For two days at the end of May, vineyards scattered across Prague will swing open their gates — many of them sites that remain closed to visitors for most of the year. On May 30 and 31, 2026, residents and tourists alike will have the chance to walk through municipal and private vineyards, taste locally produced wines, and hear the stories behind some of the city’s oldest green spaces. Most vineyards will be open free of charge between 10:00 and 18:00 on both Saturday and Sunday.
