Zipaquirá is a colonial town about 50 km north of Bogotá and one of the most popular day trips from the capital. The main attraction is the Catedral de Sal, an underground cathedral carved entirely out of the walls of an active salt mine. The mine has been worked since pre-Columbian times by the Muisca people, and the current cathedral — the second on the site — was completed in 1995, some 180 metres below the surface. The scale is dramatic: a full-sized nave, side aisles, and an enormous cross carved in relief from the rock face, all illuminated in coloured light.
The town itself has a pleasant colonial centre around the Plaza de los Comuneros, with the Catedral Diocesana on one side and whitewashed arcaded buildings on the others. A tourist train, the Tren de la Sabana, runs from Bogotá on weekends and makes the journey part of the experience.
