Things to Do in Colombia in December

December's dry heat makes Cartagena's old city walkable in a way the shoulder-season humidity does not. The colonial streets inside the walled city, stone underfoot, bougainvillea cascading off wrought-iron balconies overhead, the faint bass thump of champeta music leaking from open doorways, are best explored on foot in the early morning before the sun climbs above the roofline around 10 AM. The trick in December is timing: the walled city is pleasant before 9 AM and after 5 PM, but the midday hours turn the stone plazas into radiators. Head to Bazurto Market, the vast, chaotic, non-touristy market where Cartagena feeds itself, the stalls selling ceviche de camarón from styrofoam cups next to women balancing towers of fruit on their heads. The smell alone, overripe mango and raw fish and diesel and frying empanadas, is an education. December's trade winds keep the coastal humidity from becoming oppressive, and the evening breeze off the bay makes the plaza outside the old clock tower one of the best places in Colombia to sit with an agua de coco and watch the city perform itself.

The Valle de Cocora, a forty-minute jeep ride up a winding mountain road from the town of Salento, is where Colombia keeps its most improbable landscape: wax palms, the world's tallest palm species, some topping 60 m (200 ft), rising out of emerald-green cattle pasture with the Andes rolling behind them in every direction. December's dry season means the main loop trail, roughly 12 km (7.5 miles) and four to five hours of moderate hiking, is at its least muddy. You'll still cross a dozen stream bridges and the cloud forest section stays damp, but you're unlikely to spend two hours ankle-deep in trail soup the way you would in October. The air at 2,400 m (7,900 ft) is cool enough, around 18°C (64°F) in the morning, that the hike feels comfortable rather than punishing. Start early. By noon, cloud rolls in and those well-known palm silhouettes disappear into mist. The town of Salento itself, with its painted balconies and Plaza de Bolívar ringed by coffee shops, is worth a full day even without the hike, sit on one of the painted balconies overlooking the valley with a tinto (black coffee, served sweet) and understand why coffee-region Colombians seem perpetually unhurried.

Medellín in December is two cities at once. By day, the weather earns the city's nickname, Ciudad de la Eterna Primavera, city of eternal spring, with clear mornings around 27°C (81°F), a light breeze moving through the valley, and enough warmth to sit outdoors all afternoon. By night, the entire city becomes a light installation. The Alumbrados along the Río Medellín, running from roughly the first week of December through mid-January, stretch for kilometers, arched displays spanning the river, animated projections on the hillsides, neighborhoods competing to outdo each other with homemade displays. The scale is staggering and somehow still feels communal rather than commercial. During daylight hours, Comuna 13, once the most dangerous neighborhood in the western hemisphere, now a global model for urban transformation, is home to open-air escalators built into the hillside, street art murals that serve as a visual history of the neighborhood's painful past and stubborn resilience, and hip-hop dancers performing on the landings between escalator sections. The graffiti tour through Comuna 13 is not a sanitized tourist product. Guides are neighborhood residents who lived through the worst of it, and their stories about what these streets looked like fifteen years ago sit uncomfortably alongside the Instagram-ready murals. That discomfort is the point.

Tayrona's reopening in December, after its annual ecological closure, feels like the jungle exhaling. The trails from the Calabazo entrance to Cabo San Juan wind through dense tropical forest where howler monkeys shake the canopy overhead and the sound shifts from birdsong to surf as you approach the coast. The hike to Cabo San Juan runs roughly 6 km (3.7 miles) one way, crossing bouldered beaches and climbing through root-tangled jungle paths that demand decent footwear and a willingness to sweat, even in December, the coastal humidity sits around 85% and the shade temperature hovers near 30°C (86°F). But the payoff is a crescent beach backed by massive granite boulders and jungle, with hammocks strung between palms and water clear enough to see fish from the shore. December's early dry season means the trails are passable without being a slip hazard, the rivers running through the park are low enough to ford easily, and the afternoon rains that define the wet months have largely stopped. Mind you, the park's popularity has exploded, the December reopening draws crowds, and the camping spots at Cabo San Juan fill by early afternoon. Get there at dawn or stay overnight.

Cali refuses to treat salsa as a tourist show. Here, salsa is the city's bloodstream, how neighbors argue, flirt, mourn, and celebrate. Across the Río Cauca in Juanchito, the salsotecas throb until the equatorial dawn, and couples who have danced together longer than most marriages last cut across the floor with a precision that makes conservatory dancers look robotic. December cranks the dial to eleven. From roughly December 25 through 30, Feria de Cali commandeers every plaza, avenue, and living room: salsa orchestras on open-air stages, the Salsódromo parade surging down the Calle Quinta while rival dance schools flaunt costumes that took months to stitch, and a citywide mood of controlled euphoria powered by aguardiente and cumbia. The heat, steady at 31°C (88°F) and humid, doesn't fight the music. It joins it, turning sweat into currency. If you have ever stepped through a salsa class and wondered what the real thing feels like, December in Cali will erase every classroom count you ever learned. Outside Feria week, the salsotecas still spin every night, and beginner-friendly group classes run every afternoon in studios scattered through the San Antonio neighborhood.

The 740 steps hacked into El Peñón de Guatapé, a 220 m (720 ft) granite monolith punching skyward from the lakeshore, deliver a 360-degree payoff that justifies every drop of sweat. Below, Embalse Peñol-Guatapé spreads in green fingers between forested hills, freckled with weekend houses and speedboats carving white wakes. December's dry skies make this the clearest month. During the wet season, clouds often swallow the summit before noon. The town of Guatapé, about two hours east of Medellín by road, lives inside the zócalos tradition: every building's lower wall flaunts three-dimensional, brightly colored bas-relief panels of farmers, animals, coffee plants, saints, and saints' horses. Walking the streets feels like strolling through a folk-art gallery that someone forgot to close. December sunlight hits those panels in a way overcast months never manage. Arrive early, by 10 AM the Medellín tour buses roll in, and the staircase up El Peñón sprouts a queue. Weekday visits in early December, before the holiday increase, feel almost private.
