A
picnic is an
excursion at which a
meal is eaten outdoors (
al fresco or
en plein air), ideally taking place in a scenic landscape such as a park, beside a lake or with an interesting view and possibly at a public event such as before an open-air theatre performance, and usually in summer. Descriptions of picnics show that the idea of a meal that was jointly contributed and was enjoyed out-of-doors were essential to a picnic from the early 19th century.
