Changes

* You can also go to "terminalito" from where buses go for the short distances, and the ticket will cost you 2000-3000 pesos to the "peaje"

There are buses running from the center of the city to the University area in the south the MIO buses which have their own lanes and bus stops in the center of the road. Just take the bus which goes furthest south (the last stop is called University if I remember right). Take one of these and get off at the last stop. Continue walking south beside the motorway and you will reach a petrol station or just hitchhike anywhere with space for a car to pull in. Its advisable to get off at a peaje and try get a truck as little traffic other than trucks take the long road through mountains to Ipiales.
