Granada - Barcelona - por los montes

Very beautiful tour, mostly hilly and mountainous with few flat stages. Feasible in about 20 days, plus or minus depending on mood and desire to explore the towns. Elevation gain and distances significantly more than indicated if visiting each town center (mostly situated on hills). Routes partly on secondary roads, dirt paths (e.g., Ruta de Don Quijote), but also national highways. Extreme climbing stages for superb views, e.g., in Sierra Cazorla.
