Though somewhat isolated, Cuenca makes a good overnight stop if you're traveling between Madrid and Valencia, or even a worthwhile detour between Madrid and Barcelona. The delightful old town is one of the most surreal looking in Spain, built on a sloping, curling finger of rock with precipitous sides that plunge down to the gorges of the Huécar and Júcar rivers. Because the town ran out of room to expand, some medieval
houses dangle right over the abyss and are now a unique architectural attraction: the Casas Colgadas (Hanging Houses). The old town's dramatic setting grants spectacular gorge views, and its cobblestone streets, cathedral, churches, bars, and taverns contrast starkly with the modern town, which sprawls beyond the river gorges.
