Bucaramanga is the capital of Santander department, perched on a broad plateau in the eastern Andes at around 960 metres. The altitude gives it one of Colombia's most reliably pleasant climates — warm but not oppressive, rarely cold — which earned it the nickname "City of Parks." Wide green plazas punctuate the urban grid, and the air carries the smell of guayaba and roasting corn from street vendors. A large student population from several major universities keeps the city energetic and surprisingly cosmopolitan for its size.
The food culture is the thing that stops Colombian travellers in their tracks. Santander is famous throughout the country for hormigas culonas — roasted leafcutter ants that are harvested once a year when the queens swarm. Crunchy and slightly smoky, they are sold in bags at markets and roadside stalls and have been eaten here since pre-Columbian times. Beyond the ants, the regional table runs to hearty cabro al pastor (spit-roasted goat), mute santandereano (a thick offal-and-vegetable stew), and chicharrón fried until it shatters.
The canyon south of the city is the real jaw-dropper. The Chicamocha canyon plunges more than 2,000 metres below the plateau rim, dwarfing most canyons in South America. From the Parque Nacional del Chicamocha on the canyon's edge, a cable car crosses the void; the views across the brown rock walls and the silver thread of the river far below are extraordinary. The canyon town of San Gil, about two hours south, is Colombia's adventure sports capital and a worthwhile base for white-water rafting, paragliding, and caving.
The historic colonial village of Girón, now folded into the metropolitan area but still distinct in character, is the most atmospheric short excursion from the city. Its whitewashed churches, cobbled streets, and overhanging balconies make it feel centuries removed from Bucaramanga's busy commerce. Combine it with lunch by the river and it fills a pleasant half-day.
