The only difficult parts are in cities, where after several days in nature, hamlets and villages, the pilgrim often becomes a rubbernecking tourist gawking at traffic, interesting buildings, store windows, and people who don't look like ragpickers with a backpack. In town it is very easy to miss a turn or to wander off in the wrong direction-take care. You will also hear stories of those who rise before dawn and rush off and out on the Camino, miss an arrow, and finish the day with an extra 5-10 kilometers. Do know which general direction you should be going and check the direction other people are progressing or look for reassuring signs, arrows, and shells. Many of our Teutonic brethren and indeed the French are intrigued by topography; they may carry maps showing the elevation of every kilometer and can go quite bonkers about unforeseen rises or descents. Maps are fun but not needed.
