German Championships in Ice Swimming
Zollhaus Open
Every year, the Zollhaus Open German Championships bring together athletes and swimming enthusiasts in icy waters. In our beloved Landhotel Altes Zollhaus, a historic hotel with a lake in the middle of the forest, we celebrate the beauty of nature around us.
Sport e sostenibilità
Per noi, i Zollhaus Open non sono solo una competizione, ma anche un’opportunità per promuovere valori importanti come il rispetto per l’ambiente. Ecco cosa facciamo per rendere il nostro evento sostenibile:
- Wooden medals: utilizziamo legno riciclato dal nostro bosco per creare a mano le medaglie per l’evento
- Local food: We collaborate with local producers to offer fresh, zero-kilometre food.
- No trace in nature: We take pride in leaving each place exactly as we find it, leaving nothing in nature.
