You could look at the Camino de Santiago, walking route. It is a 800km Pilgrimage route through Spain, and finishes at Finisterre with a short extension. The riding is almost entirely non-technical and has plenty of accom en route. Though it is a pilgrimage route it is walked/cycled by many non-religous types as it is a very interesting cultural/scenic journey in it's own right.
