A unique evening by one of Switzerland’s most beautiful mountain lakes The Eis-Schwimmer invite you to an exclusive summer party at the legendary Blausee in the Bernese Oberland. Turquoise-blue, crystal-clear water, surrounded by woods and mountains – and a community that loves the cold and radiates warmth. Look forward to a late summer evening full of fresh inspiration, genuine connections and a relaxed atmosphere amongst like-minded people – accompanied by two extraordinary individuals who will guide you to your own inner strength.

Exclusive swim in the Blausee
The Blausee is one of the most magical places in Switzerland. On this evening, it’s all ours – crystal-clear water, a private atmosphere and an experience you won’t find anywhere else.

Deniz Kayadelen – From taking the plunge into cold water to inner freedom
Deniz is a six-time world champion in ice swimming, a Guinness World Record holder (highest altitude ice swimming record, Nepal 2024) and a Triple Crown open-water swimmer. As a bestselling author, TEDx speaker and business psychologist, she combines scientific depth with real-life experience.

In her workshop, she shares the essence of her PeakFlow Method™️: How consciously stepping out of your comfort zone – for example, taking the plunge into cold water – enables mental clarity, emotional resilience and deep inner freedom. You’ll learn how cold can become your teacher and how to apply this insight to your everyday life.

Andreas Lanz – Breathing, Letting Go, Presence
As a Wim Hof-certified trainer and personal coach, Andreas introduces you to the power of breathing. You’ll discover how to use your breath to prepare your body for the cold water – and how this practice can also give you more energy, focus and calm in your everyday life.

Together, the two of them create a framework in which you don’t just jump into cold water, but have an experience that leaves a lasting impact.

BBQ
Delicious specialities from the barbecue, carefully prepared using the finest ingredients.

Extensive salad buffet
Fresh, colourful and homemade – prepared for you with lots of love.

DJ & good vibes
Cool beats will set the mood for the evening. The perfect backdrop to unwind after taking the plunge, to eat, laugh and bid a fitting farewell to summer.
