The sweet fragrance of a guava candy factory, or the scent of tanned hides from a long line of leather shops. The heat of the sun from a cloudless sky, or a cool breeze blowing across desolate hills. The sound of church bells, or a roving band of mariachis singing songs of love and loss. And the beauty of a mountain overlook, or a tranquil plaza in a colonial village. Traveling this part of the TransMexico Norte bikepacking route has served up a feast for the senses - anchored on each end by two of Mexico’s fabled silver cities, which at one time generated most of the wealth in the world.
