The honest thing to say about Cartagena’s beaches is that the best ones are not in Cartagena. The city has sand you can swim from, and it got wider this year, but the water people picture when they book the flight is an hour away by boat or by road, on Barú and in the Rosario Islands. We run beach days here every week, on our own boats and by car, and this is the guide we wish people read before they book: which beach for which kind of day, what changed in the last twelve months, the rules that keep the bill honest, and the two things you have to arrange in advance since March 2026.
The short version
For a swim from your hotel, Bocagrande and Castillogrande, now with a wider main strip after the coastal works. For the cleanest beach inside the city limits, Playa Azul in La Boquilla, the only one in Cartagena with a Blue Flag. For the postcard, Playa Blanca on Barú, by boat with the islands or by road in an hour on a rebuilt highway. For a quieter version of the same coast, Playa Tranquila, which is where we take families. For the full day on the water, the Rosario Islands with a private boat, which is the one that people describe first when they get home. Cholón is a party in a lagoon, not a beach, and worth two hours, not a day.
What changed in the last year
Three things, all recent enough that most guides have not caught up. First, Bocagrande’s beach is physically wider: the coastal protection project of the national disaster agency, the UNGRD, and the city, a 245,443-million-peso program with the UNGRD paying 62 percent, delivered Playa 2 on the first weekend of September 2026, 360 meters long and more than 50 meters wide, about 30 meters more than before, with Playas 3, 4 and 5 already finished and the first phase at 93 percent. Second, Playa Blanca has a pier: until October 2025 boats ran onto the sand and you jumped into the water with your bag over your head; the district built a 300-square-meter pier on 28 pilings for 16 boats, a February 2026 cold front with waves over three meters tore the decking off, and the contractor rebuilt it in aluminum under the works guarantee and reopened it on March 31, 2026, in time for Holy Week. Third, the road to Barú, the Transversal Barú, 37 kilometers that locals called the road of shame, was rehabilitated by the city through Edurbe with the Playetas stretch delivered on December 15, 2025, so everything you have read about the drive being a punishment describes the road before that date.
The beaches, one by one
Bocagrande, El Laguito and Castillogrande. The city beaches, a fifteen-minute walk from the clock tower along the peninsula of hotels. Grey-brown sand, a lot of vendors, warm water, and now a real width of beach on the main strip. They are for a late-afternoon swim from your hotel and a beer in a plastic chair, not for the day, and Castillogrande on the bay side is the calmer of the three. The rule is the vendor rule: say no once, clearly, and pay only for what you ordered.
Playa Azul, La Boquilla. North of the airport, in the fishing village of La Boquilla, the Blas del Teso sector of Playa Azul holds the Blue Flag of the Foundation for Environmental Education, awarded in Colombia through Acodal for water quality, safety, services and environmental management, first won in 2019 and renewed for five consecutive years. It is the answer to “which beach inside Cartagena is actually clean”, a twenty-minute car ride from the Old City, with the mangrove canals of La Boquilla next door for a canoe trip with the fishermen. Fewer vendors, fewer visitors, no hotel towers.
Tierra Bomba and Punta Arena. The island across the mouth of the bay, ten to twenty minutes by launch from Bocagrande or Castillogrande, with the beach clubs of Punta Arena facing the city. The water is better than Bocagrande’s, the sand is the same color, and the point is the short boat ride and a day bed in a beach club rather than the beach itself. Fine for a half day; not the day you came for.
Playa Blanca, Barú. The famous one: a long strip of white sand and turquoise water on the coast of Barú, about an hour from the city by road or by boat. It is inside the Corales del Rosario y de San Bernardo National Natural Park, so it comes with the park’s rules, and it is busy on weekends and holidays because everyone can now drive there. The beach is at its best early, before the boats from the city arrive, and at the ends of the strip rather than the middle. Our private Rosario Islands boat spends its last four hours here under a reserved spot in the shade, with chairs, after the islands, which is the way to see it without the crowd of the midday arrivals.
Playa Tranquila, Barú. Around the coast from Playa Blanca on the same stretch of Barú, inside the same park, and the beach we recommend to families and to anyone who read the Playa Blanca reviews. Shallow, clear water, white sand, palm shade, far fewer people. Our day trip to Playa Tranquila and the aquarium is eight hours with a private guide, hotel pickup, the ninety-minute boat ride out on a shared boat, the Rosario Islands aquarium first, then the afternoon on the beach with a lunch of fish, coconut rice and patacones cooked by the island’s own cooks, included.
The Rosario Islands: Playa Grande, Isla Grande and Cholón. The archipelago is the national park’s heart, about an hour by boat from the city, and its beaches are small, coral-fringed and reached by water. Playa Grande is where we snorkel over living coral; Isla Grande has the island hotels and the mangrove lagoon; Cholón, on the Barú side, is a lagoon of anchored boats, floating bars and loud music, which is either your idea of heaven or the two hours you tolerate before the beach. On our private boat the day is yours: an hour at Playa Grande, two at Cholón if you want them, four at Playa Blanca, and the captain moves when you say so.
