The Szentendre Day and Night Open Festival is for music, literature, theatre, gastronomy, and arts fans. And well,  fans of day trips as it's a 40-minute drive from Budapest. In return for the travel time, you will be rewarded with a gorgeous little town sitting on the Danube bank and an array of free cultural events, such as the concert of Mörk, Jazzformers, or a spectacular light projection.
