From any terminal Station and the airport Olaya Herrera there is a access to the city  tren.

Get down tren station 'san Antonio':

Then follow the metro plus line(or get in for 1 station) until you cross 'carrera 43' and then left for a quarter and half you there.

The Taxi/uber drivers will understand you if you will tell which is near to Parque Periodista or "la playa con girardot"