The full island day, with the park fee, the insurance, the rules and the hours, is in our Rosario Islands guide.
The rules that save you money, and the two things to arrange in advance
Overcharging is the real risk on these beaches, not crime. In 2025 the city logged 289 complaints of excessive charges to tourists between January and July, 137 of them in July alone, including a bill of 6.5 million pesos for three meals, two cocktails, a hookah and a rented speaker at Playa Blanca; the district’s security agency, Distriseguridad, intervened and the visitors paid the fair rate. The tool that made that possible is worth saving before you go: Titán Chat, the district’s WhatsApp line on +57 304 251 1127, open 24 hours and in several languages, where you can ask for the official price of a chair, a lunch or a boat and report a bill that is wrong while you are still at the table. The rules that make it unnecessary are simple: agree the price of chairs, tents, food and drinks before you sit, ask for a written menu, pay in cash in small notes, and do not accept a massage, a plate of oysters or a “free” photo you did not ask for. And on Playa Blanca do not argue with anyone at a checkpoint who wants to search your bag: a 2016 district decree does restrict bringing food into the protected beach, but in April 2025 the mayor dismantled the informal checkpoints run by vendors and stated that natives, tour operators and community councils are not an authority; only the district’s beach control unit and the police may inspect.
The two things to arrange in advance apply to everything inside the national park, which means Playa Blanca, Playa Tranquila and the islands. Every visitor pays the park’s entrance fee, and since March 1, 2026, every visitor also needs the mandatory accident insurance created by Resolución 273 de 2024, sold by the approved insurers and separate from the entrance fee. On the shared boats from the Muelle de la Bodeguita both are handled at the dock in a queue; on a private tour ask your operator in writing what is included so that nothing is a surprise on the day. Bring reef-safe sunscreen, because the coral you snorkel over is alive, and keep your passport in the hotel safe and a copy with you.
The beach bill is the first item, in order, in our guide to whether Cartagena is safe, which also covers the boats, the swimming zones and the habits that keep the rest of the trip simple.
When the sea cooperates
The beaches are hot all year, so the question is the sea, not the temperature. From December to March the trade winds blow hard along this coast, the walls of the city are pleasant in the afternoon and the crossing to the islands is choppy, sometimes enough for the port authority to hold the boats; a private captain leaves earlier, before the wind rises, which is one reason we do. From April to November the sea is calmer and the water clearer for snorkeling, with afternoon storms from September through November that pass in an hour; our guide to things to do in Cartagena has the month-by-month picture. Weekends, Holy Week and the long weekends Colombia moves to Mondays fill Playa Blanca by eleven; a weekday morning is a different beach.
Which beach day we would book
One day and a real budget: the private Rosario Islands boat, because the day belongs to you and the four hours at Playa Blanca happen at the good end of the strip. One day with children or with a modest budget: Playa Tranquila with the aquarium, because the boat is shared but the guide, the lunch and the entrance are handled and the beach is the calm one. Half a day: Playa Azul in La Boquilla by car, or Tierra Bomba by launch. No day at all: a late swim at Castillogrande and the sunset from the walls, which is a fine Cartagena too.
Questions travelers ask
Which is the best beach in Cartagena?
Inside the city, Playa Azul in La Boquilla, the only Blue Flag beach in Cartagena. For the day trip, Playa Blanca on Barú early in the morning or Playa Tranquila if you want it quieter. For the full day, the Rosario Islands by private boat.
Can you swim at Bocagrande?
Yes. The sand is grey, the vendors are many and the water is warm, and the main strip was widened in 2026 by the coastal protection works. It is a swim from your hotel, not a beach day.
How do you get to Playa Blanca?
By road in about an hour on the rebuilt Transversal Barú, or by boat as part of an islands day, landing at the pier reopened in March 2026. Our private boat arrives after the islands, for the last four hours, when the midday crowd is leaving.
Is Playa Blanca in the Rosario Islands?
No. It is on Barú, the stretch of coast south of the city that is joined to the mainland by a bridge, inside the same national park as the islands. The islands themselves are another hour of water beyond it.
Do I need insurance to visit the Rosario Islands?
Yes, since March 1, 2026, every visitor to the national park needs the mandatory accident insurance, separate from the park entrance fee. On shared boats it is arranged at the dock; on a private tour ask what is included before the day.
What should I do if I am overcharged on a beach in Cartagena?
Do not pay under pressure. Write to Titán Chat, the district’s WhatsApp line on +57 304 251 1127, which is open 24 hours, in several languages, and has already reversed bills of millions of pesos at Playa Blanca. Agreeing prices before you sit down avoids the conversation.
Plan it with us
Our beach days are private, with hotel pickup in the Old City, Getsemaní, Bocagrande, Castillogrande and El Laguito, and a guide who lives here. Write to us on WhatsApp with your dates, or see everything we run on the coast on our Cartagena tours page.
