone has what they need for swimming and snorkeling.

Also worth noting: the boat is described as fully permitted with the maritime authority, and it carries the insurance required. You are not guessing about whether things are legitimate. It is the kind of detail that makes a day on open water feel less stressful.

2) Where you can sail: Rosario, Tierra Bomba, and north of Baru

This is not a fixed “one route only” trip. You can go to basically any place in the Rosario Islands, Tierra Bomba, or the north of Baru Island. Tell the crew what you want, and they’ll either build the day around that or suggest options.

That flexibility is the whole point of this kind of private day boat. You can choose how the day moves:

• Want classic island beaches and calm swim time? Lean toward Rosario.
• Want a change of scenery and easy beach access? Tierra Bomba and the wider Baru area can fit.
• Want a mix of public beach stops and hotel beach time? You can structure the day that way.

The practical downside of freedom: you still need to decide your priorities. If you don’t care where you land and you just want to hop randomly, the day can feel rushed. If you come with a couple of target beaches in mind, everything feels smoother.

3) The boat setup you’ll actually notice: shade, seats, and comfort

A private boat day lives or dies on comfort, especially when you plan more than one stop. Here, you get several details that make the trip feel built for a day at sea:

• Reclining sun loungers for relaxing between stops
• A fresh water shower (useful after salt and sunscreen)
• Two engines, which helps with handling and confidence when you’re moving around
• A sound system with Bluetooth connection, so you can play your own music without passing around a speaker

Then there’s safety and peace of mind. You get life jackets for all occupants, and there are vests for children. That matters if you have mixed ages, or if some people in your group are not strong swimmers but still want to float and enjoy the water.

One more practical note: the crew provides the big on-boat essentials (captain and assistant), so you’re not doing mental math about fuel, timing, or equipment. You just show up and enjoy.

4) Snorkeling gear and tanks: your water time, your rules

Snorkeling is one of the best ways to make a one-day island trip feel like more than just sunbathing. For this experience, snorkeling equipment is included—but you need to arrange it with previous reservation. Plan ahead and you’ll show up ready.

There is also the option for snorkeling services with tanks, again available with prior reservation. If your group includes people who want longer, more comfortable time underwater, this is the upgrade to consider. If you just want to float, see fish, and enjoy the basics, the included gear is enough for a good day.

Because this is a private outing, you can also control how snorkeling fits into the schedule. You can do a quick swim when the boat stops at your chosen beach, then switch back to lounging. That stop-start rhythm is often the difference between snorkeling feeling like a chore vs. feeling like fun.

5) Beach hopping on Baru: White Beach, Agua Azul, Cholon, and more

Baru Island is where many people come for that mix of public beaches, easy water access, and a slightly more laid-back feel than the mainland.

From the available options, you can aim for beaches like:

• White Beach
• Agua Azul
• Cholon
• and other spots around the island depending on the captain’s recommendations

A key detail for your planning: some beaches and private hotel beaches may require previous reservation. In other words, if you want an organized beach setup, give the crew your preferences ahead of time so you don’t arrive and find you need a quick scramble.

On the plus side, you can also use the islands of Rosario or Baru as your base for meals and downtime. You can eat at a beach setup or at hotels, depending on what is available on the day. For a one-day boat plan, that flexibility keeps hunger from ruining the timeline.

6) If you want marine shows: the aquarium option costs extra

You have an additional activity option tied to the local aquarium: you can visit and see dolphin and shark shows. Entrance to the aquarium is not included, so you’ll need to pay the ticket fee separately.

This is a good add-on if you have kids, or if your group wants a structured break from swimming. It is also a useful rainy-day fallback if weather is rough—but the trip is still a boat day, so I’d treat it as an add-on rather than the main plan.

If you prefer to spend every minute outside in the water, you might skip it and keep the day focused on beaches and snorkel time.

7) Food and drinks: cooler with ice, bring your own, and eat locally

This is one of the easiest parts of the day to get right. The operator provides a cooler with ice so you can bring your own drinks. That saves money and keeps you from turning lunch into an expense marathon.

For food, you have options:

• You can bring food with you.
• You can also eat at beaches or hotels once you arrive on the islands of Rosario or Baru.

One thing to keep straight: beverages are not included. That means you’ll be managing drinks yourself, which is exactly why the cooler is so helpful. Pack what your group likes—water, soft drinks, juice, whatever makes the day comfortable.

A practical tip: bring a little extra for the slow moments. When you’re doing sun, swim, rinse, and reapply sunscreen, appetite tends to pop up later than you expect.

8) What’s included vs not: the value math for a $695 group price

The price is $695 per group, for a private day up to 15 people, and it runs 1 day. On paper, private boat pricing can look high. The value question is simple: are you spreading the cost across enough people to make it reasonable?

With a group, this can become a smart deal because so much is built in:

• Fuel included
• Cooler with ice
• Snorkeling equipment (with prior reservation)
• Captain and assistant

What’s not included:

• beverages
• food
• tickets to attractions (like the aquarium)

So the true cost depends on what you bring and what you want to add. If your group plans to bring drinks, share snacks or a lunch, and keep optional attractions limited, you stay closer to the base price. If you add aquarium tickets and buy meals on the islands, expect the total to rise.

My rule of thumb: this is best when you have a planned group size and you’re comfortable organizing your own food and drinks. If you’re traveling solo or as a couple and you want zero planning effort, the value shifts.

9) Group size reality check: 5 feels easy, 15 can feel tight

One insight that matters: with around 5 people, the boat has space to sit, walk around, and relax. If your group is larger, it can get crowded, especially if everyone wants to move around for photos, lounging, or frequent swim prep.

If you want a day that feels spacious and relaxed, aim more toward a smaller group in the lower to mid range. If you want a party vibe and you don’t mind sharing space, you can absolutely go bigger.

This is the kind of detail that turns expectations into a great day—or into frustration. Plan for how you like to spend your time on a boat.

10) Who this Cartagena private boat day fits best

This experience is a strong match for:

• Friends groups who want to control the itinerary across Rosario and Baru
• Families with mixed ages who want life jackets for everyone and children’s vests
• Snorkel fans who will reserve gear ahead and want multiple beach stops
• Anyone who prefers options over fixed tours, especially when it comes to choosing beaches and lunch spots

It is less ideal if you hate decision-making. Because the day is flexible, you’ll get more out of it if you come ready with at least a couple of beach ideas (even if the crew recommends the rest).

Should you book this Cartagena launch for Rosario and Baru?

I’d book it if you want a private boat day with real flexibility and you’re happy to handle your own drinks and meals. The included snorkeling gear (with prior reservation) plus the cooler with ice makes it easy to build a full day without extra fuss. And the captain-and-assistant setup gives you confidence that the day will run on the water without constant micromanagement.

Skip it or shop around if you want a fully packaged food-and-tickets experience, or if you’re traveling as a very small group and the per-group price doesn’t feel worth it. Also consider your group size: if you’re aiming for maximum space to move, keep numbers lower.

If you want control, comfort, and the freedom to choose where the day goes, this is a solid bet.
