Experience an Extraordinary Retreat on the Water Surrounded by Nature
The 130-meter-long "Lac Leman Pool," modeled after Switzerland's Lake Geneva, is an outdoor resort pool exclusively for guests. It features three zones: a resort-style swimming area, a 3.5-meter deep diving spot, and a children's pool perfect for first-time swimmers, making it enjoyable for the whole family.
Awaiting the arrival of spring, the Spring Retreat Fair introduces BIG SUP cruising as a new spring activity on "Lac Leman Pool." SUP stands for Stand Up Paddleboard, and as the name suggests, this exhilarating water activity involves standing on a surfboard and paddling across the water.
Other offerings include the new water attraction "Water Roll" and the wellness experience "Floating Sound Bath," where guests float on the forest pool while bathing in sound, providing unique seasonal activities to feel spring's arrival on the water.
