As soon as people find out I have done the full Camino Francés AND the Camino del Norte they always ask the obvious question: which is better? Well, here are my thoughts.
Like everything else in life, it is all about your personal tastes, the purpose of your Camino, etc.
The French way has more varied terrain, switching every few days. You get the Pyrenees on day one, then the rolling hills of Navarra, blending into the vineyards of La Rioja, eventually you get to the agricultural hills of Burgos, before hitting the plains of the plateau of Palencia and Leon before arriving at the hills of El Bierzo and the ancient Celtic hills of Galicia. The North or Coastal route on the other hand is amazing beach after amazing beach, and amazing forest after amazing forest, oh, and the only flat bits are the beaches, the rest of the time you are going up or down, which makes this route much tougher physically, but extremely rewarding as you are never more than a day or two away from the sea.
Also since this was the predominant trail in the late Middle Ages, the French way has a lot of history and a powerful spiritual charge, every chapel, every church, and cathedral just has this literally awesome, moving presence. By contrast, the Northern trail was abandoned in favor of the Francés as the Moors were driven out of the peninsula so, in fact, you are walking a much newer trail without so much of the spiritual aspect.
Food is probably better on the North route, as you partake from the bounty of the lush, green countryside and the ocean. This does not mean that the French way is bad, it just does not pass-through San Sebastian, arguably the best food per square foot in the world!!
North Coast of Spain is very green. Why? Because it rains a lot! So, if you commit to the North way, make sure you are prepared mentally and physically to deal with rain, sometimes for days… The French way on the other hand tends to be much drier.
Finally, depending on when you are doing it, the French way can become a bit crowded, while the North route has consistently less traffic.
If you are more into exploring cities and towns, both ways offer great stops, San Sebastian, Bilbao and Santander on the North, Pamplona, Logroño, Burgos or León on the French way.
So, in the end it boils down to what you want from your Camino. If you are looking for tradition and spirituality, go with the French way, if you prefer breathtaking views and more of a physical challenge, go North.
