Celebrate San Isidro
The festival of Madrid’s patron Saint, San Isidro, is one of the best of the year. Officially occurring on May 15, the festivities last over a week, and everyone heads down to the Pradera, which are the festival grounds down by Madrid Río, to eat, drink, shop, picnic and listen to live music. Delicious donuts, called rosquillas, can be found at bakeries throughout the city around these dates. Fireworks occur in the Retiro Park and live music can be heard in squares all over town, so check out the official program for more details.
