Medellín or Cartagena? Colombia's beach against Colombia's spring

The short version

Cartagena is the beach option: sea level, hot and humid all year, a UNESCO-listed walled city, cruise ships, and the best-known Colombian destination for foreigners. Medellín is the climate-and-city option: spring weather, flat neighborhoods, top hospitals, a metro. They share the visa, the tax line, the peso, and the airline routes, and almost nothing else. Most people who winter in Colombia for years end up living in Medellín and visiting the coast, not the other way round.

Climate

Cartagena averages around 28°C (82°F) with high humidity, day and night, every month; December to April is the drier, breezier season, which makes it the best time to be there, and May to November is wet and still. You will live in air conditioning. Medellín's winter is 75°F days, 62°F nights, dry and sunny, with the windows open. If heat is what you're escaping to, Cartagena; if heat is something you'd rather not manage after 60, Medellín.

Terrain and daily life

Cartagena is flat, which is a genuine advantage, and the old city is walkable if you like cobbles and crowds. Daily life for a foreign visitor centers on Bocagrande's high-rise strip, the old town, and Getsemaní, with tourism everywhere and prices to match. Medellín's Laureles and Envigado are flat too, and they're neighborhoods where you're a resident, not a tourist: bakeries, markets, parks, and prices set for Colombians.

The beach, honestly

Cartagena's own city beaches, at Bocagrande and Marbella, are urban and modest, with dark sand and persistent vendors. The good beaches are the Rosario Islands and Barú, a boat ride or a drive away. If beach is the whole point, Santa Marta and the Tayrona coast, four hours east, have better sand and lower prices. Medellín has no beach; the Caribbean is an hour's flight from either of its airports.

Cost

Cartagena is Colombia's most expensive city for a visitor: furnished apartments in the tourist zones are priced for foreigners and cruise passengers, restaurants in the old town are Miami-priced, and air conditioning adds to every utility bill. Medellín's good neighborhoods cost less for better apartments, and daily life costs a fraction. The peso and exchange-rate caveats are the same in both.

Healthcare

Cartagena has capable private clinics for a city its size. Medellín has several of Latin America's top-ranked hospitals and is where Colombians go for complex care. Sea level also means Cartagena's mosquito-borne illnesses, dengue in particular, are a bigger consideration than in the Medellín valley. For a visitor with a condition to manage, this section is decisive.

Safety

Both cities are covered by the same Level 3 country advisory. Cartagena's visitor crime is mostly tourist-zone hustle: overcharging, aggressive vendors, drink-spiking in the nightlife areas, and occasional theft on the beaches. Medellín's is street theft and the dating-app scheme, covered in the safety article. Neither is a reason not to go; both reward the same short list of habits.

Flights

Both airports take nonstop flights from Miami, Fort Lauderdale, and New York. Cartagena's is inside the city, ten minutes from Bocagrande; Medellín's is 45 minutes away on the plateau. Between the two cities it's an hour's flight, several times a day, which is why the combination works.

The combination that works

Book Medellín by the month, in a flat neighborhood with an elevator, and treat the coast as a trip: a week in Cartagena's old town, a week on the Tayrona coast, a few days on the islands. You get the beach when you want it and spring weather, hospitals, and a real city the rest of the time, at a lower total cost than a Cartagena season. This is what most long-term winter visitors end up doing, and it's what I'd plan for you.

The verdict, by visitor

• Choose Cartagena if

  you want heat, the sea, a postcard old city, and a resort-style winter, and you're happy in air conditioning and tourist prices.

• Choose Medellín if

  you want spring weather, a walkable residential neighborhood, top hospitals, and local prices, and a beach week or two is enough beach.

• Choose Santa Marta over Cartagena if

  beach is the priority but Cartagena's prices and crowds aren't; it's cheaper, quieter, and next to Tayrona.
