If your trip to Sepulveda is all sorted out but your itinerary is a little on the empty side, let us give you a helping hand.Stop by Santuario de Nuestra Señora de la Peña. It's one attraction you'll find on most visitors' to-do lists. If you still have space on that travel itinerary, Museo Lope Tablada de Diego and Museo de los Fueros will keep you busy too.
