Origins
If there's one thing we Cartageneros have always known, it's that the sea is not just a landscape: it's a living force that defines how we live, work, and move. But since the end of the 20th century, that force has become more unpredictable. The most devastating hurricane to directly hit Cartagena in recent history was Hurricane Lenny in 1999, which, with winds of up to 155 km/h and storm surges over three meters high, left the city without electricity for days and erased entire sections of the Avenida del Malecón. Since then, coastal erosion has accelerated alarmingly, and it's not just due to storms: rising sea levels, warming surface waters, and the loss of coral reefs have turned Cartagena into a natural laboratory for climate change in the Caribbean.
By May 2026, the situation is clear: the beaches you saw on Instagram five years ago no longer exist in the same way. Bocagrande has lost more than 15 meters of sand in the last decade, and El Laguito has to be rebuilt with concrete groynes every two years. But it's not all bad news. The city is learning to adapt, and there are places where nature is winning the battle. This article isn't meant to scare you, but to let you know exactly where to go—and where not to—if you want to enjoy the Caribbean without contributing to the problem.

The Coastal Erosion Nobody Tells You About: Bocagrande and El Laguito
Bocagrande is Cartagena's most famous beach tourism neighborhood: tall hotels, seafood restaurants, and a strip of sand that in the 1980s measured over 40 meters wide. Today, at some points, it barely reaches 10 meters at low tide. The culprit isn't just climate change: uncontrolled construction of piers, dredging of the port access channel, and the removal of natural dunes have accelerated the loss. In El Laguito, the situation is even more critical: waves break directly against building walls during October and November, and authorities have had to close sections of the beach to the public due to collapse risk.
What does this mean for the traveler in 2026? That if your plan is to spend the day on the sand of Bocagrande, you'll find a very different experience from the photos of a decade ago. Water quality has also declined: untreated sewage discharges and a lack of renewal currents mean that after a storm, the sea takes on an unattractive greenish-brown color. Even so, hotels continue to operate, and many have installed artificial barriers to protect their private beaches. My honest recommendation: if you want an urban beach, go to the Marbella area or the Club de Pesca, where erosion is less severe and the water is cleaner. But if you can move around, it's better to read the next section.
Practical Tips for Bocagrande and El Laguito
- Location: Bocagrande is the peninsula connecting the historic center to the sea. El Laguito is the southern tip, near the Hilton Hotel.
- Current Status (May 2026): The public beach at Bocagrande has sections closed due to erosion. It is recommended to ask at your hotel before going.
- Nearby Alternative: Marbella Beach (a 10-minute taxi ride from Bocagrande) has better sand and less strong surf.
- Prices: Chairs and umbrellas at Bocagrande cost between $15,000 and $30,000 COP per day. Reference prices from May 2026.
Alternative Beaches Surviving Climate Change: Playa Blanca, Islas del Rosario, and Barú
If you want white sand and crystal-clear water, you have to leave the city. But not all nearby beaches are equally affected. Playa Blanca, on Isla de Barú, is the most famous and also the hardest hit: mass tourism, uncontrolled hotel construction, and erosion have reduced its width by 30% in the last ten years. However, there are areas on the same island that remain intact, such as Playa Tranquila or Playa Suárez, which can only be reached by boat from the Barú dock.
The Islas del Rosario are another case. The Parque Nacional Natural Corales del Rosario is one of the most important reef ecosystems in the Colombian Caribbean, but coral bleaching due to rising water temperatures has been devastating. In 2024, a study by Invemar reported that over 60% of the corals in the area were stressed or dead. However, there is good news: coral restoration projects are working on islands like San Martín de Pajarales and Isla Grande, and responsible tour operators are taking visitors to sites where the reef is recovering.
My favorite beach for 2026 is Playa de los Muertos, on Isla de Tierra Bomba. It's only a 20-minute boat ride from the Bodeguita dock, has white sand, gentle surf, and most importantly, it's managed by a local cooperative that limits the number of visitors per day. There are no large hotels, only fried fish and coconut restaurants. It's the kind of place that makes you understand why it's worth caring about climate change.
Recommended Alternative Beaches for 2026
- Playa de los Muertos (Tierra Bomba): Access by boat from the Bodeguita dock. Trip cost: $20,000 COP per person round trip. Open daily, but better to go on weekdays.
