Introduction: Beyond the Postcards
If you are reading this, you have probably already gotten tired of the lines at the Castillo de San Felipe or the street vendors at Plaza de los Coches. San Diego, that neighborhood that looks like a movie set, holds secrets that even the tour guides don't know well. Here, among cobblestone streets and flowered balconies, there are plazas that don't appear on official maps, patios that only the cats know, and rooftops where the Caribbean looks different. In May 2026, when the sun is strong and tourists crowd the Historic Center, these alternative routes will save your trip.
I grew up in Cartagena and I swear that San Diego has a different rhythm. It's not the noise of the Cathedral, but the silence of an alley at 5 in the afternoon. Here I'm going to tell you how to find those hidden plazas, those corners that seem designed for a photo without people or for a stolen kiss. And look: this is not a generic guide of "instagrammable places." It is a map of what is really worth it when you want to escape the noise.

1. Plaza de los Coches (but seen from inside: the church patio)
Everyone knows Plaza de los Coches, the one with the palenqueras and the wooden horses. But almost no one knows that the real gem is inside. I don't mean the Portal de los Dulces, but the interior patio of the Iglesia de San Diego, which is right next door. This patio is an oasis of silence that contrasts with the bustle outside. The palm trees, the wooden benches, and the smell of incense transport you to another era.
To enter, you have to walk to the church facade (Calle de la Iglesia, corner with Calle del Pozo). It's not an obvious entrance: look for a side door of dark wood, almost always ajar. Inside, the floor of antique tiles and the stone columns give you a unique perspective of the plaza. It is the perfect place for a photo without the crowd in the background, especially between 7 and 8 in the morning, when the light comes in softly.
Fun fact: This patio was originally a cemetery during the colonial era, and you can still see some tombstones embedded in the walls. Locals say it is one of the coolest places in the neighborhood, ideal for sitting down to read or just breathe.
2. El Callejón del Pozo (secret photo at sunset)
If there is a place that defines the spirit of San Diego, it is El Callejón del Pozo. It is not in any major tourist guide, but local photographers know it well. It is a narrow passage that connects Calle del Pozo with Calle de la Mantilla, and its name comes from a water well that existed there in the 18th century. Today, what makes it special is the sunset light.
Between 4:30 and 5:30 in the afternoon, the sun filters through the wooden balconies and creates an effect of golden rays that illuminate the purple bougainvillea hanging from the walls. It is a spectacle that lasts only 20 minutes, but it gives you a photo that looks like it's from a magazine. Bring a wide-angle lens or just your cell phone in portrait mode; the contrast between the shadows and the light is brutal.
To get there, walk from Plaza de San Diego towards Calle del Pozo. You will see a stone arch with a small plaque that says "Callejón del Pozo." Don't be fooled by the size: inside there is a mural by a local artist who painted a giant fish, a tribute to the sea that surrounds the city. It is a spot that almost no one visits, so you will have the place to yourself.
Local tip: If you come with your partner, sit on the stone bench at the end of the alley. It is the most romantic corner of the neighborhood, and the neighbors call it "the lovers' bench."
3. The forgotten little plaza of the San Diego market (no tourists)
When people talk about the Mercado de San Diego, they think of the big building on Calle de la Mantilla, full of crafts and juices. But two blocks away, hidden between Calles de la Cruz and la Amargura, there is a little plaza that seems frozen in time. It has no official name on the maps, but the neighbors call it "la placita de las abuelas" (the grandmothers' little plaza).
It is a small space, about 30 square meters, surrounded by colonial houses painted yellow and blue. In the center there is a stone fountain that no longer sprays water, but serves as a meeting point for the neighborhood cats. The best thing about this place is that there are no vendors, no loud music, just the sound of pigeons and the conversations of neighbors who bring chairs out to the street.
To find it, walk along Calle de la Cruz to # 38-12. There you will see a brick arch that leads to a dead-end alley. At the end, the little plaza awaits you. It is the ideal spot for an impromptu picnic: buy a couple of empanadas on the corner (at Doña Rita's store, open from 8am to 6pm) and sit on the steps of the fountain.
Historical fact: This little plaza was the patio of an old slave house in the 17th century, and it is said that you can still hear murmurs of the stories that were lived there. Local guides rarely mention it, but it is a treasure for those seeking the authentic Cartagena.
4. Hidden rooftop of a café with a view of the rooftops
San Diego has several rooftops, but most are in expensive hotels or touristy restaurants. There is one, however, that is a well-kept secret: the one at Café de la Plazuela, a small place on Calle de la Mantilla, right next to the Iglesia de San Diego. This café has no big sign, just a green wooden door and a handwritten sign that says "Café de la Abuela."
Inside, the café is cozy, with wooden tables and a counter where they prepare tinto (black coffee) with panela (unrefined cane sugar). But what matters is upstairs: climb the spiral staircase at the back and you will reach a terrace with a view of the clay tile rooftops of the neighborhood. From there you see the domes of the Cathedral, the palm trees of Parque Centenario, and in the distance, the Caribbean Sea. It is a place known only to locals and some travelers who take the time to explore.
