REVIEW · SNORKELING
5-Island Rosary Tour with Carthagen Snorkeling and Plankton
Islands, snorkeling, and plankton in one day. It is a long, fun loop off Cartagena with panoramic walks on the way to real water time plus snorkeling equipment included. My one real caution is the plankton portion, where the plan can feel tricky if you are not comfortable getting into open water.
This is the kind of trip that moves at cruise-ship speed, with a quick look at a fort, two island stops, and then a longer stretch at Baru for lunch and the plankton moment. I also like that the group stays small, capped at 25 travelers, and you get a bilingual guide to keep everything clear.
For $69 per person, you are paying for a full day of transportation by sports boat, snorkeling gear, a guided experience, and food. Just go in with realistic expectations about timing and comfort, since it can run 12 to 15 hours.

Key things you should know before you go

- Sports-boat day off Cartagena: You meet at Muelle de los Pegasos and spend most of the morning and afternoon on the water.
- Snorkeling is built in early: You get a guided panoramic walk on the Rosario islands with snorkeling time.
- Two private-island style stops: Kokomo and Cholón keep the day feeling like a mix of viewpoints and pampered beach time.
- Baru is the long stop: Lunch is included there, along with the plankton activity.
- Group size stays controlled: Maximum of 25 travelers helps keep the pace organized.
- Food and drinks are part of the schedule: Lunch (chicken, fish, or salad) plus a seafood cocktail at Cholón are included.
A Rosary Islands mini-cruise that stays efficient

This tour is not just about one beach. It is about stitching together different types of moments along the Rosary Islands coast. You start with the waterfront energy of Cartagena, then switch to sports boats, with the day structured as a steady sequence of stops rather than free-form wandering.
What I like most is the balance. You get scenery time, you get guided time, and you still get enough water time to feel like you actually did something. The trip runs roughly 12 to 15 hours, so it is a real day, not a quick half-day snack.
Also, the maximum group size of 25 matters more than it sounds. Smaller groups usually mean less waiting around when boats are loading and when you transition between islands.

Starting in Cartagena: Muelle de los Pegasos and the fort stop

You meet at Muelle de los Pegasos, where the group comes together and you head out on sports boats. This is a simple start, and it sets the tone: you are leaving Cartagena right away, not spending a long time negotiating land transport first.
The next stop is Fuerte de San Fernando de Bocachica, with about 30 minutes there. Expect it to be more than a photo stop. You are getting your bearings along the Boca Chica area and soaking up the historical context before heading deeper into the islands for the fun parts.
Practical tip: wear something you can sweat in and still feel comfortable walking in. The fort part is short, but you may still want comfortable shoes if the ground is uneven.
Islas de Rosario: panoramic walk plus snorkeling setup

The first big island phase is the Islas de Rosario stop. You get roughly an hour for a panoramic walk together with the snorkeling experience. This is where the tour’s “water payoff” begins.
Snorkeling equipment is included, so you do not need to plan your own rental. That alone makes the tour easier to book and easier to execute, especially if you want to travel light. The guide is bilingual, which helps if you have questions about what to do next or where you should be in the water.
What to watch for: snorkeling time can be weather and sea-condition dependent in any coastal area. If you show up with a calm, flexible attitude, you will usually have a better time than someone trying to stick rigidly to a swim plan.
Kokomo Island: your second island hour

After the Rosario portion, you head to Kokomo, another stop around 1 hour. This feels like a reset in the middle of the day. You get a breather between the earlier snorkeling-oriented timing and the longer Baru segment later.
Kokomo is a great place to focus on the “do nothing” moments. Even if you are the type who likes to keep moving, this hour gives you room to chill, enjoy the salt-air pace, and get ready for the next activity.
Bring your best “island day kit” mindset: sunscreen, sunglasses, and something for shade. You will feel it if you skip basics like sun protection during a full-day itinerary.

Baru is the long chapter: lunch plus plankton

The Baru stop is where you spend the most time, with about 6 hours on the plan. This is the stop that pairs lunch and the plankton activity. Lunch is included, and the menu options are chicken, fish, or salad.
Here is what you should know before you commit your energy. One piece of feedback I took seriously is that the plankton experience can feel uncomfortable for people who are not sure about getting into open water. The guide may explain that even non-swimmers can participate, but you are still making a call in a real ocean environment.
So do this:
- Ask the guide to clarify what “safe to enter” means in practice for your situation.
- Only get in if you feel genuinely comfortable with the conditions.
- If you prefer to observe, you should treat that as a valid plan.
Also, plan for comfort issues around food. A common complaint is that lunch can be very cold, even if it tastes good. Fixable? Yes. If you can, bring a light layer you do not mind wearing at lunch time, so the cold food moment does not ruin your mood.
Cholón: 30 to 45 minutes plus a seafood cocktail

