My journey on the Camino de Santiago earlier this year began with a single step, but I ended up walking about 500 miles, mostly alone, carrying a 22-pound backpack. The route I took, known as the Camino Francés, began at Saint-Jean-Pied-de-Port, France, on the north side of the Pyrenees Mountains. I then followed the ancient pilgrimage path to Santiago de Compostela, Spain, and finished at the tomb of St. James the Apostle. Sound like fun? For me, it was.
