Bogotá stands at about 2,640 metres, high enough that many arrivals feel it on the first day, so most itineraries start slowly rather than heading straight up Cerro de Monserrate, whose summit is near 3,150 metres. The wider point is that Colombia's cities sit at very different heights — Medellín at 1,495 metres, Cartagena and Santa Marta at sea level — so both what you pack and the order you visit them in follow from altitude rather than from the season.

Ten to fourteen days is the usual answer for all three, because the legs between them are flights rather than drives. Bogotá to Medellín takes about fifty minutes in the air against eight to nine hours by road; Bogotá to Cartagena is roughly 660 kilometres and an hour and thirty-five minutes flying; Medellín to Cartagena is about an hour and ten. Allow half a day around each flight and the itinerary stops feeling rushed.

Temperature is set by altitude rather than by month, so the cities barely change: Bogotá stays around 8 to 19°C, Medellín around 15 to 28°C, and Cartagena and Santa Marta around 24 to 32°C whenever you arrive. Rain is the variable. The Andean interior has two wetter spells, April to May and October to November, while the Caribbean coast is driest from December to April. December to March is the usual overall window, and it is also the Colombian holiday season, so Cartagena is busier then.

They suit different trips. Cartagena is at sea level and hot at roughly 24 to 32°C, putting the Ciudad Amurallada, Getsemaní, Castillo San Felipe de Barajas and the Islas del Rosario boat trips within reach, with Santa Marta and Tayrona about 230 kilometres along the coastal road, near four hours. Medellín is 1,495 metres up and mild all year, with Comuna 13, Plaza Botero, the Parque Arví cable car and the Guatapé day trip. Coast for beaches and colonial streets, valley for hills and city life.

Flying is the norm here rather than a luxury, because the interior cities are separated by three ranges of the Andes and the roads over them wind and lose time to the weather. Bogotá to Medellín is fifty minutes in the air and eight to nine hours by road; Bogotá to Cartagena is eighteen to twenty hours of driving. The coastal leg is the exception: Cartagena to Santa Marta is about 230 kilometres and four hours, and most people drive it.

Each is a different kind of add-on. Parque Nacional Natural Tayrona is entered from Santa Marta and its beaches are reached on foot, with Cabo San Juan del Guía sheltered while other coves there carry strong rip currents. Ciudad Perdida, the Lost City, is a multi-day trek inland. The Coffee Region around Salento and the Cocora Valley is a separate leg on mountain roads, and San Andrés is an island some 750 kilometres offshore, reachable only by air. All sit well outside dense city coverage.

Start with where you are standing. The passes between the interior cities, the jungle paths in Tayrona, the cable-car ridges above Bogotá and Medellín and anything offshore are places where a signal genuinely thins — terrain, not a fault. If it also fails in a city, reopen the setup guide the plan came with, confirm the Colombia profile is switched on and selected as the mobile data line, and toggle flight mode once. Check the territory list names Colombia, then send support the order reference and handset model.
