Did you know that you no longer have to cross at Aguas Verdes? (I agree, that crossing is not for the faint of heart)
But the new crossing option is amazing!
There is a new Centro Binacional de Atencion Fronteriza (actually two of them, one on each side of the border of each country). I've crossed easily and with safety and speed, back and forth here, as have members of my family, en route from Guayaquil to Tumbes. It is open 24 hours all year. The setup is great: Peru and Ecuador have set up the binational border crossing so that all of your migratory document checking is done in one building, for both countries. The immigration officials from Peru and Ecuador sit right next to one another in the immigration building. You finish your "check out" of Peru with one person and then go right next to that person to "check in' to the other country.
This is the nicest border crossing I have experienced in all of my travels. There are restrooms, a restaurant, a place to walk around, and even a Peru tourism representative available at times.
