Cartagena is the most photographed city in Colombia and the one where travellers most reliably overpay. Both facts have the same cause: a UNESCO-listed walled centre small enough to walk across in twenty minutes, receiving cruise passengers, weekend visitors from Bogotá and Medellín, and international tourists all at once.
This is what is actually worth your time, in what order, and where the city stops performing.
The walled city, early or late
The Ciudad Amurallada is the reason people come: cobbled streets, ochre and indigo façades, wooden balconies dripping bougainvillea, and a stone wall built to keep out the English. It has been a UNESCO World Heritage Site since 1984, and it is genuinely as good as the photographs.
The mistake is when you walk it. Between roughly 10am and 4pm the old city is hot, humid and full — cruise groups, tour flags, vendors working the plazas. The same streets at 7am or after 6pm are a different city: shutters open, residents out, light that actually flatters the buildings, and a temperature you can think in.
If you have three days, walk the walled city twice at those hours rather than once in the middle of the day. It is not a large area. Repetition costs you nothing.
Getsemaní, and the thing that is happening to it
Getsemaní sits immediately outside the wall and was, until fairly recently, the neighbourhood visitors were warned away from. It is now the part of Cartagena that most travel writing describes as the "real" one: street art on almost every wall, small bars, salsa spilling out of doorways, and Plaza de la Trinidad, where people gather on the church steps in the evening with beers from the corner shop.
It is worth your evenings. It is also gentrifying quickly, in the specific way that turns a neighbourhood people live in into a neighbourhood people visit. Rents have risen, boutique hotels have moved in, and long-term residents have moved out. That is not a reason to avoid it, but it is a reason to spend money in the small places rather than the ones with an English menu on a stand outside.
The beaches are the part nobody tells you
Cartagena's own city beaches are not the Caribbean you are picturing. Bocagrande, the high-rise strip, has grey-brown sand, murky water and persistent vendors. It is a perfectly good place to live and a poor place to swim.
The clear water is offshore. The Islas del Rosario, a coral archipelago about an hour out by boat, are a national park and are what people mean when they say the beaches near Cartagena are beautiful. Playa Blanca, on the Barú peninsula, is the closest genuinely white-sand beach and is now reachable by road as well as boat, which has made it considerably busier than it was.
Two practical notes. Go independently or with a small operator rather than a large party boat, because the difference in the day is enormous. And check what the boat price includes before you are on it: lunch, park entry fee and snorkelling are quoted separately by some operators and bundled by others, which is where most of the arguments happen.
Castillo San Felipe and La Popa
The Castillo San Felipe de Barajas is the largest fortress the Spanish built anywhere in the Americas, begun in the 17th century on a hill overlooking the city, and honeycombed with tunnels. Go early. There is almost no shade on it, and by midday the stone radiates heat.
La Popa, the hilltop monastery above the city, has the widest view in Cartagena. It is a short taxi ride and most people skip it.
Where the city stops performing
Mercado Bazurto is Cartagena's real market: enormous, chaotic, hot, and where the city's restaurants actually buy fish. It is not a tourist attraction and does not pretend to be. Some visitors love it and some find it overwhelming. Go in the morning, go with someone who knows it, and do not go with anything valuable in an open pocket.
The Palenqueras — the women in bright dresses carrying fruit bowls on their heads — are from San Basilio de Palenque, the first free African town in the Americas. They are a genuine piece of Colombian history and they are also, in the old city, working. A photograph is a paid transaction. Agree the price first and there is no problem; assume it is free and there is.
Practical things worth knowing
Weather. Cartagena is hot and humid every single month. The drier, slightly more comfortable stretch runs roughly December to April, which is also the busiest and most expensive. Expect afternoon downpours in the wetter months that clear as quickly as they arrive.
Peak times. Late December through early January, and the week before Easter, are when Colombians travel. Prices roughly double and the old city is at its fullest.
Getting around. The walled city, Getsemaní and the fort are walkable from each other. Beyond that, use a ride app rather than flagging a taxi, because street taxis here are unmetered and the price is whatever you agree before you get in.
Money. Cartagena runs two price levels — one for residents and one for visitors — more openly than most Colombian cities. That is not a scam, it is a tourist economy, but it does mean the first number is rarely the real number.
Why a local actually changes this trip
Almost everything above is stable. What is not stable is which boat operator is good this season, which restaurant in Getsemaní has quietly become a tourist trap, whether Playa Blanca is bearable on the day you were planning to go, and what a fair price is for the thing you are about to buy.
Cartagena is the Colombian city where that gap costs the most money. Browse Local Friends in Cartagena on Roavi and ask someone who lives there before you book anything, or start with the Cartagena city guide for the full picture.
Frequently Asked Questions
What are the best things to do in Cartagena?
Walk the walled Old City early or late in the day, spend an evening in Getsemaní around Plaza de la Trinidad, take a boat to the Rosario Islands for the Caribbean water the city beaches do not have, visit the Castillo San Felipe fortress in the morning, and go up to La Popa for the widest view of the city.Are the beaches in Cartagena good?
Not in the city itself. Bocagrande, the high-rise strip, has grey-brown sand and murky water, and vendors work it constantly. The clear water is offshore: the Rosario Islands are about an hour out by boat and are a national park, and Playa Blanca on the Barú peninsula is the closest white-sand beach, now reachable by road as well as boat and considerably busier for it.How many days do you need in Cartagena?
Three to four. Two covers the walled city and Getsemaní properly, walked at both ends of the day rather than in the midday heat, and one or two more covers a Rosario Islands boat day and the fortress. Add nights if you want to actually rest on the islands rather than day-trip them.When is the best time to visit Cartagena?
It is hot and humid in every month, so the question is really about rain and crowds. The drier, slightly more comfortable stretch runs roughly December to April. That is also peak season: late December to early January and the week before Easter are when Colombians travel, prices roughly double, and the old city is at its fullest.Why is Cartagena so expensive compared with the rest of Colombia?
Because it runs a tourist economy more openly than other Colombian cities. Cruise arrivals, domestic weekend visitors and international tourists all compete for a small walled centre, and there is effectively a resident price and a visitor price for boats, restaurants and taxis. Street taxis are unmetered, so the fare is whatever you agree before getting in.
