The largest picnic was set by 22,232 people and was organized by Realizar Impact Marketing and Modelo (Portugal), at the Parque da Bela Vista, in Lisbon, Portugal, on 20 June 2009.

Participants from all around Portugal came to attend and set this record. 400 buses were organised to bring all the participants to the park were the record attempt took place. Participants were first counted at the gate, and later on arm bands with numbers were given to every one who was participating to confirm the number of people participating. The record was attempted together with another two records, largest litter bin and loudest applause.