- Playa Tranquila (Barú): Reachable by boat from the Barú dock or by 4x4 vehicle on the unpaved road. Entry fee: $10,000 COP per person.
- Isla Grande (Islas del Rosario): Full-day tours from Cartagena. Look for operators that include snorkeling in coral restoration areas. Prices from $120,000 COP per person.
- Playa Blanca (responsible access): If you decide to go, avoid weekends and look for tours that use biodegradable sunscreen. Entry is free, but parking costs $5,000 COP.
Mangrove and Reef Restoration Projects You Can Visit
One of Cartagena's best-kept secrets is that you can be part of the solution while traveling. The Fundación Bahía, in the La Boquilla neighborhood, has a mangrove restoration program where tourists can plant red mangrove in eroded areas. The experience lasts about three hours, includes a walk through the mangrove, and ends with a fried fish lunch prepared by women from the community. It's not a generic tourist tour: it's an opportunity to understand how mangroves protect the coast from storms and filter pollution.
In the Islas del Rosario, the organization Coralina has set up coral nurseries in the San Martín de Pajarales area. Several snorkel operators offer guided visits where you can see up close how coral fragments are cultivated and transplanted to damaged reefs. The tour costs around $150,000 COP per person and includes snorkel gear, guide, and transportation. The best part: a portion of the money goes directly to the restoration projects.
Another worthwhile project is the recovery of the Ciénaga de la Virgen, a mangrove ecosystem bordering the airport. For years it was a garbage dump and sewage outlet, but since 2021, a joint effort between the city government and the community has managed to clean over 10 kilometers of channels. Today, you can take kayak tours through the mangroves with local guides who explain the history of the place. It's an experience that shows you another side of Cartagena, far from the luxury hotels.
Conservation Projects You Can Visit
- Mangrove Restoration in La Boquilla: Fundación Bahía. 3-hour tours, includes planting and lunch. Price: $80,000 COP per person. It is recommended to book at least 2 days in advance.
- Coral Nurseries in Islas del Rosario: Operators like "Ecoaventura Cartagena" offer the tour. Price: $150,000 COP. Includes snorkel and guide.
- Kayaking in the Ciénaga de la Virgen: Tours from the Ciénaga dock, near the airport. Price: $40,000 COP per person. Open Tuesday to Sunday, 8am-4pm.

Climate Calendar: Best Months to Avoid Storms and Strong Swells
If you want to avoid the weather ruining your trip, you need to know the rhythm of the Caribbean. The official hurricane season runs from June 1 to November 30, but the most dangerous months for Cartagena are September, October, and November. During these months, swells at Bocagrande and El Laguito can reach 2 meters, and southern beaches (Playa Blanca, Islas del Rosario) are often closed to the public for safety. Electrical storms are frequent in the afternoons, and boat tours are regularly canceled.
The best months for the beach are December to April, when the trade winds blow steadily, the sky is clear, and the surf is gentle. May is a transition month: there are still good days, but rains start to appear. June and July are dry but hot, with temperatures exceeding 34°C. August is another transition month, with possible isolated storms.
A curious fact few tourists know: the phenomenon of "mar de leva" (strong swell without a storm) occurs mainly from October to December and affects the northern beaches of the city more, such as La Boquilla and Marbella. If you plan to visit during those months, choose protected beaches like those in the Islas del Rosario or Cartagena's inner bay.
Climate Calendar for Cartagena
- December to April: Best time. Clear skies, gentle surf, temperatures between 26°C and 32°C.
- May: Transition. Sunny days but possible short afternoon rains.
- June to July: Dry and hot. Temperatures up to 34°C. Moderate surf.
- August: Transition. Possible isolated storms.
- September to November: Hurricane season. Strong surf, closed beaches, canceled tours. Avoid if possible.
Current Status
In May 2026, Cartagena is at a turning point. Climate change is no longer a future threat: it is redesigning the beaches, ecosystems, and local economy. But the city is responding. Mangrove and reef restoration projects are yielding results, hotels are investing in sustainability, and more and more travelers are seeking experiences that don't harm the environment. The key is to choose wisely: avoid the most eroded beaches, support responsible operators, and above all, respect the sea that gives us so much.
