This article recommends three unusual places to visit in Colombia: 1) The Tequendama Falls Museum, a cliffside building originally intended to be a hotel but now abandoned and dedicated to the natural world. 2) Jaime Duque Park, a bizarre theme park near Bogota containing replicas of ancient wonders and a zoo. 3) The Catedral de Sal de Zipaquira, a cathedral carved entirely out of salt underneath the town of Zipaquira that can accommodate up to 10,000 people.
