Fodor's Expert Review Tren Medieval
Leaving from Madrid's Chamartín station, this delightful medieval-themed train service runs to Sigüenza mid-April through mid-November. The (otherwise thoroughly modern) train comes populated with minstrels, jugglers, and other entertainers, and it's a great activity for Spanish-speaking children. The ticket price includes round-trip fare, a guided visit to Sigüenza, entry to the main monuments and museums, and discounts at area restaurants.
