As Santiago has been a popular pilgrimage site for centuries there are many different routes to the town’s cathedral. The most popular route is called the French Way, which goes over the border from France into Spain. It lasts 790 kilometers (about 500 miles). For the most part, the trail is of average difficulty but it’s still doable for active people that are in good health. There are also some routes that are more strenuous than others so be sure to research more carefully the path you plan on taking before setting out. It’s also a good idea to build up your strength by taking long walks that increase in duration for a while before you leave for your trip.
