Its remarkably difficult to get lost on the Portuguese Camino! My 12 year old daughter and I walked it a couple of years ago, and to keep her interested I suggested she counted the yellow arrows as we went along, and stopped to take a photo every 100 arrows. We got to several hundred very quickly, and were into the thousands by the Spanish border. The good thing about getting lost is you can always find your way again very easily. Fear not, if you have half as good a time as we did you will have a great walk. (My daughter loved it, we are going back for our third camino this spring).
