The short answer
Yes, you can swim in the sea in Cartagena. People do it every day. But the question behind the question is usually "will I want to", and that depends entirely on which stretch of water you're standing in front of. Cartagena is a city, a bay and a string of islands, and the sea behaves differently at each one.
We live on one of those islands, so here's the honest version from out here.
The city beaches: swimmable, not beautiful
The beaches in Bocagrande sit along a working bay, and it shows. Visitor guides to the Cartagena beaches describe grey sand and water the colour of a bay with shipping in it, cloudy rather than clear. It's warm, it's fine to get in, and plenty of people do. What you won't get is the turquoise from the brochure, because the brochure was shot somewhere else.
The practical upside is that it's right there, on foot from your hotel, with no boat and no planning. If you just want to stand in the Caribbean for ten minutes before lunch, it does the job.
Our beach on Tierra Bomba: cleaner water, more of it
Our beach has volcanic sand. It isn't white like the Rosario Islands, and we'd rather say so up front than have you arrive surprised. It's natural, it's clean, and it leads straight out onto open ocean rather than into a sheltered bay.
That's the trade. The water is clearer than the city's because nothing is sitting in front of it, but it's also the open sea, so it has moods. Some days it's glassy. On windy days there's a shore break and getting in and out takes a bit of attention. It's a swim, not a paddling pool, and that's the reason our regulars come here rather than somewhere flatter.
Playa Mamon is the beach just outside our main gate, a short walk from the property, if you want more sand than ours.
Can you snorkel from the beach? No, and here's why
We get asked this constantly and the answer is no. We do have a house reef, but it sits at six metres and the surface water above it is often choppy, so snorkelling it is more frustration than fish. What works instead is a one hour scuba dive, no certification needed for a first try, which puts you down at the reef rather than squinting at it from above.
If flat, shallow, snorkel-friendly water is the whole point of your trip, the Rosario Islands are the honest answer and we'll happily send you out there for the day.
Where to swim, ranked by what you actually want
| You want | Go here | The catch |
|---|---|---|
| Ten minutes in the sea, no effort | Bocagrande, in the city | Grey sand, cloudy water |
| A real swim in open ocean | Our beach on Tierra Bomba | 25 minutes by boat, shore break on windy days |
| Flat turquoise water and snorkelling | Rosario Islands | A longer, rougher boat ride |
| Water you can see the bottom of, with a drink in hand | Our pools, or a cabana plunge pool | It isn't the sea |
Getting out to the cleaner water
Our boat leaves Cartagena from the Muelle de la Bodeguita at 10am, 11:30am and 5pm, and comes back from us at 11am, 4pm and 5:30pm. It takes about 25 minutes and the crossing is usually smooth, noticeably calmer than the infamous Rosario Islands ride. If the tide is very high or the sea is unusually rough we dock in the village instead, about a mile away, and you finish the trip pillion on a motorbike taxi, which most people end up enjoying more than the boat.
The beach club is open to day visitors from 11am to 6pm, so you can come for a swim and lunch and be back in the Walled City for dinner. Do reserve, though. Our boat has a limited number of seats and if you turn up without one it's a long wait for the next.
One last honest note
The sea, like the rest of us, changes with her mood. We can tell you what the water is usually like in September and what it's usually like in January, and we'll still be wrong some mornings. If the conditions matter for your day, message us the day before and we'll tell you what it's doing. See you on the boat.
