We mapped out our route from Colombia to Argentina using Google Earth to make sure to find lots of dirt roads. We can still cycle off if we hear about nice spots but it gives us peace of mind to know that we don’t have to plan where to cycle to the next day…. We carry a GPS (Oregon600) and an IPad on which we loaded our maps and routes. However you’re planning your trip, these maps might come handy, plus some people like to carry around paper maps, as they might provide more detail than what you might be able to download.
