The ancient university town of Sigüenza dates back to Roman, Visigothic, and Moorish times, and still has splendid architecture and one of the most beautifully preserved cathedrals in Castile. It’s one of the rare Spanish towns that are not surrounded by modern development and sprawl. If you’re coming from Madrid via the A2, the approach is breathtaking: you pass through hills and ravines before reaching Sigüenza,
surrounded by vast agricultural plains. Sigüenza is an ideal base for exploring the countryside by bike. Spain's famous Ruta Don Quixote, a system of hiking and cycling paths named for Cervantes's literary hero, passes through Sigüenza and nearby villages. The tourist office can direct you to Bicicletas del Olmo, which offers bike rentals and trail maps.
