Seefestival Radolfzell

Seefestival Radolfzell — Four Days on Lake Constance

When the concert sail is unfurled on the Konstanz harbor peninsula in Radolfzell in early June, and Lake Constance serves as a natural backdrop for the concert experience, the Seefestival is back. From June 3rd to 6th, 2026, the festival presents itself with an explicitly multi-genre program — Reggae meets Brass-Pop, Heavy Metal meets Indie, Hip-Hop meets Folk. With around 2,000 seats at the concert sail, the festival is large enough for supra-regional headliners and small enough for an intimate atmosphere right by the lake. The GREEN-EVENT-BW certification underscores the commitment to sustainable events.

The 2026 Lineup — Four Headliners on Four Days

Wednesday, June 3rd, 2026 — Querbeat

Querbeat from Cologne opens the festival on Wednesday — an 11-member creative collective that merges Brass, Funk, and German Rap into a unique blend. With songs like „Randale“, „Wenn ich tanze“, or „Lichterloh“, they have evolved from Cologne Karneval stages to festival-sized headliners in recent years.

Thursday, June 4th, 2026 — Doro Pesch

Doro Pesch, Germany's Metal Queen, with over 40 years of touring experience. Formerly the frontwoman of Warlock, now a solo artist with a loyal fanbase. A concentrated heavy metal concert on Lake Constance — a rather unusual setting for the German rock icon.

Friday, June 5th, 2026 — Gentleman

Gentleman brought Reggae into German-speaking mainstream consciousness. With songs like „Different Places“, „Soulfood“, or „Mama loves ya“, he is one of the most successful European Reggae artists. A balmy June evening on Lake Constance is a perfect fit for the genre's atmosphere.

Saturday, June 6th, 2026 — LaBrassBanda

LaBrassBanda is the festival finale — the Bavarian Brass-Pop sensation with their unique blend of Ska, Reggae, Techno, and Bavarian folk music. Live, they are one of the most explosive bands on the German festival scene — barefoot, energetic, and full of wit.

Further Acts and Support

In addition to the headliners, the festival features: Folkshilfe (Austrian folk trio pop sensation), Froschenkapelle (local brass band from the Lake Constance region), JA/CK, Knallblech (Brass-Funk), and Stoned Henge. The mix of international stars and regional acts creates a relaxed, diverse festival atmosphere.

Concert Sail and Lakeside Location

The concert sail is the open-air stage on the Lake Constance shore in Radolfzell — a permanent, festive structure right on the water, with a weather-proof roof and a direct view of the lake. The venue is located about 250 meters from Radolfzell train station — perfect for environmentally conscious travel by train. In 2026, access will only be possible from the train station side — a small but important change compared to previous years.

Radolfzell and Western Lake Constance

The town of Radolfzell, with around 32,000 inhabitants, is located on the western shore of Lake Constance in the Konstanz district in Baden-Württemberg. It is one of the oldest towns on the lake, with almost 1,200 years of town history. The Mettnau peninsula offers a special approach to recreation and health. From the main train station, you can reach the concert sail in a five-minute walk. The atmosphere during the festival is a mix of international festival vibes and Swabian-Alemannic coziness.
