In case I am misunderstood, I am not making light of the climbing involved in walking the Norte, especially the first step. Since the Norte hugs the coast for quite a bit, your starting, ending, and highest points will usually be below 600m, often 300m--so not rising to the usual cut off of over 600m for a mountain. But compared to many other routes, there is a lot of up and down, often a very steep up and a pretty steep down, over and over for the whole step. Other routes might have true mountains in them, but they are not one right after another, nor is the incline angle so great. I think many when describing the Norte mention how many hills there are...the workout is a notable feature of the route...more pleasant notable features are the woods, beaches, food, history, and art/architecture
I really enjoyed the norte
