When Lake Klopeiner See is bathed in a sparkling sea of lights, one of southern Carinthia's most spectacular summer highlights awaits you: Lake in Flames – a two-day festival full of music, culinary delights and magical moments by the water.

On 9th July, the festive atmosphere will be set with promenade magic and an impressive water and light show. Street performers, street theatre and a colourful supporting programme along the promenade will create a summer festival atmosphere around the lake.

On 10th July, the main programme will follow with live music and musical entertainment at several locations, regional delicacies, a farmers' market, a children's programme and a variety of side events. Culinary highlights and musical performances around the lake will make the whole day an experience for all the senses. A free lake shuttle will conveniently connect the event locations.

The highlight of the evening:
At 11 p.m., the spectacular lake fireworks display begins, transforming the night sky above Lake Klopeiner See into an impressive sea of colours. The interplay of music, light and reflections on the water's surface creates goose bump moments and unforgettable memories.
