FM4 Unlimited am Attersee (Attersee am Attersee, Austria) 2027

FM4 Unlimited am Attersee returns on Saturday 17 July 2027, with the Austrian public radio station FM4 staging its lakeside open air on the shore of the Attersee in Upper Austria. The day splits in two. A warm up runs from 2pm in the Sprinzensteinpark, soundtracked by the FM4 Boombox, and the main event opens at 6pm on the Strandbadparkplatz beside the lido, where the stage faces the water and the programme carries on after dark.

The event has been running for over a decade in various forms, originally as FM4 Unlimited am Wasser, and sits alongside a sister edition the station stages in Steyr. Capacity is modest and the earlier ticket tiers for 2027 had already sold out at the time of writing, with the regular phase listed at 49 euros. Tickets are handled through Weeztix rather than the festival site itself.

The Attersee is the largest lake entirely within Austria and lies about 50 kilometres east of Salzburg, which makes the site an easy day trip from either Salzburg or Linz. Swimming during the afternoon is part of the format, and the venue pages on the official site cover arrival, parking and the awareness team. For anyone who wants to spend a July afternoon in the water before the stage opens, this is a lakeside music festival built around exactly that.
