Windmills of La Mancha - You can't pass through La Mancha without a detour to visit the windmills. The best spot is Campo de Criptana (near Alcazar de San Juan). Tour the inside of a windmill, named Infanto, where kids can see the gears, wheels and grinding stones up close. The first Sunday of each month, the restored windmill Sardinero, grinds flour. Other mills have been turned into museums - in the windmill Garcilaso Inca, there's a Museum of Farming with traditional tools.