Next is Cholón, within the Rosary Islands area. You spend about 30 to 45 minutes here, and you get a seafood cocktail as part of the stop. The total listed time for this section is about 1 hour, so expect a little buffer for boat timing, getting on and off, and settling in.
This is a good stop for a quick win. You get a snack-style included drink and a bit of that island rhythm before you head back toward Cartagena.
One thing I recommend you keep in mind is how island vendors can behave. Some people find the sales energy intense around Cholón and nearby areas like ocean activity venues. If you dislike frequent interruptions, decide in advance how you will handle it. A calm no and moving with the group usually works better than getting pulled into a back-and-forth.
Heading back to Cartagena: the final 5 hours

The last named stop is Cartagena, with about 5 hours allocated. The tour notes that the day is carried out by a sports boat, so you should expect a return by water, and then some time for getting back to the city rhythm.
If you hate long travel days, this is the part to plan for. Think about hydration, a post-snorkel rinse, and what you will wear on the way back. Even if the boat portion ends earlier, the itinerary often includes time to get everyone positioned and returned smoothly.
A small realism check: your day is long. If you go into the return leg hungry or unprepared, you will feel it more than you think.
Price and value: what $69 buys you (and what you still manage)

At $69 per person, this tour can feel like a strong deal because it bundles the expensive parts of the day: boat transport, snorkeling gear, guide time, and included food. You also get multiple named stops, so you are not stuck paying for one beach and calling it a day.
What increases the value is that you do not have to add rentals or extra meals to make it worthwhile. Lunch at Baru and the seafood cocktail at Cholón are included, and you have the equipment for snorkeling already covered.
What can reduce value is comfort mismatches. The plankton portion may involve water entry decisions, and lunch temperature has been an issue for some people. That does not mean the trip is bad, it just means you should pack and plan like the day will be practical first and perfect-second.
Gratuities are not included, so if you love your guide and the pace works for you, you may want to budget a tip. The tour explicitly says tips are voluntary.
Who this tour suits best
This is a good fit if you want a guided, full-day Rosary Islands outing and you like the idea of combining snorkeling with a more unusual stop like plankton. The itinerary works best if you enjoy movement, like changing scenery, and can handle a day that runs 12 to 15 hours.
It is also a decent option if you want structure without renting gear or building your own boat plan. The bilingual guide and included snorkeling equipment make it easier.
It may be less ideal if you:
- Do not like long boat days.
- Are very sensitive to cold food or lack of control over comfort details.
- Feel anxious about water activities in open water, even when instructions suggest it is possible for non-swimmers.
On the flip side, the tour notes that most travelers can participate, and service animals are allowed, so it is designed to be broadly accessible in normal travel terms.
Tips to make the plankton stop and long day feel smoother
Here are the practical moves that can turn this into a win:
- Decide your plankton comfort level early. If you are unsure about water entry, ask questions before anyone heads in. You do not want to guess mid-activity.
- Bring a light layer for lunch time. If the food runs cold for your day, you will still feel okay.
- Use sun protection aggressively. You will be outside for many hours, with boat time between stops.
- Plan for vendor energy. If strong sales talk bothers you, keep your attention on the group and on your next step.
- Keep your phone charged. The day is long, and you might want to communicate if timing feels off.
Also, you can consider booking ahead. This experience is commonly booked about 14 days in advance on average, so waiting too long can reduce your choice of dates.
Should you book the 5-Island Rosary Tour with snorkeling and plankton?
With a 4.6 average rating from 32 reviews, this tour has enough momentum to earn serious consideration. The strongest draw is the mix of snorkeling, multiple islands, and the memorable plankton experience at Baru, plus the included lunch and a seafood cocktail.
I would book it if you want a guided day that gives you more than one “pretty photo” moment. You’ll likely enjoy the flow from Cartagena to the Rosario islands, the short fort stop for context, the Kokomo and Cholón breaks, and the fact that snorkeling equipment is handled for you.
I would think twice if you know you hate open-water activities or if you are the kind of person who needs meals served warm and timed perfectly. The plankton stop is the make-or-break moment, and lunch comfort can be inconsistent.
If your main goal is snorkeling in a structured day, this is a solid value at $69. If your main goal is a relaxed, low-effort beach day, you might want a different style of island tour.
