Summer is a season of celebration in Poland. Students festivals occur at the beginning of summer, and the middle of the season is marked by the excitement of Wianki, the annual solstice party. All across Poland, destination cities welcome visitors with their own calendars of events that include food fests, musical concerts, theater performances, and open-air entertainment. In addition, summer activities include carriage rides through historic city centers, picnics in parks and gardens, castle adventures, and countryside excursions.