The café is open Monday to Saturday, from 9am to 7pm. Order a coffee with coconut milk (a house specialty, for $12,000 COP) and sit in the hammock that hangs on the terrace. It is the best place to watch the sunset without paying the inflated prices of the trendy rooftops. And if you are lucky, the owner, Don Carlos, will tell you stories of when the neighborhood was just fishermen and mangroves.
Photo tip: The light at 5pm is perfect for capturing the rooftops with an orange tone. Use a small tripod if you want long exposures, but with a modern cell phone you can also get good results.
5. Community cat shelter on Calle de la Mantilla
If you are an animal lover, this place will steal your heart. On Calle de la Mantilla, among the colonial houses, there is an improvised shelter for community cats that the neighbors have organized since 2019. It is not an official or touristy place, but a space where the stray cats of San Diego find food, water, and affection. It is at # 42-18, in an always-open wooden door that leads to a small interior patio.
About 15 cats of all colors live there: black, orange, tabby. The neighbors leave bowls of food and old blankets, and tourists who discover it often donate food or just pet them. It is a corner of peace in the midst of the tourist chaos, and a reminder that Cartagena is not just parties and walls. The cats are tame, but some are shy; approach slowly and don't scare them.
To get there, walk along Calle de la Mantilla from Plaza San Diego. You will see a cream-colored facade with a small sign that says "Refugio Felino San Diego." There is no fixed schedule, but the cats are usually most active between 7am and 9am, when the neighbors feed them. If you want to help, bring a bag of cat food or just sit on the wooden bench and enjoy the company.
Fun fact: The cats have names given by the locals: there is one they call "Mandinga" because it is black and meows loudly, and another "Costeño" because it is always asleep. The neighbors organize a collection each month to maintain the shelter, and sometimes they hold adoption events.
How to get there and transportation
San Diego is in the heart of the Historic Center of Cartagena, a 15-minute walk from the Torre del Reloj. If you come from Bocagrande, you can take a city bus that says "Centro" (costs $2,800 COP) and get off at Avenida Santander, then walk 10 minutes. From Getsemaní, it is only 5 blocks crossing the Puente Román.
For the route of the hidden plazas, the best option is to walk. The streets are narrow and cobblestone, and a car will only get in your way. Wear comfortable shoes, because you will be going up and down stairs, and the sun in Cartagena is unforgiving. If you prefer not to walk so much, you can rent a bicycle on Calle del Sargento Mayor (from $15,000 COP per hour) or a horse-drawn carriage, but these are more expensive and don't fit into the small alleys.
If you come by taxi from the airport, negotiate the fare before getting in: it should cost between $20,000 and $30,000 COP to San Diego. Don't use Uber, which doesn't work well here; better to hail a taxi on the street or use the app "Taxi Cartagena."
Local tips
- Key times: The hidden plazas are best enjoyed early (7am-9am) or at sunset (4pm-6pm). At midday the sun is unbearable and the places fill up with lost tourists.
- Water and hat: Bring a reusable water bottle (there are several refill points in the neighborhood, like at Café de la Plazuela) and a wide-brimmed hat. The humid heat of May 2026 can be exhausting.
- Cash: Many of these places don't have a card machine. Bring small bills ($5,000, $10,000 COP) to buy empanadas, juices, or donations for the cat shelter.
- Respect for neighbors: These plazas and alleys are homes for local families. Don't make excessive noise, don't enter private property, and ask permission before taking photos of people.
- Connectivity: WiFi in the neighborhood is spotty. Download an offline Google Maps map before you go out, or buy a local SIM at the store on Calle de la Cruz (from $10,000 COP).
- Safety: San Diego is safe during the day, but at night avoid lonely alleys, especially after 9pm. El Callejón del Pozo and the forgotten little plaza are well-lit, but be careful.
Frequently asked questions
Are these hidden plazas free?
Yes, all are public and free to access. The rooftop café charges for drinks, but you can go up to the terrace alone without buying anything if you ask politely. The cat shelter accepts voluntary donations, but it is not mandatory.
How long does it take to do the whole route?
If you do the complete route on foot, taking photos and resting at each place, calculate between 2 and 3 hours. If you want to go more relaxed, you can split it over two days: one morning for the plazas and one afternoon for the rooftop and the shelter.
Are there public restrooms in these places?
There are no public restrooms in the plazas or alleys. Café de la Plazuela has a restroom for customers (with a minimum purchase of $10,000 COP). You can also use the restrooms at the "Mall Centro" shopping center on Calle de la Mantilla, a 5-minute walk away, which cost $2,000 COP.
Can I bring my children?
Yes, especially to the forgotten little plaza and the cat shelter, which are quiet and safe spaces for children. El Callejón del Pozo is narrow, but children can enjoy the bougainvillea and the mural. However, supervise the little ones on the stairs of the café's rooftop.
What is the best time of year to visit San Diego?
The dry season, from December to March, is ideal because it doesn't rain and the weather is cooler. But May 2026 is also a good time, with fewer tourists and lower accommodation prices. However, bring an umbrella just in case, because the rains are unpredictable.
