I walked the Norte in May/June of 2013, and really enjoyed it. I chose this because I like the sea and don't like crowds. I too wondered if I would have company along the way, but I read that while their are less pilgrims on this route, the bond between them is stronger. It turned out it was the right decision, and socially I had a great time. I have never laughed so much and enjoyed such good camraderie.
Fairly quickly several of us formed a camino family and would often cook together in the albergs in the evenings, and walk together during the days. They have since become lifelong friends and we have met up in each others countries since then. My favourite moments of the whole camino where the gaiety we shared together.
