From Portal del Norte there are frequent buses to Zipaquira. They were leaving from the other side of the platform I arrived to. The bus to Zipaquira was 2800 pesos (August 2007) and it took 55 minutes. When the bus stopped near a road crossing and many people went off I asked if it was Zipaquira and it was, and it was also the place for me to go off at as I wanted to visit the salt cathedral.
Going back to Bogota I walked down to the main road and stopped a bus with the sign Bogota. When it passed Portal del Norte it stopped by the side of the road and from there I and the others had to walk over the road on a bridge to the station. At Portal del Norte I looked for a sign saying B74 but couldn?t find it. I asked for the TransMilenio for Museo del Oro (the stop I wanted to go to) and I was told to take number J 72.
