Hi, my name is Christina. I just came back from Guayaquil 3 days ago through Cajas at 11 AM and the road was ok, and usually when I need to travel after 3 PM I get back to Cuenca through Canar which is much safer but a little longer (1 more hour). If you are in a rush, go through Cajas. However, if you are worried about safety, Canar is the way to go.
