Here you can include references to maps that are somewhere on the internet. Two conditions apply: they cannot be protected by copyright, (or you have to make sure that we are allowed to use them), and you have to make sure that it is ok if we call them up from here. If that is a problem, you can also send us the image file and we will upload it to our server.
Check this map for all the main roads in Peru. Please note that there are almost no roads in the Amazon area.
