There are two Caribe Tour stations in Santiago. One is located on Maimon St and 27 de Febrero near the Jardines Metropolitanos. And at the other end of that same street on the corner of Duarte, is the only Metro Station.
The second station is located over in Las Colinas, way across town, and is also on 27 de Febrero.
Buses leave every hour for the north coast....
