Make sure you have enough gas in the tank, because Segovia is well worth a detour. Located 40 miles from Martiherrero, it offers some fantastic attractions, such as Segovia Aqueduct and Alcazar of Segovia. Salamanca, 50 miles away, is another road-trip destination that’s worth the journey. Visit San Esteban Convent and New Cathedral of Salamanca, two top-notch attractions in the area.
