Is Cartagena safe?

Cartagena is manageable solo if you treat it like Medellín's coastal cousin, not like a Caribbean resort. The Centro Histórico inside the 13km of colonial walls feels safe until about 11pm, with Policía de Turismo stationed at Plaza Santo Domingo and near the Puerta del Reloj. Getsemaní, the backpacker neighborhood south of the wall, has gentrified fast since 2018 but still gets rough past Calle de la Sierpe after midnight. You'll smell the shift before you see it. The sweet frying plantain vendors thin out, the music from Plaza de la Trinidad fades, and the streets go dark and narrow. Solo women report feeling comfortable in Getsemaní until about 10pm. After that, a 7,000-peso taxi back to your accommodation is the move.

The specific threat solo travelers face here is scopolamine, locally called burundanga. It is odorless, tasteless, and renders you compliant within minutes. Victims hand over phones, PINs, and cash without resistance. The delivery method is typically a spiked drink offered by a friendly stranger, sometimes a paper held under your nose with a "smell this perfume" approach. This is not rare. The U.S. Embassy in Bogotá logged 50+ reported cases in 2023 across Colombia, with Cartagena and Medellín as the top two cities. Never accept food, drinks, cigarettes, or papers from people you did not arrive with. In bars on Calle del Arsenal, watch your glass. If someone is overly friendly within 30 seconds of meeting you, that is your signal to leave.

Phone snatches happen on motorbikes along Avenida Venezuela and the stretch between Bocagrande and the walled city. The technique is simple. Two riders on a moto, the passenger grabs your phone while you're looking at Google Maps. It happens in 2 seconds. Keep your phone in a zipped pocket when walking main roads. Use it only when you're backed against a wall or inside a shop. Aggressive vendors in the walled city, especially women selling fruit near the Castillo de San Felipe de Barajas, will grab your arm and demand 50,000 pesos for a fruit cup you didn't ask for. A firm "no gracias" while walking works. Do not stop. Do not make eye contact with anyone holding sliced mango near the clock tower.

For solo travelers specifically, the safety calculus improves if you stay in accommodations inside the walled city or in northern Getsemaní near Café Havana. Bocagrande's high-rise hotels along Carrera 1 feel sterile but safe at all hours, with 24-hour security guards and lit beachfront. The trade-off is isolation. You'll meet fewer travelers there. Hostels like Selina Cartagena or Casa del Coliseo in Getsemaní put you in common areas by 8am, and the free walking tours that leave from Plaza de la Trinidad at 10am and 4pm are a reliable first-day social connector. Water taxis to Playa Blanca on Isla Barú (35,000 pesos round trip from the Muelle de la Bodeguita) run group boats where you'll sit shoulder-to-shoulder with other solo visitors. The humidity sits at 87% most evenings. Your clothes will stick. Carry a small towel.

Night transit is the weak link. Cartagena has no metro and no reliable bus system after 9pm. Taxis should be called by app, either InDriver or Didi, never hailed on the street after dark. Street-hail drivers occasionally run fixed-price scams (30,000 pesos for a 9,000-peso ride) or, worse, drive to isolated spots. InDriver shows you the route and the agreed fare before you get in. A ride from Getsemaní to Bocagrande runs 12,000 to 15,000 pesos by app. If you're out past midnight in the walled city, the 24-hour Éxito supermarket on Calle Larga is a well-lit waiting spot with security. The national emergency number is 123. Tourist police respond in English at the Centro Histórico station on Calle Santos de Piedra.
